Description

220 Kv 240 MVA Oil Immersed Power Transformer Earthing Transformer

Product Overview

For 220kV Oil immersed type transformer,which is substation main transformer.The grounding transformer is used to provide a path to an ungrounded system or when the system neutral is not available for some reason, for example, when a system is delta connected. It provides a low impedance path to the neutral and also limits the transient overvoltage when the ground faults occur in the system. The grounding of the system can be done in the following way

Usage Environment

1. Elevation: Not more than 2000 meters.

2. Ambient temperature:

Max. + 50℃.

Min.: -45℃.
