Wire Wound Neutral Grounding Resistor

The periodical testing of performance of station batteries is mandatory. The periodical maintenance service improved battery's life and overall performance. The battery discharge resistor is used to conduct the periodical tests. National Resistors offers this convenient to install and use resistor to clients worldwide. Metal steel is used for forming tie rods, which supports wire grid elements made from copper-nickle alloy. The design allows quick and natural cooling of resistor bank. The operator of this unit can also control and monitor the rate of discharge. The clients can choose from switches- DC contractors/circuit breakers or knife edge switches.

Discharge cycle tests help the users to:

Confirm the initial battery performance matches the manufacturers specifications
Early detection of defective cells helps in avoiding deterioration of battery system
Ensures back up systems works smoothly at times of emergency

Information needed for design:

Maximum to minimum battery voltage required to be discharged.
Step by step process of discharge voltage.
Material for resistor element.
