7.5. Negative Sequence (Fast/Delay) Time Overcurrent (46) 

The EVRC2A has two negative sequence time overcurrent elements. The negative sequence 
element measures the amount of unbalance current in the system. The negative sequence 
overcurrent element can also be used to detect phase to ground and two phase ground faults.  The 
negative sequence time overcurrent element provides a time delay versus current for tripping 
using that an inverse time curve characteristic is operated to coordinate, current pickup value, 
curve type, time dial, time adder, minimum response time setting, and reset type. 
The negative sequence time overcurrent element is enabled in the Primary, Alternate settings and 

[PROTECTION ENABLED]

 on user interface panel. 

Multiple time curves and time dials are available for the negative sequence time overcurrent 
element to closely coordinate with other protection elements in the EVRC2A and other external 
devices on the distribution system. 
The Reset type can be either instantaneous or linear. The negative sequence time delay reset 
mode applies to the ANSI, IEC, ESB, USER curves. The instantaneous mode is used to 
coordinate with other instantaneous reset devices such as a recloser or other protective 
equipment on the distribution system. In the instantaneous mode, the time overcurrent element 
will reset instantaneously when the measured current level drops below the pickup setting for 
one cycle. 
 
If the recloser is closed by pressing the CLOSE button on the front panel, or by an remote 
control or via SCADA, the negative sequence time overcurrent element is prevented from 
tripping for a period specified by the Cold load pickup scheme. 
 

NEG Pickup Current Setup

 

The following setting is used to program the NEQ pickup current.
