Arrester Leak TesterDAC-LAS-3A

Losses in rotating machines

Simple, Safe, and Fast Diagnosis of Arresters

DAC-LAS-3A can measure the total leakage current, resistive current
(IR) and Third Harmonic content (I3) of leakage current of the arrester by simply clamping the arrester’s grounding line with a CT.

Online Partial Discharge Monitoring & Diagnosis SystemDAC-PD-10

Online Partial Discharge Monitoring and Diagnosis System DAC-PD-10 is a system that monitors PD generated by three-phase rotating machines online. Since diagnosis can be performed while the equipment is still in operation, it can detect equipment and facility problems as soon as possible.
Noise, which is the biggest problem in on-line measurement, has been addressed from both hardware and software aspects to enable separation and identification.
By analyzing the detected PD patterns, the factors causing PD can be identified and risk assessment can be performed.
