Composite Insulators, Past, Present & Future: Views from Late Industry Titan, Dr. Laurent Pargamin

INMR and its community of readers across the globe mourn the recent passing of Dr. Laurent Pargamin, former Scientific Director and Senior Executive at Sediver in France. Read More >

Sum of Currents vs. Voltage Reference for Monitoring Bushings: Case Studies

Utilities look to online monitoring as an effective means to identify possible degradation of transformer bushings early on and avoid catastrophic failures. Read More >

Reviewing High Voltage Insulator Coatings

Foam-Filled Post Insulators for Substations & Compact OHL Applications

Experience Commissioning Testing HV Power Cables (Video)

Case Study of Partial Discharge & Commissioning Testing of Long (+20 km) 400 kV XLPE Cables

in HV/HP Testing

Even the most rigorous factory testing cannot guarantee that cables will be installed correctly or that they will not be damaged during transport or laying and future owners require commission tests before accepting ownership. Read More >
Procedures & Challenges When Dimensioning DC Insulators

in Insulators

Insulators require careful scrutiny since they show significantly different behavior under DC stress than under AC stress. Read More >
Evaluating Condition of Old Porcelain Cap & Pin Suspension Insulators

in Insulators

Many insulators in service are either reaching or have already crossed the threshold of their expected operational lifetime. Read More >
Failure of Transmission Line Insulators

in Insulators

It is unrealistic to expect that any network component can last forever without failing and it can therefore be assumed that some proportion of insulators will fail in service after a certain period of time. Read More >
Increasing Transformer Reliability by Proactive Bushing Fleet Management

in All Articles, Bushings

If a bushing fails, the typical result is extended downtime of a power transformer with not only heavy financial losses but also challenges imposed on the system operator to compensate for the lost unit. Read More >
PD Measurements for HVDC Cable Projects

in Cables & Accessories

For the first time ever, long land-based transmission links are being implemented with extruded cable systems at a nominal voltage of ±525 kV. Read More >
Applying Sheath Voltage Limiters to Protect HV Power Cables

in Arresters, Cables & Accessories, Utility Practice & Experience

If segmentation is used to interrupt induced sheath current, measures must be taken to limit voltage induced on the sheath during transient events. Read More >
