20100084187 | COUPLER - A coupler that aids in the detection of partial discharge events in a vessel. The coupler comprises a housing for a detector which extends through a wall of the vessel. The housing is sealably connectable to a vessel and is at least partially transparent to electromagnetic radiation. The coupler may be used to allow monitoring of partial discharge events in such vessels as gas and oil insulated subsystems, gas and oil insulated transformers, and gas and oil insulated cables and cable terminations. | 04-08-2010 |
