TV35 DAC Situation Detection Location System

Introduction

DAC is new technology in cable situation checking, and is closely focused by all over the world recent years. The essence of DAC is to use DAC voltage to replace power frequency AC withstand voltage test, on the basis to meet IEC60270 standard. DAC situation detection location system TV10, combines DAC withstand voltage test and partial discharge, to do non-destructive test and provide effective way to find the potential faults. With partial discharge measurement location function, it can locate the fault successfully. It's ideal equipment of operating maintenance department and test department.
