Adjustable 3 * 50VA Three-phase Energy Meter Portable Test Bench

portable and smart,3 meter positions,fine shape, delicate workmanship, complete functions and excellent performance 

1.  Summary

      three-phase energy meter portable test bench is a kind of

      Second generation  program  controlled three-phase energy  meter  test

      device developed in  accordance  with  relevant  national  standards and

      regulations and combined with comments and suggestion of our users and

      experts. It is applicable for testing of three-phase energy meters(including

      positive sine reactive meters) of level 0.2 and below. Featured by fine shape,

      delicate workmanship, complete functions and excellent performance, it is

      an ideal choice for you.

2.  Main characteristics and functions

2.1   The functions of the keys on the special  keyboard are

      clearly identified and the LCD on the special keyboard displays the testing

      equipment working condition.

2.2   During energy meter testing, what needs to do manually is to put up the

      meters to be tested, adjust the photoelectric sampler and setup the meter

      parameters correctly, then all testing items including warming up, creeping

      test,  starting  test  and  basic  error  measurement  can  be  completed

      automatically  by  PC. The testing  procedure can  refer  to the national

      procedure or can be self-defined by the user.

2.3   The photoelectric sampler can realize three-dimensional adjustment. It can

      not only sample the turn-plate signal of the rotary energy meter but also

      receive the strobe signal of the electronic energy meter.

2.4   The  error  processing system can  receive signal from  the photoelectric

      sampler and output pulse of the insert type electronic energy meter.

2.5   Energy meters of same type (same phase, rated voltage and rated current)

      but different constant can be tested Simultaneously (only limited to three

      different constants)

2.6   Locating of marking area of the  rotary energy meter turn-plate can  be

      realized automatically, which enables easier creeping (starting) test.

2.7   The testing equipment is of high stability and reliability, which can provide

strong output power. Voltage (current) loop can take load of any type.

2.8   The testing equipment is provided with complete malfunction checking,

       locating, protecting and alarming functions to avoid damaging of the bench

       resulted from wrong manual wiring or operating.

 2.9  PC  software developed with Delphi for  Windows  95  provides  fast  and

       effective equipment control and data checking, it also provides complete

       functions, such as report printing, quantity counting and assets maintaining
