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.
