GE Intellix BMT 330

Bushing Monitoring and Partial Discharge Detection for Transformers

Bushings account for a large proportion of High Voltage (HV) substation failures, often causing severe and costly damages. Preventive maintenance, early replacement and regular off-line testing have been employed to address this issue in the past. Now, technology exists that enables asset owners to detect impending failures and reduce their maintenance costs.

GE’s advanced Intellix™ BMT 330 is an on-line system that continuously monitors the condition of the bushings and can also detect developing partial discharge (PD) activity in the transformer main tank. It will alert personnel of fault conditions at an early stage and provide vital health information on the bushings and the transformer.

The Intellix BMT 330 can be utilized as a standalone system to monitor bushing insulation and partial discharge activity, or as an integrated, one-sourced solution with GE’s Kelman TRANSFIX Dissolved Gas Analysis (DGA) multigas analyzer and Perception Fleet software to provide a more in-depth view of the transformer’s condition and root cause of major transformer failures.
