摘要： An apparatus for detecting degradation of a grounded arrester, including a wave conversion circuit for producing an output signal corresponding to the total leakage current flowing through the arrester, and a phase shifter circuit coupled to the output signal for providing a capacitive-component leakage current signal, which is cancelled from the total leakage current signal by means of a differential amplifier to produce a resistive-component leakage current signal. According to one embodiment, this latter signal is applied to a synchronous rectifier circuit for synchronous rectification of the output signal from the differential amplifier circuit. A real resistive-component leakage current signal is then detected by adjusting the phase shift amount in the phase shifter circuit so that the output signal from the synchronous rectifier circuit may become zero, thereby bringing the phase of the cancelling wave signal in agreement with the phase of the capacitive-component leakage current signal. In another embodiment, the resistive-component current leakage signal is applied to a multiplier and a time averaging circuit, the output of which is likewise nulled by means of the adjustable phase shifter.

摘要： An arrester in the shape of a tank has a cylindrical grounding tank as an outer casing to be arranged vertically in which an insulating medium is enclosed. In the grounding tank, a non-linear element group is disposed, the non-linear element group is formed by vertically stacking a plurality of non-linear resisting elements in series at a substantially axially central portion of the grounding tank. A shield having an umbrella-like shape is disposed on a high potential side of the non-linear element group. A shielding unit is operatively connected to a low potential side of the umbrella-shaped shield through a support member. The shielding unit comprises at least one shielding member having a spherical shape provided with a spherical surface portion facing an inner side wall of the grounding tank. When two shielding members are disposed, they are positioned axially symmetrically with respect to the non-linear element group, which comprises a single column or a plurality of symmetrically arranged columns of non-linear resisting element stacks standing upwards along the central axis of the grounding tank.
