Impact & Mitigation of Icing on Power Network Equipment
In many parts of the world, ice and snow accretion on network equipment such as conductors, ground wires and insulators are a great concern for power system operators …
2020 Claude de Tourreil Memorial Award for Lifetime Achievement in Electrical Insulators
March will mark 15 years since the passing of one of the most important contributors to the development and application of composite insulator technology – Claude de Tourreil.
Testing & Designing Station Post Insulators for Performance Under Icing
Pollution exposure, ice and snow are all ambient factors impacting the dielectric reliability of post insulators in air-insulated substations, especially for HVDC. This exposure also affects equipment that employs post insulators…
Research & Experience with Coatings on Glass Insulators & Conductors (Video)
Environmental stresses on overhead lines can heavily impact overall system performance. For example, high levels of surface contamination due to salt deposits…
Damped AC for Commissioning & Diagnostic Testing of HV Cable Circuits
Current IEC standards for power cable systems up to and above 150 kV rated voltage are manufacturer standards and, according to experts, do not necessarily provide adequate recommendations for testing after-installation.
Super-Hydrophobic Silicone for High Voltage Insulators
Numerous problems have been reported due to pollution deposition on the surface of high voltage outdoor insulators. Although accumulation of pollution is typically most severe in coastal and desert areas…
Porcelain Insulators Under Cyclic Loading (Video)
Porcelain insulators have been used in electrical systems for over 120 years but designs have changed as these became proportionately greater in height with increased voltage requirements.
Field & Laboratory Assessment of RTV-Coated Insulators in Harsh Desert Environments (Video)
In spite of lack of international standards and limited field studies dealing with high voltage insulators coatings (HVIC), the past decade has seen sharp growth in interest among utilities worldwide.
