摘要： A power supply device comprises a capacitance (Ca) consisting of an overhead power line (100) and an electrode (20) extending in the longitudinal direction of the overhead power line (100) via an insulator (30), an inductance (La) connected in parallel with the capacitance (Ca), and an output portion (50) led out from both ends of a parallel circuit including the capacitance (Ca) and the inductance (La). The parallel circuit is operated as a parallel resonant circuit and power is supplied from the output portion (50), thereby obtaining a compact and simple structure and improving power supply efficiency to a load as compared with a conventional power supply device.

摘要： A system for detecting a power cable for water treeing and other forms of deterioration based on the dielectric loss of the insulation of the cable. An AC test signal is injected to the conductor of a sample of cable to be tested. The voltage drop appearing across a resistor connected to the insulation shield layer of the cable is measured by means of a lock-in amplifier. A phase shifter adds to the voltage drop a voltage signal that is 180 degrees out of phase with the reactive component of the voltage drop. The output of the lock-in amplifier is the active component of the voltage drop that is representative of the dielectric loss of the insulation of the cable. This approach permits an accurate and reliable detection of trees even if they have not spread out evenly in the power cable, as distinct from the conventional tan .delta. method.
