The TOTUS Bushing Monitor uses integrated intelligence and analytics to provide reliable and intuitive information to asset managers about bushing health.

Key Challenges

According to statistics published by IEEE, IEC and CIGRE, bushings contribute to roughly 15-30% of transformer failures globally.

In over 40% of cases the failure resulted in catastrophic consequences such as fire, tank rupture and explosions. CIGRE TB 755 reports:

  • bushings cause 5% to 50%, of transformer failures

  • bushing failures are the most common cause of transformer fires and can cause huge collateral damage in the switchyard

  • 30% of generator step-up transformer failures are caused by a bushing malfunction

Minimise the risk with TOTUS Bushing Monitoring

Thanks to monitoring a combination of leakage current & partial discharges we have saved over $10M in damages to bushings for our customers including RIP bushings

Spotlight: Resin Impregnated Paper bushings (RIP)

RIP bushings are made with a void-free impregnation process, designed for a Partial Discharge free operation. However, a combination of extraordinary operating and external events can result in PD in the bushings.

The resin material is not able to withstand the PD activity and will lead to fast degradation and short circuit.

Monitoring PD within the bushings is critical and allows early detection of faults, allowing for fast diagnoses and action. The Image to left shows PD trending in bushings on a RIP bushing.

PD Monitoring, are you doing it right?

Camlin is the ONLY company who can separate the PD in bushings from the PD in the Main Tank. Early detection of PD can significantly improve risk diagnosis, driving quicker accurate decision making.

"Monitoring of Partial Discharges can be easy to apply and understand if put in the right context, correlation of PD with other parameters can help to provide more accurate prescriptive actions and decision making."

Dr Marco Tozzi - Senior Product Manager, Camlin Power
