Equipment Introduction
The cable oscillation wave partial discharge test system is a new type of testing equipment used for field detection and condition diagnosis of cables. It the characteristics of simplicity, practicality, small size, convenient transportation, non-destructive testing of cables under AC voltage conditions, and diversified insulation performance detection and evaluation means. system adopts a combination of damped AC voltage (DAC) withstand voltage test and partial discharge detection, which provides an effective means to discover potential defects in cable insulation
The system can produce damped AC voltage of up to 30kV during the test, combined with advanced system hardware and system software for diagnosis, main technical features include:
Latest semiconductor technology;
Latest laser control technology;
Advanced digital signal processor and filtering technology;
Advanced wireless network control technology
