8 GENERAL DESCRIPTION AND TECHNICAL DATA In this catalogue, Cewe Instrument presents BLUE MO- DULE, a wide range of Transducers for DIN-rail and panel mounting. Thanks to high performance and high reliability e. g. a MTBF of 40 years for current transducers, Cewe Instrument transducers have obtained a wide clientele. The transducers are used by industries and power companies in around 40 countries in Europe as well as in all parts of the world. Below follows general information on electrical measuring transducers with eamples of application, definition of terms and some common data for Cewe Instrument transducers. For each group of transducers then follows an eplanation of working principle, block diagram, and general data. The output from our transducers are within certain limits independent of load. The load limits are given in a data sheets. The load independence is obtained by a certain feedback of the output signal to the amplifier. These transducer charactaristics give great advan-tages among which the most important are mentioned below. 1. Measuring values can be transmitted over relatively long distances. 2. Within the framework of the permitted output signal loadings, several measuring or registration units can be connected simultane-ously to the same transducer. No special tuning is required. 3. No adjustment for wire resistance need to be made in P~ Computer DP 134 CL 48 CL 96 B0086 GB connected instruments. 4. The actual wiring is simple and inepensive in that thin wires can be used for output signals. 5. Individual instruments or other measuring or registration units can be disconnected from a circuit after short-circuiting their connection wires. The signal and the remaining units in the circuit remain unaffected which simplifies service. P~ Computer DP 134 CL 48 CL 96 B0087 GB 6. Maimum open circuit output voltage is low, 20 V, which means that the output circuit can be opened without any precautions. 7. They have a wide range of applications because of their high accuracy and the fact that they are approved in accordance wit interference tests IEC and -6, for input and output signals. Certain A/D-converters and controllers require a positive input signal. For this purpose it is useful to have a zero displacement in power measurements with both positive and negative power. Cewe Instrument s transducers can be produced with zero displacement up to 50 % of the measuring range. Eample: Measuring range kw, output signal ma where 4 ma = 100 kw, 12 ma = 0 kw and 20 ma = +100 kw. See page 11 output signal L. P~ R Computer Eample: to a computer. DP 135 CL 48 B0088GB 8

9 GENERAL DESCRIPTION AND TECHNICAL DATA Addition or subtraction of outputs Summation or different measurements are made by connecting the outputs according to the figures below. This is possible because the outputs are potential free. Cewe Instrument s power transducers are adapted for both summation and different measurements. Other Cewe Instrumenttransducers can be used for summation measurements. P~ + + P~ P P P 1 Summation P 1 + P 2 P 2 - P 1 P~ + + P~ P 2 - P1 Difference P 1 P 2 P 2 - B0089 Live-Zero output Using a measuring transducer with a nominal output of 0 20 ma, there can be an uncertainty when the output is zero, whether the in-put quantity is zero or there is a faulty transformer, transducer or connector. To avoid this we produce transducers with a live zero out-put. This output is normally 4 20 ma for an input of %. These live zero output transducers are frequently used in process technology, but could also be used in power distribution instrumentation. Transducer Indicating instrument As previosly mentioned the transducer output is a DC signal and from that follows that one or several moving-coil instruments often serve as the indicating part. In power distribution technology moving-iron instruments are used for indication and measurements. The movingiron is suppressed in the range 0 20 %, while it is practically linear from 20 to 100 %. If a good A.C. measurement in the range 0 20 % is needed, the combination transducer moving-coil instrument is a suitable choice. I~ A Response time The standard response time is 300 ms. A response time of 50 ms is available as an option. (Ecept for DF and DPF) Other response times on request. In this catalogue the concept response time is used to characterize the time performance of the transducer. Time constant is often used in other cases. The diagram below makes clear the difference between response time and time constant. 99 % 63 % Ripple time constant response time The maimum ripple on the output is < 1 % of the output signal (fs) for transducers in class 0.5. The ma. ripple for transducers in class 0.2 is < 0,5 %. t B0224GB 0 B0825 9

