Neutral Grounding Resistor with safety enclosure. Rated 2400 volts L-N, 400 amps, 10
seconds.
 |
- Designed in strict accordance with IEEE Standard 32-1972
- Reliable, all stainless steel Helidyne™
resistor elements
- Elements are triple insulated from ground for added safety
- Corrosion resistant aluminized steel enclosures
- Fully factory assembled - no field assembly required
- Internal bushings eliminate the need for costly elevating stands

Avtron Neutral Grounding Resistors
are designed to provide added safety to industrial
distribution systems by limiting ground fault current to reasonable
levels. In a typical solidly grounded three phase system, the neutral is
tied directly to earth ground. This can cause high ground fault current
(typically 10,000 to 20,000 amps) and excessive damage to transformers,
generators, motors, wiring, and associated equipment. Inserting an
Avtron Neutral Grounding Resistor between neutral and ground limits
fault current to a safe level (typically 25 to 400 amps) while still
allowing sufficient current flow to operate fault clearing relays |

Avtron Neutral Grounding Transformers are
similar in design to Avtron Neutral Grounding Resistors and provide high resistance
grounding for medium voltage generators and transformers. The standard package consists of
a single-phase, dry-type, Epoxycast™
transformer plus a secondary power resistor, mounted in a common enclosure.
Neutral Grounding Transformer with front cover removed
(shown left). Rated 2400 volts L-N, 10 amps, 60
seconds, with 15KVA 4160:240 P.T. |
