Detail: SN-T3 Three-phase Meter Test Bench

SN-T3 three-phase Electricity Meter Test Bench

Characteristics:

. The bench accords with the standard of IEC 60736: 1982 testing equipment for electrical energy meters, IEC 62053

. The bench can be used to test both single/ three phase active energy meter and reactive energy meter ( up to 0.2 class) , it is also suitable for four quadrant energy meter testing.

. 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( reverse phase, voltage unbalance, harmonic wave and so on) and test of repeatability of the measurements.

. The bench is using the PWM to amplify voltage/ current output, the high efficiency at > 85% , and lower the heat. The PWM can check the malfunction checking, preset, alarm, and protection

. The bench is using the HY 5303C-22 reference standard energy meter with comparison technology to offer the accuracy of energy meters.

. The bench is using the error processor system to calculate the error of each energy meter by the sub-error system, which can be connected by the internal RS485.

. The same specification but different constant energy meter can be tested at one time.

. The bench can choose to operate by keyboard or PC which is very convenient. The working status of bench can be seen very clear and easy operation.

. The bench is using the testing software complied with WINDOWS98/ 2000/ XP which can auto-testing different energy meters.

. The software can realize the data from energy meter for statistics, search and management.
