RSK-PMT Remote Switch Kit for Pad-Mounted Transformers
The CBS ArcSafe RSK-PMT remote switch kit for pad-mounted transformers permits workers to operate a transformer from outside the arc-flash hazard boundary. When opening panel doors to access the switch on the high-voltage/line side of a transformer, a worker can be exposed to energized conductors on the low-voltage side, which typically carry higher current and the potential of high incident energy.
The RSK-PMT allows for an insulated hot stick to be inserted through a modified door port from outside the transformer. The hot stick serves as an interface between the inside switch and a CBS ArcSafe remote switch actuator (RSA) on the outside, used to turn the inside switch to the desired position. The actuator mounts to the outside of the transformer and turns the hot stick, which rotates the transformer’s switch without the worker needing to open the door and be in harm’s way. Using the radio remote, the worker can be positioned up to 300 feet away as they energize or de-energize the transformer.
RSK-PMT applications include a closed-door-switching (CDS) modification for performing remote operations without the need to open PMT doors for switching tasks. The kit includes the RSA-216 remote switch actuator, the RSO-IV remote switch operator, a wireless radio remote, an exterior-mounted auxiliary door enclosure with an interior alignment tube, and a 2-inch fiberglass hot stick with custom PMT switch adapters, all enclosed in a rugged carrying case.
