Think inside the box.

The IFD™ sensor is trusted by the world's top utilities to give line crews reliable trouble shooting information on pole mounted and pad mounted transformers, and voltage regulators.

See the signal. Remove the transformer.

The IFD is a sensor that detects and indicates internal arcing faults in pole mounted and pad mounted distribution transformers and voltage regulators. The sensor releases a highly visible orange signal that informs line workers the transformer has an internal fault and needs to be replaced.  No signal, no fault.  The IFD always saves time whether it activates or not.

In addition to improving worker safety, the maintenance free IFD mechanical sensor provides set-it-and-forget-it operation and a typical 12:1 return on investment over the life of the transformer. The IFD represents value whether it activates or not.
