Introduction: In the power industry, ensuring optimal performance of electrical equipment is crucial to prevent costly failures and maintain system reliability. One of the most advanced techniques for achieving this is Partial Discharge (PD) Monitoring, which allows professionals to detect potential faults in electrical systems before they cause catastrophic failures. In this article, we will explore how IPEC offers cutting-edge solutions for PD monitoring, focusing on the key benefits of this technology, along with a real-world case study in Abu Dhabi.
What is Partial Discharge and Why is it Important?
Partial Discharge refers to localized electrical discharges that occur within the insulating materials of high-voltage equipment like cables and switchgear. Although partial discharge may seem minor at first, over time, it can lead to insulation degradation and significant system failures if not detected early. Without early intervention, this can lead to unexpected downtime and costly repairs.
IPEC’s Solutions for Partial Discharge Monitoring:
IPEC specializes in the design and manufacture of advanced Partial Discharge Monitoring and Testing Solutions for the power industry. Their range of products offers versatile options for monitoring and testing PD, from Portable PD Testing Instruments to Permanent PD Monitoring Systems for MV, HV, and EHV systems.
IPEC’s Permanent Partial Discharge Monitoring Systems:
- ASM Permanent PD Monitor: The ASM is a permanent PD monitoring system designed for high-voltage assets like cables, switchgear, and other electrical equipment. It provides continuous monitoring and real-time data collection. In the event of excessive discharge, the system sends an alarm via email or locally, ensuring that asset managers can assess plant conditions quickly and easily. Features: Customizable to accommodate an unlimited number of PD sensor channels. Automatic data download to a central database for easy access and analysis. Suitable for various substation equipment, providing real-time online condition data with just a click.
- ASM-P Portable PD Monitor: The ASM-P is a portable PD monitoring solution, ideal for assessing cables, switchgear, and other high-voltage assets in remote or field locations. This unit is part of IPEC’s wider range of online PD monitoring systems and can be configured with up to 32 sensor channels. Features: Monitors PD Peak, PD Count, Load, Asset Criticality, and Analog data over time. Provides real-time analysis, with up to 8 channels selectable at a time. Flexible configuration options for varied use cases, including small substations and distributed applications.
- DeCIFer – PD Noise Cancelling: DeCIFer is IPEC’s leading algorithm for removing noise and improving the accuracy of partial discharge detection. The system enhances sensor sensitivity and data acquisition quality, ensuring reliable detection of PD events while minimizing false positives. Features: Market-leading PD noise-filtering technology. Automated PD detection using years of accumulated industry expertise. Ensures high-quality data for decision-making with minimal false alarms.
- 1- Case Study at Abu Dhabi Airport – 11 kV Substations: At Abu Dhabi Airport, a project for Partial Discharge monitoring was implemented in 11 kV substations, focusing on critical electrical equipment such as switchboards and cable terminations. Advanced sensors were used to detect Partial Discharge. Challenge: Detecting Partial Discharge in sensitive substations. Solution: AA Ultrasonic Sensor was installed at the cable termination points for PD detection. This device demonstrated high accuracy in identifying areas needing maintenance. Outcome: Early detection of PD prevented potential failures in the system, ensuring power reliability at Abu Dhabi Airport.
- 2- Case Study at Oman Cement Company – 33 kV Substations: Oman Cement Company faced several issues in its 33 kV substations, requiring a solution for detecting Partial Discharge to prevent equipment failure. Challenge: Detecting PD and preventing failures in 33 kV substations. Solution: A Partial Discharge Detector was purchased and used on-site to identify potential issues. During the training session, the team visited the site where there were suspicions of several partial discharge occurrences. Outcome: Upon inspection, more than one instance of Partial Discharge was found, allowing necessary preventive actions to be taken before failures occurred, ensuring continuous operations in the substations.
Key Benefits of Partial Discharge Monitoring Solutions:
- Early Detection: Early identification of Partial Discharge helps reduce unplanned failures and ensures system continuity.
- Reduced Downtime: Monitoring solutions prevent costly unplanned outages, improving operational efficiency.
- Improved Maintenance: Real-time data and detailed analysis enable informed maintenance decisions.
- System Reliability: These solutions enhance the reliability of critical electrical systems, ensuring long-term stability.
Conclusion: Partial Discharge Monitoring is an essential part of modern preventive maintenance strategies in the energy sector. Early detection of PD using advanced sensor technologies can significantly improve the reliability and efficiency of power systems.
