High Resistance Neutral Grounding Resistor

Their     resistance value is precise and determined at the manufacturing stage     remaining constant throughout their life

Their     temperature Time constant is shorter allowing a resistor of shorter time     rating to be used

They are     easier to install on site

They require     virtually no maintenance and have a longer useful life

No anti frost     heating is required nor Anti Condensation Heaters generally

Because of     problem resulting from the evaporation of gel and electrolyte the liquid     resistor require constant maintenance

Invariably     the type of cooling will be natural air-cooling
