Revision A
For example, with a Rated Current of 100 A and a TDS of 0.1, the IDMT will trigger in:
0.15 seconds if the actual generator current is 1000 A
1.35 seconds if the actual generator current is 200 A
6.75 seconds if the actual generator current is 120 A
5.7.3.3 Load Imbalance
Load imbalance provides protection against differences in phase currents.

Name Range Default Description
Imbalance Mode Disable
Trip Only
Shutdown Trip
Disable
Disable: Disables the Load Imbalance
feature.
Trip Only: If Load Imbalance is active, the 62
(RapidCore name) switched output is
activated to switch off the main generator
breaker. This is a latching feature.
The operator must press the (up) and
(down) keys to reset the latch.
Shutdown Trip: Shuts down the engine.
Imbalance Set >
Imbalance 1 ~ 200%
in 1% increments 10% The percentage of rated current that any
phase must exceed the other phases by to
trigger a load imbalance.
Imbalance Set >
Debounce 1 ~ 600 s
in 1 s increments 10 s The length of time to allow an imbalance
before triggering (trip, shutdown).
The load imbalance formula is given as:
For three-phase:
max{|I
A
− I
B
| , |I
A
− I
C
| , |I
B
− I
C
|} > Rated Amps × Phase Imbalance Threshold (%)
For single-phase:
|I
1
− I
2
| > Rated Amps × Phase Imbalance Threshold (%)
where

and

are the actual currents measured by the controller
Note: Phase Imbalance is the same as load imbalance.
