7.8 EARTH FAULT SHUTDOWN / ELECTRICAL TRIP ALARM

When the module is suitably connected using the ‘Earth Fault CT’. The module measures Earth Fault
and can optionally be configured to generate an alarm condition (shutdown or electrical trip) when a
specified level is surpassed.

If the

Earth Fault alarm

is enabled, the controller begins following the IDMT ‘curve’. If the

Trip

is

surpassed for an excess amount of time the Alarm triggers (

Shutdown

or

Electric trip

as selected in

Action

).

The higher the Earth Fault, the faster the trip. The speed of the trip is dependent upon the fixed
formula :

T = K x 0.14 / ((I / I

s

)

0.02

-1)

Where:

T is the tripping time in seconds (accurate to +/- 5% or +/- 50ms (whichever is the greater)
K is the time multiplier setting
I is the actual earth current measured

I

s

is the trip setting value

The settings shown in the example above are a screen capture of the DSE factory settings, taken
from the DSE Configuration Suite software.

I

S

(Trip setting

value)

K (time multiplier setting)
