Three Phase Multifunction Energy Meter Test Bench (PTC-8320M)

Three Phase Multifunction Energy Meter Test Bench PTC-8320M  

1. Functions

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

1.2The bench uses three phase wide range multifunctional reference meter, and uses reference energy method to test the error. It can be used to test three phase reference energy meter,three phase  multifunctional energy meter,three phase intelligent energy meter (up to 0.2 class).

1.3 The bench can automatically do starting test, no load test (creep test), error test (accuracy test), deviation test, 24h variation test and so on.

1.4 It can do the influence tests caused by voltage,frequency,
Harmonic and so on.

1.5 Multifunction test: can test the timing error of the day of the multifunction meter; can test the period switching error of the multi-function meter; every meter has RS485 (RS232) communication port, to check the communication protocols and a variety of internal registers of the multifunction meter.

1.6The energy meter hanging rack is made by Aluminum compound. 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 200HZ digital LED energy meter.

2. Features

2.1 The multifunction reference meter and power source can be used independently, and it is convenient to repair.

2.2 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.

2.3 The MTS software platform is very powerful, the main
operations are in one interface, the operation is extremely easy;
and with the SQL SERVER large databases, it is security and
stability, the amount of data is almost unlimited.

2.4 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(RS232).

2.5 Every meter has pulse input port. And it is no need second wiring in the process.

2.6 With the server, multi-meters can be tested at one time.

2.7 The test bench has the auto-search black marker function
which can precisely locate the black marker .

2.8 Automatic range switching. The bench can choose to operate
by keyboard or PC which is very convenient.

2.9 Electronic protection in case of over load, short circuit and output current open status.

2.10 The whole device configuration is a reasonable design and nice outfit.
