Operation
Phase Loss & Reversal Sensing
The PRR’s output contacts energize when:
1. All the phases are present;
2. The phases are in the proper rotation
3. The frequency is within the tolerance.
If the phase rotation of the incoming three phase lines is reversed, the internal relay will de-energize. Single phase conditions will be detected if there is an 18% loss of voltage in one phase.
