Client Challenge: Identifying Hidden Electrical Stress & Insulation Risks

Client Sector: Industrial Manufacturing

Voltage Level: 11kV

Service Provided: Online PD Testing & Condition Monitoring

Technology Used: IPEC PD Detector Pro & ASM-C

One of our long-standing industrial clients approached us with concerns about potential insulation degradation within their 11kV substation. Despite regular maintenance, there were signs of electrical stress that conventional electrical inspections couldn’t explain.

The client needed a non-intrusive, real-time diagnosis of their medium-voltage assets without disrupting operations.

The Challenge: Uncovering Hidden Risks in High-Stress Environments

• Problem Detected: Suspected insulation degradation
• Location: Client's 11kV substation
• Objective: Non-intrusive detection of PD without service disruption

Our Solution Using Advanced PD Detection Technology

Online Partial Discharge Survey with PD Detector Pro

We deployed the IPEC PD Detector Pro, a compact, hand-held device designed for walk-through Partial Discharge Testing in MV/HV environments.

To assess the health of the substation equipment, our team conducted an online PD survey using the IPEC PD Detector Pro—a compact, handheld tool ideal for quick and accurate PD detection in high-voltage environments.

🔹 Why PD Detector Pro?

• Lightweight, portable, and easy to operate
• Real-time live data analysis
• Built-in ultrasonic sensors
• Compatible with MV/HV electrical assets

The tool was used during a walk-through survey, allowing our team to identify high-risk areas efficiently without power shutdowns.

Key Findings: Alarming PD Activity in Cable Termination

Our testing revealed significant partial discharge activity at an 11kV cable termination. The root cause? Poor installation practices and reduced clearance, leading to high localized electrical stress.

The PRPD (Phase Resolved Partial Discharge) patterns and ultrasonic data confirmed insulation breakdown—a precursor to possible equipment failure if left unaddressed.

Resolution: Immediate Action & Long-Term Strategy

Using the PD Detector Pro, we promptly assessed the full extent of the issue and provided immediate corrective recommendations. But we didn’t stop there.

To ensure long-term monitoring, we proposed the installation of the IPEC ASM-C system—a permanent online PD monitoring solution.

Why IPEC ASM-C?

The ASM-C continuously monitors partial discharge levels and provides real-time data on insulation health. It features:

✔️ Custom alert settings (email & on-site notifications)
✔️ Remote data access via cloud interface
✔️ 24/7 condition monitoring of MV/HV assets
✔️ Trending analysis to support predictive maintenance

With this solution in place, our client now benefits from early detection, extended equipment life, and improved system reliability.
