The se 330 is an advanced ground fault and neutral grounding resistor monitoring relay that is compliant with rule10 302 of the 2018 canadian electrical code part i ce code.

Neutral grounding resistor wiring diagram.
Than 40 percent of the rating of the neutral grounding resistor ii.
Low resistance grounding systems neutral grounding resistors ngrs limit the fault current when one phase of the system shorts or arcs to ground.
53 the high resistance neutral grounding equipment will contain the following equipment on the front of the unit as standard.

Earthing of the neutral limits the ground fault current to a high level typically 50 amps or more in order to operate protective fault clearing relays and current transformers.
In solid grounding the system is directly grounded and the fault current is limited only by the soil resistance.
Neutral grounding resistors are used in general to ground transformers or generators with delta or wye secondaries.

It measures current in a transformer or generator neutral neutral to ground voltage and continuity of the neutral grounding resistor.
A backup ground fault detection device to cause deenergization when a ground fault occurs with the neutral grounding resistor open.
The se 325 coordinates these three measurements to detect a failed ngr or a ground fault and provides one.
