CLP Configuration

CLP can be selected On or Off for the Phase overcurrent, Earth Fault, SEF, and NPS elements independently. It is configured by setting two parameters:

  • Cold Load Time – default 120 minutes

  • Cold Load Multiplier – default x 2.0

Figure 151
WSOS Cold Load settings

The default settings effectively say that the load is expected to completely lose its diversity when it’s been without supply for 120 minutes after which time the Setting Currents for the selected elements would need to be raised x 2 that is doubled.

CLP can be configured in WSOS on the

Protection > Cold Load page or on the operator interface.

CLP is configured per protection group.
