  • Patent number: 10247782
    Abstract: A method and a system (9) for testing a switching installation (30) for power transmission installations are provided. The switching installation (30) comprises a switch (2) which either connects a first side (6) of the switch (2) to a second side (7) of the switch (2) or disconnects it therefrom, and comprises two earthing switches (10, 11). Each of the two earthing switches (10, 11) is provided to either connect the first side (6) or the second side (7) to earth (1) or to disconnect it from earth (1). To test the switching installation (30), a current is generated through the switch (2) and a magnitude of the current through the switch (2) is determined. In this respect, the two earthing switches (10, 11) are closed while the current is generated and while the magnitude of the current is determined.

  • Publication number: 20180328991
    Abstract: A method and test device for testing protection relays, the test device having a signal generator. The signal generator supplies a signal as pulses having pause times, which alternate over time. Signal level is reduced during the pause times and at least one pulse has an amplitude at least higher than one of the preceding pulses. A supply voltage is supplied by an accumulator providing electric energy for generating the pulses. Via the accumulator, a greater mobility and flexibility is ensured, and fuel-fed power units or emergency power units may be omitted. In order to reduce the load (average energy) on the accumulator, the signal generator emits the signal as pulses having pause times. The pulse amplitudes may have an increasing trend to reach a switching threshold. This allows the use of smaller and more compact, which is important for a portable test device.

  • Patent number: 10088509
    Abstract: The present method relates to a method for checking a multi-pole electrical circuit breaker. The multi-pole electrical circuit breaker comprises a plurality of poles (101-103). Each of the plurality of poles (101-103) comprises a first connection (121-123) and a second connection (131-133). Closing the particular pole (101-103) makes it possible to electrically connect the first connection (121-123) of the particular pole (101-103) to the second connection (131-133) of the particular pole (101-103) via the pole. In the method, a plurality of micro-ohm measurements are carried out at the plurality of poles (101-103), while the plurality of poles (101-103) are earthed on both sides in a P-P-P-E configuration. A contact resistance of one of the plurality of poles (101-103) is determined on the basis of the plurality of micro-ohm measurements.

  • Patent number: 9244113
    Abstract: This invention concerns methods and devices for calibrating a partial discharge measuring device and for locating faults on cables. In the method, calibration signals, which can include a band-limited white noise, are used with a periodically repeated signal course. By averaging over a predetermined period duration (T) of the calibration signal, it is possible, in the case of a partial discharge measurement, to recalibrate the measuring device continuously during the measurement, and additionally on cables to determine the fault location with great precision.
