Current Monitoring Parameters
Introduction
This chapter provides information for the current monitoring parameters of the
EC4 Current Monitoring Relay.
Phase Current Reporting
Current Range
The EC4 Current Monitoring Relay utilizes a true RMS algorithm to calculate
the RMS value of the current passing through phase L1, L2, and L3. The relay is
capable of sensing and reporting currents ranging from 0% to 720% of the
maximum current rating.
The following chart illustrates the reporting current precision, the minimum and
maximum reporting current values, and the 720% maximum current rating value
for each current range.
IMPORTANT
The EC4 Current Monitoring Relay will report 0 A if the current is
below 30% of the minimum current rating.
IMPORTANT
The EC4 Current Monitoring Relay is capable of reporting values
greater than 720% of the maximum current rating, but the accuracy of
the value may be compromised.
