Energy Meter Test Bench for Electrical Utilization Managment Terminal

Energy Meter Test Bench for Electrical Utilization Managment Terminal
Product name : Energy Meter Test Bench for Electrical Utilization Managment Terminal
Item : PEC-T-ZDYA-16
Details :
PEC-T-ZDYA-16 is specially designed for load management terminal, distribution/substation monitoring and measurement terminals to measure comprehensive errors. It can be utilized in labs to measure and evaluate functions, performances and field applicability of various electrical instruments.
It is applicable to factory testing (for electrical utilization management terminal manufacturers), product test before acceptance (for electrical measurement management institutes), and product examination (for lab of power institute).
It is a combination of controlling cabinet, measuring desk and application software. The whole system is consisted of programmable power source, multi function reference standard meter, meter holding table, GPS clock time source, communication ports, measuring ports, display/indication equipment, power loss measurement equipment, function simulators, auxiliary power supply, working station (PC, printer, barcode scanner) etc.
