Three Phase Energy Meter Test Bench PTC-8320D-1
1.1 The bench accords with the standard of "IEC 60736:1982 Testingequipment for electrical energy meters", "IEC 62053".
1.2 The bench can be used to test both single/three phase active Energymeter and reactive energy meter (up to 0.2 class), it is also suitable forfour quadrant test.
1.3 The bench can do warm up test, starting test, no load test(creep test),error test(accuracy test),dial test, tests of the influence quantities(negativephase, voltage unbalance, harmonic wave and so on)and test of repeatability of the measurements.
1.4 The bench is using the PWM, technology to amplify voltage/currentoutput, the high efficiency at >85%, and lower the heat. The PWM cancheck the malfunction checking, preset, alarm, and protection.
1.5 The signal source is using the newest digital controlled sine Wavetechnology for frequency, amplitude and phase adjust. The signal sourcecan repeatedly add 2-21 harmonics on the first sine wave, or couse sub-harmonic wave and odd sub-harmonic wave.
1.6 The bench is using the error processor system to calculate the error ofeach energy meter by the sub-error system which can be connected by theinternal RS485(RS232).
1.7 The same specification but different constant energy meter can Betested at one time.
1.8 The test bench can be installed scanning head, it can offer 3 Rangesadjustment. It is also can be accepted the signal for both round-styleenergy meter and digital LED energy meter.
1.9The test bench has the auto-search black marker function which Canprecisely locate the black marker during the no load test and starting test.
1.10 The bench can choose to operate by keyboard or PC which is Veryconvenient.
1.11 The working status of bench can be seen very clear and easy operation.
1.12 The bench is using the testing software complied with WINDOWS98/2000/XP which can auto-testing different energy meters.
1.13 The software can realize the data from energy meter for statistics,search and management.
1.14The energy meter hanging rack is made by Aluminum compound.The whole device configuration is a reasonable design and nice outfit.
