Our BTS comes with a bespoke Bushing Tap Adaptor (BTA) that detects PD signals from the transformer windings and the bushings, through the capacitance of the bushing
The sensors are installed permanently during a planned outage or at the build stage of a project to enable On-line PD monitoring or spot testing without the need for outages.
The BTS keeps the bushing tap grounded in the same way as the original tap cover, preventing any voltage rise on the bushing tap when in-service and is suitable for outdoor use.
