    Abstract: A sensing apparatus and a sensing method are provided. The sensing apparatus (100) comprises a current sensing circuit (104) configured to sense a secondary current generated from a current transformer (102) to generate a secondary current signal representing the secondary current, the current transformer (102) being configured to receive a primary current from a bus bar to generate the secondary current for supplying a power to the sensing apparatus (100); and a controller (106) configured to detect a peak value of the secondary current signal during a saturation of the current transformer (102), and configured to measure the primary current based on the peak value of the secondary current signal by a look-up table.

    Abstract: An apparatus (100) for monitoring a temperature and a voltage of a cable joint (201) of a cable (200) connected to gas insulated switchgear (300). The apparatus (100) comprises: an adaptor (101) adapted to be coupled to a cable socket (31) of the switchgear (300), a voltage detector (104) coupled to the adaptor (101) and configured to detect a voltage of the adaptor (101); a temperature sensor (102) arranged in the adaptor (101) and configured to detect a temperature of the adaptor (101); a processing circuitry (103) configured to determine the temperature of the cable joint (201) based on the detected temperature of the adaptor (101). A ground terminal (GND2) of the temperature sensor (102) is coupled to a ground terminal (GND1) of the processing circuitry (103), so as to electrically shield the processing circuitry (103) from the voltage of the adaptor (101). The both temperature and voltage of the cable joint (201) may be determined conveniently and precisely. In addition, the impact of the voltage at the cable joint (201) on the processing circuitry (103) can be reduced.

    Abstract: A fault diagnosis apparatus (100) and method (1200) for a circuit breaker (200), comprises at least one sensor (101) coupled to at least one mechanism (201) arranged in the circuit breaker (200) and configured to obtain waveform data of a parameter over time, the waveform data related to an operation state of the at least one mechanism (201); and a processing unit (102) coupled to the at least one sensor (101) and configured to analyze the waveform data to obtain at least one feature value (1220); determine a dissimilarity between the at least one feature value and a threshold matrix (1230); and in response to the dissimilarity being greater than a threshold dissimilarity, determine that the at least one mechanism (201) has a fault (1240). With the fault diagnosis apparatus (100), the fault in the at least one mechanism (201) of the circuit breaker (200) may be determined in advance.

    Abstract: Embodiments of the present disclosure provide a method for monitoring a circuit breaker, comprising the following steps: obtaining a characteristic force associated with an actuating mechanism of the circuit breaker over the time; and determining the time point when the closing and/or opening of the circuit breaker occurs by identifying a variation of the force. The step of determining further comprises determining the moment when a variation increase of the characteristic force occurs as the time point of the closing of the circuit breaker; and determining the moment when a variation decrease of the characteristic force occurs as the time point of the opening of the circuit breaker. The method can be used to accurately on-line monitor the closing and opening time point of the circuit breaker.
