    The Phantom Load consists of two units:

    • Unit 1 – EE-120A-3 – Three-Phase Current Load to 120 A (20 A)
    • Unit 2 – EE-500V-3 – Three-Phase Voltage Generator to 500  Vac, controlled from Unit 1 via RS485 (Option).

    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.


    • 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.
      • Manual Mode: Indication in a Table of the Load values – Volts, Amps, Power – P, Q, S, Phase-shift, PF, THD, f. The screen could be turned to  display the “Vector Diagram”.
      • Test Plan Mode: One Test Plan consists of 12 load values, which are changed automatically within pre-set time or with one keypad button used to move the pointer to another line of load parameters. 100 Test Plans can be predefined by the Operator.

    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 generate harmonics (up to 19th harmonic) without need of a PC.

    The phantom load can be controlled from a PC, using EE Software (operating under Windows XP, 7, 8, 10 and later versions).
