Avoid unwanted setbacks from lost profits, drop in productivity, delivery deadlines, and severe penalties.

PS Soluções, in partnership with EDF Norte Fluminense, within the scope of the R&D program regulated by the National Electric Energy Agency (ANEEL, Brazil), has developed the Onfra 4.0 project.

OnFRA 4.0 is a product designed for monitoring the insulation condition of electrical equipment. It is primarily composed of an acquisition hardware and a set of coils, with one for injection and another for measurement.

OnFRA 4.0 is primarily designed for monitoring electric motors while in operation. In other words, the system is non-invasive and detects insulation conditions during machine operation.

A study carried out by Electric Power Research Institute (EPRI), involving approximately 7500 large induction motors, identified that 37.5% of failures originated from issues in stator windings. Hence, the importance of early diagnosis of insulation failures is evident. OnFRA 4.0 aims to precisely detect this type of failure and applies to both low and medium-voltage motors.

“Innovation is part of EDF Norte Fluminense DNA. And now, yet another new product is emerging from an R&D project developed in partnership with PS Soluções, which is OnFRA 4.0. It arises from a demand within our plant’s operations and maintenance team and is heading towards the market starting in the second half of 2023.”
