TECHNICAL OVERVIEW

Through On/Offline Data

Heavy Electric Equipment Condition Analysis System

It provides integrated management of offline insulation diagnosis test results and online partial discharge monitoring results.


We provide an optimal solution by analyzing trends and artificial intelligence of offline data.

Prevent failures during operation through online partial discharge monitoring.

ON-LINE TEST

Online Test Assessment

For online test evaluation, we install an Online PD sensor on each machine and measure the machine data in real time.


PACT-Alliance online test evaluation monitors and warns of partial discharge trends and provides expert-level automatic analysis results.

Online Sensor Installation

High Voltage Rotating Machine Online Insulation Diagnosis

All High voltage rotating machine deteriorate as the number of years of service increases, and voids created by deterioration cause partial discharge during operation.


The state of the device can be grasped through trend management of the location and amount of partial discharge during operation.

Online Partial Discharge Analysis 

Online Partial Discharge Applicable Fields 

OFF-LINE TEST

Offline Test Assessment

Specialists directly visit the site and conduct insulation integrity tests of heavy electric equipment (generators, motors, and transformers)

High Voltage Rotating Machine Offline Insulation Diagnosis

In the High voltage rotating machine insulation system (mica-epoxy), voids are created/growth inside the insulator as the operating time elapses, and eventually the insulation is broken.


Through regular testing, the deterioration process is identified, and maintenance such as insulation reinforcement and rewinding is recommended before insulation breakdown.
