An electromechanical relay is provided with a housing, a relay assembly within the housing, and a data collection cover enclosing the relay assembly within the housing. The data collection cover includes sensing members that extend in toward the relay assembly and engage disconnect switches of the relay assembly. The sensing members transmit analog signals to an analog-to-digital converter that converts analog signals to digital signals. The cover then stores, displays and/or communicates the digital information.

A test plug has a housing with a first side that has inputs for receiving various connection types, a second side having blades and fingers extending thereform, and a base. The first side extends at an oblique angle from the base, providing accessibility to the input connections thereon. The second side is capable of a removable connection to a test switch in which the fingers separate the current jack contacts before the electrical connection between the test plug blades and test switch jaws is made.

Test plug for a FT switch

A test switch assembly electrically coupled with an electronic module. The electronic module is designed with intelligent sophisticated circuitry that facilitates the transmission and/or the detection of currents and/or voltages between a protective relay and current or voltage transformers. In one embodiment, the electronic test switch senses, detects, monitors, analyzes and/or stores electrical signals and outputs this information to standalone displays, computers. RTU, or similar devices, through wired or wireless connections. The electronic module also allows the test switch to accept electrical connectors such as RJ45, USB, RCA, and/or BNC, among others.
