Energy Meter Test Bench

الوصف

Three-phase portable three phase energy meter testing equipment is a kind of desk-top portable energy meter testing device which is equipped with a three-phase high-stability program-controlled power source and three-phase multi-function standard meter developed and manufactured by the Company; The device can be operated with keyboard to achieve simple functional tests, control and management may be realized through personal computer. The PC tester has a complete range of test items and the testing device has such advantages as high measurement accuracy, high long-term stability, high degree of automation, wide output range, low distortion, and high stability.

This device is applicable to the testing of electronic and electromechanical single-phase or three-phase active or reactive energy meter as well as multi-function energy meter.

This device can provide you with plenty of electrical information such as AC voltage, AC current, inter-phase voltage and current, power factor, active power, reactive power, apparent power, frequency. One to three meter stations may be connected to this device with built-in or plug-in error processor.
This device can be used for product test in such areas as product development, product maintenance, and production lines. Customer may self-develop its own automatic meter calibration software by making use of the underlying dynamic link library developed by our company.
