Meter Testing Benches

The meter testing benches are designed to work from 3 phase 50 c/s. having voltage 400 to 440 volts between the phases. The test bench is suitable for testing meters under balanced and unbalanced condition of load against rotating sub-standard meters of 5 Amp 240 volts giving accuracy not worse than 0.5. The loading arrangements is based on phantom load principle separate circuit being provided for supplying current and voltage. The bench is provided with indicating instruments of accuracy not worse than 1.5 to indicate Amp and Volts respectively. It is suitable to test 20 Nos. 3 phase meters at a time.
