CHAPTER 13
PHASE REVERSAL AND PHASE IMBALANCE SET LIMITS/RELAYS

13.1: Phase Reversal and Phase Imbalance

The set limit alerts the user of an unbalanced or a reversed phase in a Three-phase System. The EPM
5300P has two options for this purpose. The standard set-up is clockwise ABC rotation.
Counterclockwise CBA rotation can be selected in GROUP 03.1, Switch C UP.

PHASE REVERSAL

: Activates when a reversed phase enters the EPM 5300P’s metering system.

PERCENT PHASE IMBALANCE

:

Activates when the user's preset value percent phase imbalance is

exceeded. For example: an unbalanced Three-phase System.
Note: The EPM 5200P does not have this capability.

13.2: Trip Relay

NOTE:

All information pertaining to Trip Relays 1 and 2 applies only to a meter with the –NL option.

The unit has two relays linked through the program to LM1

and LM2 Set Limits. The relay outputs can be

programmed individually to close when LM1

and/or LM2

is triggered. Each relay has provisions for a

separate delay (see Chapter 12).

TRIP RELAY 1

Whether to trip Relay 1.

%

TRIP RELAY 2

Whether to trip Relay 2.

&

LEVEL

The level at which the warning mechanism trips percentage of voltage imbalance.

'

ENABLE/DISABLE

In the event of Phase Reversal, whether to enable or disable Phase Reversal
Detection.
