About PD Technology Service

PD Technology Service is a specialized engineering company providing advanced electrical testing, diagnostics, and preventive maintenance solutions for Medium Voltage (MV) and High Voltage (HV) electrical equipment used in industrial facilities and power systems.

Our core expertise lies in Partial Discharge (PD) measurement and analysis, conducted in accordance with IEC 62478 and IEEE standards, enabling early detection of insulation deterioration in critical electrical assets.

Since a significant proportion of electrical insulation failures originate from partial discharge activity, our predictive testing approach helps industries identify potential risks at an early stage. This allows organizations to improve equipment reliability, plant safety, and operational continuity.

With an experienced team of engineers and a strong focus on technical precision and safety, PD Technology Service supports industries in maintaining reliable electrical infrastructure through advanced diagnostic techniques and preventive maintenance practices.

Having successfully completed 500+ projects, we continue to deliver dependable technical services and build long-term relationships with our industrial and power sector clients.

Frequently Asked Questions

Partial discharge testing is a diagnostic technique used to detect insulation defects in electrical equipment before failure occurs. It measures electrical discharges that do not completely bridge the insulation gap but indicate degradation in the insulation system.

It helps identify insulation deterioration at an early stage and prevents unexpected equipment breakdown. Since most electrical insulation failures originate from partial discharge activity, early detection allows predictive maintenance and avoids costly unplanned outages.

No. Our testing is performed under normal operating voltage conditions, without interrupting plant operations. This non-intrusive approach causes no additional stress on the equipment and enables testing at any convenient time.

Power plants (thermal, hydro, nuclear, wind, solar), substations, manufacturing facilities, renewable energy plants, and any industry operating medium or high voltage electrical equipment benefit significantly from PD testing.

We conduct all PD measurements in strict accordance with IEC 62478, IEC 60270, and IEEE Std 1434 standards, ensuring internationally recognized and defensible results.

The frequency depends on the criticality of the equipment, its age, and any prior PD history. As a general guideline, annual testing is recommended for critical HV assets. Our engineers will recommend an appropriate testing interval based on your specific assets.

Yes. We offer flexible Annual Maintenance Contracts tailored to your equipment portfolio, ensuring regular condition monitoring, servicing, and priority response from our technical team.

We are headquartered in Chennai, Tamil Nadu and provide services pan-India. We serve clients in power plants, substations, manufacturing facilities, and industrial parks across the country.
