Paralleling is the operation in which multiple power sources, usually two or more generators, are synchronized and then connected to a common bus. Some applications require two or more generators to be paralleled with the Utility. The frequency, voltage, phase angle and phase rotation of all the sources must match within prescribed limits before they can be paralleled.
Paralleling Switchgear (PSG) is a combination of protection, metering, control and switching elements acting as an integrated system – to control the distribution of power for the following systems;
• Emergency Systems.
• Legally required standby Systems.
• Critical Operation Power Systems (COPS).
• Optional Standby Systems (emergency transfer and load management systems).
