Features
• The bench complies with the standard of “ IEC 60736:1982 testing equipment for electrical energy meters”, “IEC 62053”
• The bench can be used to test single phase energy meter (up to 0.5 class)
• 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 and test of repeatability of the measurements.
• The bench is using the PWM ,technology 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 signal source is using the newest digital controlled sine wave technology for frequency, amplitude and phase adjust.
• The bench is using comparison technology to test the error 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.
• Different constant energy meter can be tested at one time.
• Voltage is isolated by MSVT(multi secondary voltage transformer)output, which suits for the voltage/current close-link test of signal phase energy meter
• The test bench can be installed scanning head, it can offer 3 ranges adjustment. It is also can be accepted the signal for both round-style energy meter and digital LED energy meter.
• The test bench has the auto-search black marker function which can precisely locate the black marker during the no load test and starting test.
• 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.
• The energy meter hanging rack is made by Aluminum compound. The whole device configuration is a reasonable design and nice outfit
