The EE Test System is used for testing electricity meters on-site or in a laboratory. It consists of two units:
– Unit 1 – EE-120A-3S – Three-Phase Current Generator up to 120A and Energy Standard class 0.04;
– Unit 2 – EE-500V-3 – Three-Phase Voltage Generator up to 500V controlled from Unit 1 via RS485.
The Phantom Load is able to generate three-phase voltages and currents with unprecedented stability and measurement accuracy. The amplitude and phase-shift of each current and voltage is individually adjustable. All types of electricity meters – mechanical or electronic, for active, reactive or apparent energy, single-phase or three-phase – can be tested with the Energy Standard. The following meter tests can be carried out with the EE Test System: Error Test, Register Test, No Load Test and Starting Current Test. Full analysis of the customer load can also be performed, if current clamps have been ordered. All test results ( maximum 3 Test Plans, 5 Manual Measurements and Customer Load Analysis) can be saved in one file. 100 saved files can be viewed on the LCD display or transferred to a PC via USB port.
