Abstract Arrester is used to protect various electrical equipment in the power system from lightning overvoltage, working frequency transient overvoltage impact and damage. Zinc oxide arrester widely system. Creepage distance a necessary item of performance test. It project for factory testing centralized network access testing. At present, measurement creepage mainly adopts artificial method p...

-External insulation is one of the critical aspects in the HVDC equipments and converter station design. Especially for UHVDC converter stations, the long creepage and clearance required has significant impact on the equipment and station design. The external insulation design of DC yard, valve hall, and for converter valves is presented. It is the intention of this report to review and summari...

This work attempts to apply an artificial neural network in order to estimate the critical flashover voltage on polluted insulators. The artificial eural network uses as input variables the following characteristics of the insulator: diameter, height, creepage distance, form factor and equivalent alt deposit density, and estimates the critical flashover voltage. The data used to train the netwo...

The tangential contact forces that arise at the interface between the wheel of a railway vehicle and the rail provide all the traction, braking, and guidance required by the vehicle. These forces are the result of microslip or creepage and can become unstable exciting vibration of the wheel, particularly at frequencies corresponding to the wheel’s axial (and radial) modes. Although theories exi...
