An electrical system and a sensor for on-line monitoring of the state of high-voltage insulation in the electrical system. In this arrangement, the signals associated with partial discharge activity are monitored and transmitted from the sensor to monitoring instrumentation. The sensor is interconnected with the potential stress shield of existing bushings. The capacitance in the bushing between the main conductor and the stress shield conducts partial discharge current which is available for being sensed.

A panel, preferably a ceiling panel, for an arc resistant cabinet defines at least one flap dimensioned and configured to bend outward in response to excessive pressure within the cabinet. The flap is bent into a position wherein it will direct high temperature, expanding gases exiting the cabinet away from areas where personnel are likely to be located. The panel also includes a frame below the flap, thereby permitting the entire panel, including the flap, to support the weight of people working on top of the cabinet.

An exhaust chamber for an arc resistant cabinet directs high temperature, expanding gases away from locations where personnel are likely to be present. The exhaust chamber may have an open top, directing gases outward through the center of the exhaust chambers top. Alternatively, the exhaust chamber may be completely enclosed, directing expanding gases through a duct.

Fuses for the potential transformers (PTs) in medium voltage switchgear are mounted in fuse assemblies which are reciprocated within the switchgear enclosure independently of the transformers they protect between a connected position in which the fuse assemblies engage stabs at the rear wall of the enclosure and a retracted position adjacent a door at the front of the enclosure through which the fuses are inserted and removed while the fuse assemblies remain within the enclosure. The fuse assemblies include insulative tubes having first releasable contacts at a distal end which engage the stabs and second releasable contacts which engage fixed contacts connected to the transformers and spaced from the rear wall. The insulative tubes are mounted on a carriage which reciprocates between the connected and retracted positions. An interlock prevents opening of the door except where the carriage is in the retracted position and blocks movement of the carriage with the door open.

An improved design for an electrical insulated "through" boot for a bare joint area formed by two electrical conductors made of a molded member arranged longitudinally around the joint area and having a main body portion with opposed flap members. Each flap member is coextensive with the main body portion and has a distal end. When the molded member is arranged around the joint area, the distal end of each flap member is wrapped around each other in an overlapping manner to form a seal and to enclose the joint area. The ends of the boot can be secured in place by clamps or wire ties. The boot is easily removed without being destroyed for maintenance of the conductors and is therefore reusable. A further embodiment is for a tee boot which has a perpendicular leg which slips over the riser and which has the opposed flap members which are overlapped over the joint area of the bus bars, and a still further embodiment is for a spout boot which involves two pieces wherein one piece is inserted into the other for the overlapping feature around the joint area. Further embodiments provide an end boot and an end cap boot which also increase the creepage distance for the current leakage to prevent breakdown of the voltage source.

Upper and lower compartments are provided in metal-clad switchgear that are mirror images of each other. The compartments have doors that move toward one another to lock. The upper compartment has rails at the bottom for receiving a fuse truck, and the lower compartment has a division sheet between the compartment that has openings in it for receiving mating projections on the doors.

An arc-resistant switchgear cabinet includes a frame disposed on a floor and a door movably mounted on the frame. The frame includes a floor plate that is disposed against the floor and that includes a plurality of pins extending vertically upward from the floor plate. The door includes a plurality of corresponding receptacles into which the pins are received when the door is in a secured position. The pins in the receptacles resist the lower end of the door from moving in a horizontal direction away from the frame in the event of an arcing fault. A pair of bolts additionally fasten the lower comers of the door to the frame. The switchgear cabinet further includes interlocking tabs formed on the frame and on the door that overlap one another when the door is in the secured position.

Electrical switchgear for receiving either a vacuum circuit breaker or a dummy element and including a levering-in assembly with a positional interlock bar that is operated by a levering-in block in the levering-in assembly and by a finger on the dummy element. Access to the levering-in device is blocked when the source breaker is in the connect position. A key to unlock the access is obtained by levering the source breaker or a dummy out to the test position and locking it in that position or by levering a dummy element to a connect position and locking it in that position.

An adjustable door hanger for a sliding door assembly comprises an operator interface and door panel interface connected to the operator interface. The door panel interface is adapted to adjustably engage a door panel such that the door panel is pivotable about the door panel interface. The door panel interface may then be pivoted to a desired resting position. The hanger may include a door panel top rail for receiving the door panel interface. The door panel may be fixed to the door panel interface after pivoting to the desired resting position. A method of hanging a sliding door panel includes providing a door hanger having a door panel interface, attaching a door panel to and pivoting the door panel about the door panel interface to a desired resting position and securing the door panel to the door panel interface.
