PDCheck Partial discharge monitoring device - Techimp - Altanova group
The PDCheck device is designed for online monitoring of partial discharges in substation electrical equipment. Partial discharge measurement is one of the most advanced methods for diagnosing insulation. The use of online monitoring allows you to determine the deterioration of insulation at an early stage and track this process over time.The online partial discharge monitoring device manufactured by Techimp (Italy) is designed to monitor the insulation condition of substation electrical equipment by measuring and monitoring partial discharges. Depending on the equipment being monitored, special types of sensors are used.
Areas of use:
- Cable lines
- Electric generators and engines
- Power and instrument transformers
- GIS
- Air insulated switchgear
To evaluate the result obtained, the patented Techimp TF-Map technology is used. Unlike traditional PD evaluation methods, it allows you to divide the received signals into groups for more convenient analysis. The device allows you to accurately determine the type and source of the desired PD signal, even in the presence of strong interference.
Functional features of PDCheck :
- Universal system for measuring, recording and processing data on PD;
- Up to 3 PD recording channels, one channel for synchronization;
- One device for all types of electrical equipment such as cables, transformers, rotating machines and switchgears;
- Ultra wide measurement range;
- An innovative tool for recording and processing partial discharges;
- Diagnostic tools and statistical processing based on fuzzy logic and artificial intelligence;
