EE-120A-3S Трифазен еталон за енергия клас 0.04 или 0.1 и източник на ток до 120А

Three-Phase Current Load with Energy Standard Class 0.1

Application and brief description

The EE-120A-3S unit consists of a three-phase energy standard class 0.1 and current load up to 120A.
The unit performs testing of all types of electricity meters using the voltages of the network. The meter error can be measured for active, reactive or apparent energy in Manual Mode or with predefined Test Plans using the keyboard and the LCD display on the panel. Maximum Demand Test, Register Test, Starting Current Test and No Load Test can be performed too.
The energy standard of the system can be used without the phantom load to test meters with customer load and perform analysis of the three-phase network – with direct measurement or with optional current clamps.
The analysis includes drawing of a vector diagram, waveforms, harmonic analysis and display of numerical values of power, power factor, voltage, current, phase shift, THT and frequency of the three-phase network.
The test results of 1000 test sites are stored in a non-volatile SD memory card. All these files can be transferred to a PC or viewed on the display of the unit.
All meter and analysis tests can be performed by a PC via EE software.
