transformer neutral grounding resistor is the vital need in medium voltage AC distribution network that are also called by different names like Neutral Earthling Resistors. They are taken into use to limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault. They are also used for resistance grounding of connected generators and transformers. You can see use of such systems in industrial power system for resistance grounding of connected generators and transformers; while they are also helpful in limiting the fault current to a value that is sufficient enough to operate protective relays and prevent unwanted fault damage. There are various other features and benefits associated with the transformer neutral grounding resistors.
● The instrument applies high performance single-chip control to achieve test process intelligent
● The instrument is of small volume and convenient to carry
● The instrument is simple in operation and with high precision. It is fast in test speed and reading, intuitively, so it is ideal instrument in accordance with speculation.
