Overview
RT-BHGZ transformer neutral point gap grounding protection device is specially used for the neutral point of 110KV, 220KV, 330KV, 500KV power transformers to realize two different operation modes of transformer neutral point grounding or ungrounded operation; thereby avoiding damage to the transformer caused by the increase of transformer neutral point voltage due to system failure. This product is widely used in power, metallurgy, petrochemical, construction, environmental protection and other fields.
Current transformer selection: dry current transformer cast with epoxy resin. The current transformer is installed in a stainless steel box, which is not affected by the environment and climate and has a long service life. The protection will not malfunction or refuse to operate and is stable and reliable.
