Calibrator and Tester of measuring instruments

The C300B Calibrator and Tester is used for calibration and testing a wide range of measuring instruments used in power engineering. C300B 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.

Automatic Tester and Error Calculator of power engineering devices

The C300B enables automatic testing with calculating of errors and standard deviation:

electricity meters EN 50470 with accuracy relative to an internal reference of the C300B (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.

Power Calibrator of sinusoidal signals

The 0.02% or 0.05% accuracy of the basic parameters of the C300B Calibrator - voltage, current, power and energy in a wide voltage 21 - 560V and current 0.05 - 120A ranges, is expressed as a percentage of the setting value, without the component as a percentage of the range value. This form of errors specification is very useful when checking instruments, such as electricity meters.

Energy errors diagrams of the C300B Calibrator class 0.02 as a function of current settings for balanced and unbalanced loads at 230V/50Hz and power factor cosφ=1 and 0.5L are presented below.

Data were achieved during production in Calmet by the automatic calibration test procedure using Calpro300TS PC-Software and reference meter Radian RD33. C300B has a build in 200kHz impulse output and two 200kHz impulse inputs so if needed client can easy compare C300B Calibrator to reference standard in any laboratory.

Power Quality Calibrator of nonsinusoidal and time variable signals

Power Quality function enables generation of nonsinusoidal voltage and current waveforms with harmonics, interharmonics and subharmonics as well as simulation of voltage, current, phase shift and frequency variations as a function of time (dips, interruptions, swells, flicker, fluctuations and ramp signals).

PQ functions meet all accuracy requirements of power quality testing to the EN 61000-4 series of standards.