10 GENERAL DESCRIPTION AND TECHNICAL DATA Linearity A transducer is linear when the output is proportional to the input. A deviation from a linear function is called a non-linearity error and is epressed as a percentage of a range in our data sheets. Auiliary supply voltage Cewe Instrument transducers with some eceptions are designed for 110 V A.C. or 230 V A.C. ±20 % auiliary supply voltage. Further information on this can be found in the preamble of each transducer type description. Cewe Instrument transducers are also manufactured with a switched power supply in two ranges; V AC/DC (i.e ± 20%) and V AC/DC (i.e ± 20%). In case of auiliary supply with a DC voltage the connection is unaffected by the polarity. Types DU 120 and DI 120 do not require an auiliary power supply. The accuracy class Nominal accuracy class 0.5. Optional 0.2 Cewe Instrument transducers are calibrated to a nominal accuracy value with a maimum error of 0.1% for class 0.2 transducers, and 0.2% for class 0.5 transducers. The reference conditions are a power factor of 1.0. Additional class number factors which influence the accuracy are: Auiliary supply voltage variations The auiliary supply voltage can be varied within wide limits, without any appreciable affection of the measuring accuracy. Measurement error is less than 0,1 % of measuring range. Temperature variations Cewe Instrument transducers are calibrated at an ambient temperature of +23 C. At other temperatures a temperature error has to be added. This error varies between different transducer types. The temperature dependence is separately given in each data sheet. Phase angle variations The phase angle between the current and the voltage is of great importance when measuring the power. The additional error obtained when the phase angle varies is small and is epressed within the indicated class number as a % of the full output signal at ±90º. The values can be found in the product data sheet for the transducer concerned. 10 I ma I Ideal function True function I Non linearity = out 100 [%] I out ma B0100 Casing The casing is made of self-etinguishing polycarbonate.

Otherwise ma 75% Otherwise ma 85% Year average ma 65% Year average ma 75% Mounting position The measuring transducers can be mounted in any arbitrary position. The mounting position does not affect the measuring accuracy. Temperature range Under general data for each transducer type, the three temperature ranges are given: working temperature C, function temperature C and storage temperature C. Working temperature range imply the temperature range within which the given data are valid. Function temperature range imply the transducer functions within this range, but can show a somewhat higher temp. coefficient. Storage temperature range imply that the transducer stands to be stored within this temperature interval witout being damaged. Mounting The transducers are mounted easily and quickly on DIN rail type DIN EN A plastic DIN rail, Art No. 4025, can be supplied for mounting single transducers. The rail can easily be cut to the correct length for the relevant case size. See page 59. s The screw terminals are located on the front of the transducer and have a so-called self-opening washer, which facilitates assembly. The terminals can accept a maimum conductor area of mm 2. The transducers are always supplied with protection against accidental contact. Forms of enclosure (Protection degrees) Case seal = IP 51 Terminal part = IP 20

11 Standards Cewe Instrument measurement transducers are tested according to the standards of the EMC Directive and according to IEC and -6 Interference environ-mental classes and test regulations for electronic apparatuses in control equipment for power stations. The transducers are manufactured to IEC EMC directives IEC Emissions light industry IEC Emissions heavy industry IEC Immunity light industry IEC Immunity heavy industry LVD directive IEC IEC Safety Safety For all transducers that are connected to transformers, the secondary side of the transformer must be provided with a protective earth.

26 TRANSDUCERS DP, DQ AND DPQ FOR ACTIVE AND REACTIVE POWER Transducer type DP, DQ and DPQ measures the active (P) and reactive (Q) A.C.-power and converts these into proportional load-independent DC current signals. The measurement principle for multiplication of the current and the voltage is based on the TDM (Time-Division-Multiplication) method. The measurement principle also takes account of the curve form error and the phase angle difference ( ϕ = ) between the current and the voltage and gives the true power value (true RMS) as its result. In transducer DPQ the signal outputs (P) and (Q) are galvanically separated from one another. The measurement voltage and measurement current can be connected directly to the transducer or via measurement transformers. The permitted value for the scale factor shall lie within the range and shall be defined by the scale factor formula. The current may not eceed 10 A.

51 TRANSDUCERS DR FOR RESISTANCE Type DR 134 to 435 Transducers type DR are used to measure resistance that is converted into a proportional, load-independent galvanic isolated DC voltage or DC current signal. Transducer DR can be connected, for eample, to resistance sensors in a two-wire, three-wire or potentiometer circuit. Measurement principle, three-wire circuit: This eliminates the resistive effect of wiring between the transducer and the sensor. It is essential to use a three-wire circuit with use of Pt100 sensors, and with combination with linearisation, an output signal proportional to the temperature is obtained. Measurement principle, two-wire circuit: This is used in applications where the resistance of the wiring is negligible relative to R. Potentiometer circuit: Used in conjunction with mechanical moving sensors such as position transmitters. U au 1 R DR (Potentiometer) DR R (2-wire) + data DR Accuracy class (Option) Linearity error < 0.2 % <0.1 % Load-dependence <0.05 % <0.05 % Response time (0-99%) ms ms Auiliary voltage dependence < 0.1 % < 0.1 % Temperature dependence < 0.1 %/10 C < 0.06 %/10 C Ma voltage with open output 20 V 20 V Ma output signal with over-driven input signal <125 % <125 % Ripple (peak-to-peak) <1.0 % <0.5 % General data Working temp. range C Function temp. range C Storage temp. range C Test voltage 5.55 kv, 50 Hz signals R (3-wire) DR C (3-wire) Dimensions and weights See page 58 A B C D I K L B0857GB B0732GB 51
