摘要： A test system (10) for testing an electric device (30), in particular a high-voltage device, has a portable main device (100) with a housing (140), an electric connection assembly (120, 121) and a mechanical connection assembly (145) and has a portable additional device (200, 300) with a separate housing (240, 340), an electric connection assembly (220, 320) and a mechanical connection assembly (245). The main device (100) can be mechanically connected to the additional device (200, 300) in a releasable manner by coupling the mechanical connection assemblies (145, 245) to form a structural unit, wherein the main device (100) can be electrically connected to the additional device (200, 300) via the first electric connection assemblies (120, 121, 220, 320).

摘要： An apparatus and method for the measurement of a resistance of a switching contact of an electrical circuit breaker. A first resistance value across the circuit breaker is determined while the circuit breaker is grounded at both sides and the switching contact is closed. Further, a second resistance value across the circuit breaker is determined while the circuit breaker is grounded at both sides and the switching contact is open. The resistance of the closed switching contact is then determined based on the first resistance value and the second resistance value.
