Abstract: A fault detection system and method includes a sensor; a processing unit; and an output unit. The sensor is configured to acquire temperature data at a sensor location of a device, wherein the temperature data comprises first temperature data and second temperature data acquired a first time period after the first temperature data. The processing unit determines a temperature magnitude comprising utilization of the first temperature data and/or the second temperature data, and determines a rate of change of temperature. The processing unit predicts a temperature at a location of the device using the temperature magnitude, the rate of change of temperature, and a correlation, wherein the correlation is a correlation of a plurality of temperature magnitudes and a plurality of rate of change of temperatures at the sensor location with a plurality of hotspot temperatures at the location.

Abstract: A substation contains a switchgear or controlgear, in particular at least one low voltage switchgear or controlgear configured for unmanned operation and maintenance. An inner room, where the switchgear or controlgear are located in, is hermetically enclosed by an outer housing. The inner room is locked against the outer housing by an inner, automatically operated door. A robot system is implemented such that the robot system's acting area is extended from the inner room, partly in the area outside the inner room, but inside the outer housing, where spare parts are stored in a spare parts hand over area, for maintenance.

Abstract: A method for loose joint detection in medium voltage switchgears with busbar joints, circuit breaker upper and lower spouts, and cable connection joints, arranged in an air insulated housing, and medium voltage switchgear itself, in order to create an effective loose joint detection with lower operating expense, but with high performance and accuracy, involves measuring actual temperatures at a first phase as a first temperature (T1), at a second phase as a second temperature (T2), at a third phase as a third temperature (T3), at predefined critical points, such as at the busbar joints, and/or at the circuit breaker upper spouts, and/or at the circuit breaker lower spouts, and/or the cable connection; and comparing temperatures in a logical dependency Ti>(Tj+dT), with i≠j, permuted with i from 1, 2, 3, and j from 1, 2, 3, and setting the alarm if the logical dependency is fulfilled.

Abstract: A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.
