Connection modes
As it has been previously mentioned, for the GE there are two possible connection modes:
-
Independent phases: Three phase power grid. Each phase (U,V,W) is controlled
independently. The voltage setpoint can be different in angle and magnitude for each
of the three phases.
-
Parallel phases: One phase power grid. In this case the user has one phase output. The
total amount of current consumed will be the sum of all three phases.
It must be remembered that the equipment has 3 output phases (U, V and W) which are
referenced to the neutral point of the system (N). Therefore, the EUT must be connected
between one of the phases and the neutral point (phase-N) or between two phases (phase-
phase). In this way, the power supply could, for instance, feed three independent single-phase
loads at the same time and with different capacities, voltages, currents, etc.
Please be sure that no electrical connection between the phases exists. Keep in
mind that, if two phases are actually interconnected, a shortcircuit may appear in
voltage based modes.
Please remember to disconnect the equipment before modifying the connection
mode.
Working with the equipment
Before powering the cabinet check step by step the following items:
The power supply output (Q2) must be disconnected:
