摘要： A monitoring device and a method for monitoring an insulation resistance for an ungrounded electric system includes a liquid cooling operated to ground and having refrigerant flowing in tubes. For this purpose, the measuring signal is supplied in series in the tube system via the refrigerant resistance. The monitoring device is realized having a current measurement or a voltage measurement at the tube sections in order to detect the insulation resistance and can be enhanced for monitoring a shared insulation resistance of several ungrounded electric subsystems fed by a shared transformer.

摘要： A support bracket for a fuse cutout may include an insulating rod with a first threaded standoff at a top end of the insulating rod and a second threaded standoff at a bottom end of the insulating rod. One or more shed sleeves may be secured over an outside surface of the insulating rod between the first threaded standoff and the second threaded standoff. The interior surface of the one or more shed sleeves forms a dielectric interface between the outside surface of the insulating rod and the interior surface of the shed sleeve. A mounting bracket may be secured to a portion of the support bracket between the first threaded standoff and the second threaded standoff. The one or more shed sleeves may be pre-molded prior to installation over the insulating rod.

摘要： A motor driving device includes, a PWM converter that performs power conversion between AC power and DC power in a DC link, an inverter that converts the DC power in the DC link to AC power for a motor and that converts the AC power from the motor to DC power for returning to the DC link, a power storage unit that stores the DC power, a switch that connects or disconnects between an AC power supply and the PWM converter in response to a command, and a command unit that continues outputting a connection command to the switch while a DC voltage in the DC link is boosted up to a prescribed voltage by the DC power, and that initiates outputting a disconnection command to the switch after the DC voltage in the DC link reaches the prescribed voltage and before the inverter initiates powering operation.

摘要： A partial discharge measurement method includes: a moving step of moving an insulated wire including an insulating layer on a surface of the insulated wire; a voltage applying step of bringing an electrode which is connected to a power supply into contact with the insulating layer of the insulated wire which is moving, and applying a predetermined test voltage to the insulating layer while moving the insulated wire; a detection step of detecting, as a partial discharge signal, a signal which is more than or equal to a threshold value among signals involved in partial discharge events occurring from the insulating layer due to application of the predetermined test voltage; and a determination step of determining, based on a result in the detection step, frequency of occurrence of partial discharge events at the predetermined test voltage.

摘要： An integrated circuit is configured to detect current leakage that results from electromigration in the integrated circuit. An isolation power switch selectively connects a target voltage rail in the integrated circuit to a power source. A voltage memory stores a record of an initial voltage decay rate for the target voltage rail while isolated from a manufacturer's power source. A voltage record comparator logic compares the initial voltage decay rate to a field voltage decay rate for the target voltage rail when isolated from a field power source. An output device indicates that a difference between the initial voltage decay rate and the field voltage decay rate for the target voltage rail exceeds a predefined limit, where the difference is a result of current leakage caused by electromigration in the integrated circuit.

摘要： A method of testing an insulation system is disclosed. The method comprises coupling a first test lead to a first conductor, the first conductor at least partly isolated by the insulation system and coupling a second test lead to a second conductor or a ground. The method further comprises applying a test signal to the first test lead, receiving a test response from the second test lead, and analyzing the test response from the second test lead to determine a harmonic content of the test response. The method further comprises, when the harmonic content is equal to or greater than a predetermined threshold, determining that the insulator system has non-linear properties.
