The role of InsuLogix® RFM is to provide a visible external indication when arcing occurs inside the transformer tank causing an over-pressure condition. The device’s red indicator serves as confirmation that a fault has occurred within the transformer, and the unit should not be re-energized for safety reasons. The InsuLogix® RFM is sensitive enough to detect a pressure increase due to internal low energy arcing which can result from partial discharge, or high energy arcing resulting from short circuits between phases or between phase and ground. InsuLogix® RFM is easy to maintain and comes equipped with a patent pending pressure relief valve for release of internal tank pressure manually or automatically.
Discover the advantages of the InsuLogix® RFM
- Mitigates field personnel risk – danger of closing into a faulted transformer is reduced with a clearly visible flag indicating a transformer with an over-pressure condition
- The device will never activate during transformer testing, transport, or installation
- Cost Savings: Reduces outage time and identifies a faulted transformer reducing troubleshooting time
- Retrofittable to all transformers with a pressure relief valve – no redesign or opening of tank lid
- Maintenance free
