PROGRAMMING GROUP 7: PHASE REVERSAL & PHASE IMBALANCE SET LIMITS/RELAYS

11.1VOLTAGE PHASE REVERSAL AND PHASE IMBALANCE

The set limit alerts the user of an unbalanced or a reversed phase in a Three-phase System. The EPM3000P has two options for this purpose.

PHASE REVERSAL:

Activates when a reversed phase enters the EPM3000P’s metering system.

PERCENT PHASE IMBALANCE:

Activates when the user’s present value percent phase imbalance is exceeded. For example: an unbalanced Three- phase System.

11.2TRIP RELAY

NOTE: THE -NLOPTION MUST BE PURCHASED TO HAVE RELAYS TRIGGERED FROM LIMIT CONDITIONS.

The EPM3000P has two Relays. These relays are linked through the program to Set Limits LM1 and LM2. The user can program above or below set limits for every reading. When a measurement exceeds a particular value, the set limit triggers and alerts the user. Each relay has provisions for a separate delay time (see Chapter 8).
