Close-Link Three Phase Energy Meters Test Bench with Isolated CT for 24 Positions
First steps in the production of fully electronic automatic electricity meter calibration systems were made 10 years ago by KAIPU. The system described and offered here comprises components based on most modern technologies. It therefore combines long term experience in this field with the application of state of the art technology.The recently developed new software is based on KAIPU ’s historical experience in providing various testing solution to numbers of manufacturers, Utility companies, Metrological institutes etc.
Power supply: 220V+10%, 50Hz/60Hz
Maximum power consumption: 1000VA (reference for 24 positions)
The offered universal meter testing equipment is designed for the simultaneous testing,
adjustment and certification of meters.
The following electricity meters of the accuracy classes 0.2, 0.5, 1 and 2 can be tested:
*2 wire-, 3 wire- and 4 wire meters for active and reactive energy (true and cross-connected),
The test system incorporates a completely electronic test current- and test voltage
generation. The working standard is a wide range substandard meter directly connected to the test circuit.
A PC system controls the test system and supervises the test procedure. The actual
values of test voltage and -current and the errors of the meters under test are displayed on the monitor. The errors of the meters are indicated additionally on error displays at each measuring position.
Structure and main parts
① Error calculator
② Bracket(socket) for tested meter
③ RS485 Communication Port
④ pulse input
⑤ power switch
⑥ Power on for amplifier
⑦ Power off for amplifier
⑧ signal generator
⑨ three phase reference meter
⑩ voltage output from power source
⑾ current shortcut(In this test bench, when worker use meter position 1 - meter position 8, the above 3 current shortcut should be closed and the under 2 current shortcut should be open.
When worker use meter position 9 - meter position 16, the above 3 current shortcut should be
open and the under 2 current shortcut should be closed. )
⑿ amplifier (voltage & current)
⒀ range shifter (voltage & current)
