Abstract

The present invention relates to an improved system and method for determining quality of power cable insulation using tangent delta measurement. The system (100) comprises a grounded enclosure (101), a power cable (102), a voltage source (104), a power amplifier (103), a current monitor (105) and an oscilloscope (106). The power cable (102) and the power amplifier (103) is contained in the grounded enclosure (101) and are interconnected to the voltage source (104), the current monitor (105), the oscilloscope (106) and the voltage probe (107) during testing. The present invention utilizes an input signal of low voltage and high frequency generated from and amplified by the voltage source (104) and the power amplifier (103) respectively, as well as short power cable samples for determining the quality of the power cable (102) insulation through tangent delta measurement based on an output signal obtained. The present invention also provides a method for determining quality of power cable insulation through an input signal generated and amplified by the voltage source (104) and the power amplifier (103) respectively.
