Transformer Bushing Monitor
PNX-BM
PNX-BM bushing monitor detects insulation deterioration and other
faults early on, ensuring accuracy and dependability in high-voltage
substation environments. It measures power factor/tan delta and
capacitance for precise early fault analysis, reducing transformer
outages caused by bushing failures.
System for
Effective HV Bushing Condition Assessment
The PNX-BM system is used for periodic monitoring of high voltage (HV) bushing insulation condition of transformers and other HV equipment. These can be both the oil-filled and dry bushings. PNX-BM system could be installed on a bushing test tap with the operating voltage of 110 ÷ 750 kV.
