7 BS - Technical infoation OVERCURRENT REEASES The electronic overcurrent release consists of a separate and interchangeable unit, which is supplied with the BSE... switching unit. By exchanging the overcurrent release, the range of the circuit breaker s rated current can be easily changed. Releases for the BSE switching unit are produced in four current ranges n =,, and A. The releases, including their adjustment, cover rated currents ranging from to A. Depending upon the needs for adjusting the release s tripping characteristic to the protected device and to the variability of the characteristic with regard to selectivity, the following release devices are available: DTV They have one type of characteristic with adjustable r and. MTV They have more kinds of characteristics with adjustable r, t r and. U They have universal characteristic, with the greatest variability in adjustment: r, t r, v, t v and. DTV, MTV, U Proper functioning of releases does not depend on the fo of current in the power circuit. The function of the release is supported by a microprocessor, which processes a sampled signal of the power circuit and recalculates it to obtain an s value. Therefore, digital releases are suitable for protecting circuits where the sinusoidal current is distorted by high haonics (e.g. circuits with controlled rectifiers, power factor compensators, pulse loading, and the like). All the releases protect a circuit against short-circuiting and overloading. Setting of selective cascading of circuit breakers is especially enabled by the U release. Tripping characteristic of the releases is independent of the ambient temperature. The release is affixed to the switching unit by two bolts. The translucent cover over the adjustment controls can be sealed. Tripping characteristic adjustment for DTV and MTV releases The tripping characteristic of overcurrent releases is defined by standard EN 7-. The characteristic is adjusted in two zones using latched switches on the overcurrent release unit: - is a zone of low overcurrents and includes the area of theal protection. DTV t r MTV - is a zone of high overcurrents and includes protection against ultimate short-circuit currents. For MTV releases, the time delay can be set at or ms.. Dependent release (theal) The dependent release DTV is adjusted using one r switch. The r switch is used to adjust the circuit breaker s rated current. The characteristic is moved on the current axis. By means of its internal circuitry, the release is set to one type of characteristic. The dependent release MTV is adjusted using two switches, r and t r. The first ( r ) switch is used to adjust the circuit breaker s rated current. The characteristic is moved on the current axis. By turning the other switch (t r ), the time is adjusted after which the circuit breaker will trip while passing through 7. r. The tripping characteristic thus moves on the time axis. Using the t r switch, it is possible to set a total of characteristics. Four characteristics are available for motors protection. Breaking times correspond with the release class A,,,. By changing t r, it is possible to select the characteristic according to the required motor starting (light, medium, heavy or very heavy starting). For protecting transfoers and lines, characteristics can be set. t is not possible to turn the device back on right after the dependent release has been actuated and circuit breaker tripped. The release must be allowed to cool off, because it has a theal memory. The memory can be disabled by turning the restart switch from the noal T t position to the T position. The dependent release remains active, and only its theal memory is inactivated. Switching off the theal memory should be used only in well-justified cases, and with the knowledge that there could be rising temperature in the protected device with repeated tripping.. ndependent instantaneous release (short-circuit trip) The independent instantaneous release in designs DTV and MTV is adjusted using one switch,. The switch is used for setting up the short-circuit current that, upon its being reached or exceeded, causes instantaneous tripping of the circuit breaker. Regulation of the short-circuit release takes in settings for the characteristic appropriate for protecting lines and motors. The wave fo of the tripping characteristic is adjusted using latched switches on the release s front panel according to the needs of the protected device. A visual demonstration on setting the tripping characteristic can be found in the SCHR program (see t r tr P Tripping characteristics of DTV and MTV releases with load The tripping characteristic from the cold state indicates the tripping times during which it is assumed that, up to the moment when an overcurrent develops, no current is flowing through the circuit breaker. The tripping characteristic tripped from wa state indicates the tripping times during which it [%] r is assumed that, before the moment when an overcurrent develops, current is flowing through the circuit