0.01/0.02 class Three Phase High-accuracy Energy Meter Test Bench (PTC-8320H)


1.Features
1.1 The bench accords with the standard of "IEC 60736:1982
Testing equipment for electrical energy meters", "IEC 62053"
1.2The bench can test the converted quantity which is caused by negative phase, voltage unbalance, harmonic wave and so on.
1.3 The bench can auto-calibrate starting, no-load, basic error and calibration tolerance, and 24h deflection.
1.4 Close-link calibration is using insulate current transformer and
suitable for close-link energy meter.
1.5 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.
1.6 The same specification but different constant energy meter can be tested at one time.
1.7 For the installed pick-up equipment can offer 3 ranges adjustment. It is also can be accepted the signal for both round-style energy meter and a digital LED energy meter.
1.8 The bench can choose to operate by keyboard or PC which is
convenient. The working status of the bench can be seen very clear
and easy operation.
1.9 The bench is using the testing software complied with WINDOWS98/2000/XP which can auto-testing different energy meters.
1.10 The software can realize the data from energy meter for statistics, search, and management. It also can connect with on-line management for upload the data.
1.11 The energy meter hanging rack is made by the Aluminum
compound. The whole device configuration is a reasonable design and a nice outfit.
