DPT-30ATransformer comprehensive protectionmonitordeviceapply to35kV and belowVoltage levelTwo coil transformerProtection and monitoring.

DPT-31A and DPT-32A are suitable for plant transformer protection. It is recommended to use DPT-31A plant transformer protection for transformers below 2000KVA,Greater than 2000kV~5000KVA

DPT-32A differential backup integrated plant transformer protection can be used. DPT-32A is equipped with zero sequence current protection on both high and low voltage sides,Simulate reaching a maximum of 15 routes,head

The factory transformer has a differential and backup integrated protection device.

DPT-33AandDPT-34ASuitable for main transformer protection,DPT-33AUsed for single backup protection of transformers,DPT-34AEquipped with differential protection and backup protection functions,

The combination of the two is used to achieve35kV main transformer protection device.
