Single Phase Power Calibrator and Tester of Power Engineering Devices

  • Product No:CP11B
  • Manufacturer:Calmet Ltd.

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.
