For many years the limit for normal apparatus loading was based on the maximum nameplate rating or an arbitrarily set value, called ‘the red line’.

On-line monitoring of power transformers and circuit breakers for condition assessment has gained popularity over the past twenty-five years, the typical technology adoption period, from concept to commercial reality in the electric utility industry.

What are the benefits of implementing End-to-End monitoring of power transformers and
circuit breakers?

• Provides Situational Awareness of electrical assets operating closer to their
  capacity without compromising safety or reliability.
• Fully optimize real-time substation loading/overloading based on actual site conditions, including asset condition or operating modes.
• Assist in making intelligent decisions about load management based on actual circumstances.
• Forecast (predict) operating conditions used to facilitate condition-based maintenance (CBM) programs or agency reporting (such as environmental reporting of SF6 release).
• Collect operational and accumulated loss of life data to enable...
