EE-120A-3 + EE-500V-3
Portable Three-phase Phantom Load
Application and brief description
The Phantom Load consists of two units:
– Unit 1 – EE-120A-3 – Three-Phase Current Generator up to 120A
– Unit 2 – EE-500V-3 – Three-Phase Voltage Generator 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. The generated values of voltage, current, power, power factor, phase shift, THD and frequency are indicated on the LCD display.
Advantages
- Flexible structure – the current generator can be used alone for on-site measurements, generating current synchronized with the available service voltage.
- Two generation modes – Manual mode and Test Plan mode are at Operator’s disposal. The Test Plan mode is used for easy change of load parameters, using only one panel keypad button. 100 Test Plans can be predefined by the Operator, each one with 12 test points.
- The unique stability and measurement accuracy make the phantom load suitable for testing not only electricity meters, but also other measuring devices in a substation like amp-meters, volt-meters, power and power factor meters.
- The phantom load can be controlled from a PC, using EE Software (operating under Windows XP and later versions). In this case, additional functions are available, such as generation of harmonics to the 31st, vector diagram and wave form display.
- The EE-120A-3 unit can be upgraded with new firmware, which allows the integrated energy standard (class 0.04) to be used for testing electricity meters, thus forming an independent Test System.
