GENY is a professional energy meter test bench manufacturer with more than 30 years’ history, we are the first energy meter test bench exporter in China, and the equipment have exported to more than 37 countries. The test bench described and offered here is designed and manufactured in compliance with IEC 60736 to meet various requirements in calibration of electricity meters today and the future.
The Three-Phase Energy Meter Test System described here can simultaneously test 1…3, three phase or single phase energy meters.
Normally the following 3 phase energy meters can be tested by this Three-phase energy meter test system: 2 wire-, 3 wire- and 4 wire meters for active and reactive energy.
The Three-phase energy meter test system described here can be operated manually and automatically by PC, and it includes below main parts:
s1 power source which is used to generate tests voltage and current.
s1 reference standard meter with accuracy 0.01% which is the reference standard of the system.
s1 Software package (PC and Printer are optional as customer’s request)
s1 test frame with meter test rack for simultaneously testing 3 meters, and the rack are equipped with:
- 3 scanning head for mechanical or electronic meters
- 3 quick meter connection devices
- 3 individual error display
- 3 error calculator system
- 1 main switch
- 1 emergency stop button
- 1 indication lamp with three colors
Below is the detailed introduction of the main parts of the system.