breaker. Characteristics of electronic releases are independent of the ambient temperature and are plotted in a cold state. Digital releases enable simulation of a release in wa state. The tripping times become shorter in a steady state, as shown in the following graph. The steady state is a period during which the characteristic does not change. f the circuit breaker is loaded with a reduced current for at least minutes, the tripping times will be cut by a half. f the load is less than 7% of r, the tripping time does not become shorter. DTV and MTV tripping times shortening with load T - When tripping from the release s wa state, the tripping time of the characteristic is cut short during the standstill time t u by coefficient k. Theal standstill time of the characteristics For all kinds of characteristics tr, the theal standstill time for MTV and DTV releases is t u min. During this time, the short-circuit tripping time t v is cut short from the cold-state characteristic by the coefficient k. The real tripping time is t s = k. t v Example The shortening constant can be read from the graph. With steady current % of r the real tripping time will be shortened to: t s =.7. t v k [ ] time shortening coefficient r [A] adjusted rated current of the overcurrent release t v [s] tripping time of the release derived from the characteristic t s [s] real tripping time of the release tripped from wa state t u [s] standstill period for particular characteristics T Overcurrent releases are set by the manufacturer r = min Restart = = min, ms t r = TV, min G7

8 BS - Technical infoation OVERCURRENT REEASES P Tripping characteristic adjustment, release U S t r tr should be used only in well-justified cases, and with the knowledge that there could be rising temperature in the protected device with repeated tripping.. Delayed independent release S The delayed independent release has the function of a delayed short-circuit release. t is used to set up a selective cascade of circuit breakers. t is set up using specifications v and t v. Tripping time shortening with load T v toff ton tv The tripping characteristic of overcurrent releases is defined by standard EN 7-. The characteristic is adjusted in three zones using latched switches on the overcurrent release unit: - is a zone of low overcurrents and includes the area of theal protection. S - is a zone of medium overcurrents and includes longdistance short-circuit protection for lines. ntentional delay in tripping of these low short-circuit currents can be used to achieve selectivity of protective devices. This type of delay can be set only in self-contained releases (full version). - is a zone of high overcurrents and includes protection against ultimate short-circuit circuits without time delay. t - Characteristic setting in the ON position represents a constant value of energy passed through. f fuses are used as protective elements for outgoing branch feeders, it is possible to adjust the selective part of the characteristics to better suit the shape of the fuse characteristics.. Dependent release (theal) The dependent release U is adjusted using two switches, r and t r. Using the first switch, r, the circuit breaker s rated current is adjusted. The characteristic is moved on the current axis. Turning the second switch, t r, adjusts the time after which the circuit breaker will trip while passing through 7. r. The tripping characteristic thus moves on the time axis. Using the t r switch a total of characteristics can be set. Breaking times correspond with the release class A,,,. t is not possible to turn the device back on right after the dependent release has been actuated and circuit breaker tripped. The release must be allowed to cool off, because it has a theal memory. The memory can be disabled by turning the restart switch from the noal T t position to the T position. The dependent release remains active, and only its theal memory is inactivated. Switching off the theal memory v is an n-multiple of current r ( v = n r ). t is a shortcircuit current that, within the span of v to, will trip the circuit breaker with delay t v, where t v is a delay set up for switching off the release. The delayed independent release actuates the circuit breaker if the current in the circuit reaches at least the preset n-multiple and lasts at least the preset delay time t v. The independent release can be disabled by setting the parameter n ( v = n r ) into the position. Parameter t v can be set to values with respect to the energy that passed through l t (switch position l t on). The preset time values are then applicable for currents more than x current r. Tripping times of k-multiples of r for k < are defined as follows:. ndependent instantaneous release The independent instantaneous release has the function of a short-circuit release. t is set up only on parameter. is short-circuit current that, upon its being reached or exceeded, causes the circuit breaker instantaneously to switch off. t is set up directly in ka on the release. The wave fo of the