The CP11B Calibrator and Tester is used for calibration and testing a wide range of measuring instruments used in power engineering and enables testing:
AC voltmeters, AC ammeters, frequency meters, phase angle meters, power factor meters, wattmeters, VARmeters, VAmeters, clamps meters and much more,
power quality analysers, recorders and flickermeters IEC 61000-4-30 class A for EN 50160 compatibility or individual requirements of user.
The CP11B enables automatic testing with calculating of errors and standard deviation:
electricity meters EN 50470 with accuracy relative to an internal reference of the CP11B (or relative to an external reference meter) including: measure the basic error and influence of frequency, voltage, self-heating, distortion,…, checking the starting current and no-load run,
electrical measuring transducers for converting a.c. electrical quantities EN 60688 (voltage, current, active power, reactive power, frequency, phase angle, power factor),
current instrument transformers EN 60044 including measure the accuracy of current and phase angle as well as burden measurement,
current clamps with AC & DC voltage and current output including measure the accuracy of current and phase angle,
protective relays EN 60255 including checking of tripping time and tripping level characteristics of ANSI#21 Distance relays, ANSI#27/59 Under/over voltage relays, ANSI#32 Directional power relays, ANSI#50/51 Time overcurrent relays, ANSI#81 Frequency relays and more protective relays.
