Partial Discharge - PDG

About PDG

The Partial Discharge Guard is designed to monitor medium to large transformers in order to extract a signature of its condition. Without such Condition Monitoring (CM) ability it is difficult to know when a motor needs to be serviced. Motor rewinds can be very costly. Wear or poor lubrication of bearings can lead to catastrophic failure. Adopting Partial Discharge is the key to decreased expenses. It provides long term evaluation of your transfomrers and ability to service components before it’s too late. Proper monitoring is essential for power grid optimization. The sensor (VibroFibre) has the dual ability to measure vibration from the end winding (2xLF: two times line frequency) and temperature.

Key Features

✔ Broadband sensor working from 20 Hz to 2,000 Hz.
✔ 1 channel system for both temperature and vibration.
✔ Calibrated to industry standard: 1G per 100 mV at 159.2 Hz.
✔ ​Immune to EMI and high voltages.
✔ ​Signal Conditioner possesses an analog electrical output for direct measurement. 
✔ ​A SCADA device can be linked to the Signal Conditioner as it also outputs RS-485 Modbus signal.
✔ The signal conditioner allows portability and thus capacity of evaluating a whole fleet of motors, further increasing the cost effectiveness of the system.
✔ The Motor Guard system can be extended to other types of assets and conditions.

Graphical User Interface

Motor EYE MOTOR EYE is an online software service enabling the user to observe measurements in real-time. Displayed are the time and frequency domains, and temperature as well. Plus, data can be stored for long term independent monitoring for the sake of trending the signature using MOTOR SAFE software service.

Motor SAFE ​Offline software service trending the saved data from its online counterpart. Long term behavior of your induction motor becomes apparent.