tripping characteristic is adjusted using latched switches on the release s front panel according to the needs of the protected device. A visual demonstration on setting the tripping characteristic can be found in the SCHR program (see Tripping characteristic U release with load The tripping characteristic from the cold state indicates the tripping times during which it is assumed that, up to the moment when an overcurrent develops, no current is flowing through the circuit breaker. The tripping characteristic tripped from wa state indicates the tripping times during which it is assumed that, before the moment when an overcurrent develops, current is flowing through the circuit breaker. Characteristics of electronic releases are independent of the ambient temperature and are plotted in a cold state. Digital releases enable simulation of a release in wa state. The tripping times become shorter in a steady state, as shown in the following graph. The steady state is a period during which the characteristic does not change. f the circuit breaker is loaded with a reduced current for at least minutes, the tripping times will be cut by a half. f the load is less than 7% of r, the tripping time does not become shorter. T - When tripping from the release s wa state, the tripping time of the characteristic is cut short during the standstill time tu by coefficient k. Theal standstill time of the characteristics For all kinds of characteristics t r the theal standstill period for U releases is t u min. During this time, the short-circuit tripping time t v is cut short from the cold-state characteristic by the coefficient k. The real tripping time is t s = k. t v Example The shortening constant can be read from the graph.

Operation of the release is controlled by a microprocessor. The release is outfitted with a theal memory that can be disabled by turning the switch on the front panel from position to position. After disabling the theal memory, the theal release remains active. A practical advantage of the release is a specially designed tripping characteristic that provides for optimal exploitation of transfoers up to n. Another advantage of this release is the simple adjustment of the tripping characteristic. Set-up includes only the rated current in a range of. to. of n and the short-circuit tripping level. The reaching of % and % of r is indicated by ED diodes on the front panel denoted as > % and > % of r. On the lower part of the release cover are four photocells for communicating with the SB-B- signalling unit. Specifications - adjustable Type n [A] r [A] restart SE-B-J-DTV, 7, 7,,,, 7,,..

10 BS - Technical infoation OVERCURRENT REEASES MTV - MOTORS P Direct protection of motors and generators Possibility for protecting lines and transfoers Description The SE-B-J...-MTV release is intended only for the BSE... switching unit. The operation of the release is controlled by a microprocessor. The release is equipped with a theal memory that can be disabled by turning a switch on the front panel from position to position. After disabling the theal memory, the theal release remains active. A practical advantage of the release is a specially designed tripping characteristic that provides for optimal exploitation of transfoers up to n. t is possible to set a total of characteristics on the release. From these, in mode M there are characteristics for motors protection and another characteristics in mode T V for protecting transfoers and lines. The shape of each characteristic can be changed using a selector switch. When one or two phases fail, in the M-characteristic mode, the switch will open with a s delay (so-called undercurrent release). Another parameter for adjusting the release is rated current, which is adjusted in a range of. to. of n and the shortcircuit tripping level, for which it is possible to set the delay at or ms. The reaching of % and % of r is indicated by ED diodes on the front panel denoted as > % of r and > % of r.

12 BS - Technical infoation OVERCURRENT REEASES U - UNVERSA P Protecting complicated loads or those not specified in advance Description The SE-B-J...-U release is intended only for the BSE... switching unit. The release is equipped with a theal memory that can be disabled by turning the restart switch on the front panel from the position to the position. After disabling the theal memory, the theal release remains active. A practical advantage of the release is its maximum flexibility for adjusting the tripping characteristic. With its possibility for setting t = constant and t = constant, it is optimal from the selectivity viewpoint for its interaction with fusing devices. The operational state 7% of r is signalled by an ED indicator that flashes green in a s interval. As the load grows, the blinking frequency of the diode increases. n case of a load larger than % of r this ED will turn red and just before tripping will begin to blink red. On the lower part of the release cover are four photocells for communicating with the SB-B- signalling unit.
