EE-100A-3S Three-Phase Current Load with Energy Standard Class 0.1 + EE-300V-3 Three-Phase Voltage Generator
Application
The Test System consists of two units:
- Unit 1 – EE-100A-3S – Three-Phase Current Load with Energy Standard Class 0.1
- Unit 2 – EE-300V-3 – Three-Phase Voltage Generator controlled from EE-100A-3S via RS232
The Test System is used for testing electricity meters on-site or in a laboratory. It can generate three-phase voltages and currents, each phase being individually adjustable as amplitude and phase shift versus Va.
All types of electricity meters can be tested with the system – for active, reactive or apparent energy; 2-wire, 3-wire or 4-wire connection.
Advantages
Versatile structure with three main modes of operation:
- Stand alone controllable three-phase voltage and current load;
- Three-phase voltage and current load with energy standard for testing of electricity meters;
- Three-phase current load + energy standard (Unit 1) for testing meters using the voltages of the network;
The phase shifts and amplitudes of all voltages and currents are fully adjustable, which helps to simulate wrong connections or tamper;
Full control from the keyboard and the display on the panel, or from a PC via wireless long distance Bluetooth interface;
Electricity Error Test, Register Test, Starting Current, No Load Test;
Automatic meter error measurements using predefined Test Plans;
