Pollution Flashover Behaviour of Hydrophobic, Hydrophilic & Partly Hydrophobic Coated Glass Insulators

Applying a silicone coating to ceramic insulators is an established technology to improve wet insulation behaviour under pollution due to the added hydrophobicity, which is also transferred to the pollution layer. Read More >

Impact & Management of Biofouling on HV Bushings

Although the topic of biofilm formation on ceramic and polymeric outdoor insulation has been widely addressed in the literature, up to now there has never been direct comparison between different materials under identical conditions. Read More >

Unique INMR Photos from 30+ Years & The ‘Back Stories’

in Insulators

Since its founding 33-years ago, INMR has covered power line and substation projects on all continents and toured hundreds of factories for electrical equipment as well as most high voltage and high power laboratories worldwide. Read More >
When to Remove an Arrester from Service

in Arresters

Deciding ‘end of life’ of an arrester can prove highly subjective since this component can survive for long periods with no obvious loss of function. Read More >
Surge Protection of Substations

in Utility Practice & Experience

While protecting substations from lightning and switching surges that lead to insulation flashover has been a key issue for as long as there have been power systems, options on how best to mitigate high voltage stresses have changed substantially. Read More >
Dielectric Frequency Response to Diagnose Condition of Bushings

in Bushings, Maintenance

It is important that all maintenance programs include bushing condition assessment since a problem with even a single bushing can prevent a transformer/reactor from returning to service. 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 >
Interchanging Traditional MV Porcelain Bushings with Composite Polymeric Types

in Bushings

Replacement or retrofit of medium voltage bushings is common practice after decades operating a power transformer. Read More >
Technical Review of RTV Insulator Coatings

in Insulators

Different maintenance practices have been developed for HV insulators operating in polluted environments. Read More >
Bird Hazards to Transmission Lines

in Wildlife Protection

Birds present a persistent threat to the safe operation of overhead transmission lines and are a significant factor behind line tripping. Read More >
Composite Insulating Cross-Arms for 400 kV Lattice Towers

in Utility Practice & Experience

A great deal of research has been devoted to finding tower designs that utilize composite cross-arms to replace insulators as well as traditional steel cross-arms. Read More >
