Three Phase Power Calibrator and Tester of Power Engineering Devices
Three phase, class 0.02 and 0.05 power quality calibrator up to 120A (360A) and 560VAC with programmable power quality parameters. It makes possible to make automatic test of electricity meters, measurement transducers, current transformers and protection relays.
C300B is an universal device with many measurement functions and can be used as a:
- Calibrator and Tester of measuring instruments
- Automatic Tester and Error Calculator of power engineering devices
- Power Calibrator of sinusoidal signals
- Power Quality Calibrator of nonsinusoidal and time variable signals
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:
Automatic Tester and Error Calculator of power engineering devices
The C300B enables automatic testing with calculating of errors and standard deviation:
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.
