APPLICATIONS OF NEUTRAL GROUNDING (NEUTRAL EARTHING)

Vishay Milwaukee resistor offers a complete line of custom and standard neutral grounding resistors (NGRs), also known as

neutral earthing resistors (NERs). Milwaukee resistor neutral grounding resistors are designed to absorb a large amount of

energy without exceeding temperature limitations defined in IEEE-32. These resistors are used for grounding of generators and

transformers in wye configurations for ground fault, overvoltage, and short circuit protection.

CONTACT THE FACTORY FOR CUSTOM DESIGN AND OPTIONS FOR STANDARD DESIGNS

Options include: current transformers, enclosure style and entrance location, enclosure stands, disconnects, bushings, etc.

For custom designs please include: system voltage, line-neutral voltage, max. on-time, current rating

CSA CODE SPECIAL INSPECTION AVAILABLE UPON REQUEST

An independent, not-for-profit, member-based association dedicated to advancing safety, sustainability, and social good, the

CSA Group is an internationally accredited standards development, testing, and certification organization. By offering CSA code

special inspection for its NGR series of neutral ground resistors, Vishay allows its customers to take advantage of one-time

verification programs that help them get products to the market quickly and safely when certification is not practical.
