Product descriptions from the supplier

Description

Product introduction

Grounding transformers are commonly used to provide an artificial loaded neutral point for the ungrounded point of the system for system grounding. The neutral point of this product is connected to the arc suppression coil or resistor, and then grounded. A secondary winding with a continuous rated capacity can be used as a power source for the station.

Product use

Substations, user distribution stations and other 35kV and below power systems.

Main technical parameters

Rated capacity:100 ~ 5500kVA；
Rated voltage: 35kVand below；
Insulation class: Class A；
Standard basis: GB1094.6；
Ambient temperature: -25 ~ +40℃；
The relative air temperature: the daily average does not exceed 95%, the monthly average does not exceed 90%；
Altitude; Less than 1000m；
The ground inclination is not more than 3, with good grounding network；
Workplace: no fire, explosion risk, no conductive dust, no violent vibration, should leave enough space required by the device.
