The main purpose of a Neutral Grounding Resistor (NGR) is to limit the fault current present in a single line to ground fault. Limiting the possible current that can flow in such an event not only reduces damage to equipment but also helps safeguard personnel in the vicinity. Depending on the design of the resistor, this current value can be either high or low, continuous or of a predetermined duration. The resistor’s designed maximum current allows relays and protection settings to be easily determined and enacted, creating a safe work environment.

Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.
