A neutral Earthing resistor restricts the flow of current during an earth fault on an AC distribution system. It is connected between the neural point of a transformaer or generator and earth. Although a neutral earthing resistor will probably be active for just a few seconds during its operational life, it musc offer dependable protection at all time in case of fault. Application can be found in power distribution, mining and industrial installations, indoors and outdoors. Iresco neutral earthing resistors are designed to cope with the most climatic conditions and saliferous atmospheres. These resistors offer distict advantages of durability and reliability
