The basis for the nondestructive testing of insulation

Electrical Engineering, 1941
DIELECTRIC strength is the property of insulation that is most important to the operating power companies. The factor of safety determined by the ratio of breakdown voltage to operating voltage must be maintained. Yet this breakdown voltage cannot be measured on a finished piece of insulation.

Testing of insulators

1988
In this chapter, attention is largely concentrated on predictive tests, aimed at determination of orders of merit, in ability to operate under contamination and at those made for purposes of research into insulator behaviour. Natural and artificial tests are covered separately.

Radiation Effects in Advanced Multiple Gate and Silicon-on-Insulator Transistors

IEEE Transactions on Nuclear Science, 2013
The aim of this review paper is to describe in a comprehensive manner the current understanding of the radiation response of state-of-the-art Silicon-on-Insulator (SOI) and FinFET CMOS technologies. Total Ionizing Dose (TID) response, heavy-ion microdose

Routine Insulation Testing of Synchronous Machines

Transactions of the American Institute of Electrical Engineers, 1951
THE CONTINUOUS operation of large synchronous machines and freedom from failures in service is of vital interest to every electric utility company. One of the major causes of unpredicted and unscheduled outage is the failure of stator coil insulation.

Understanding stator insulation in-process testing

2015 61st IEEE Pulp and Paper Industry Conference (PPIC), 2015
Modern day manufacturing practices are focusing on maximizing production while actively pursuing ways to mitigate potential failures in their products. With rotating machinery, part of this pursuit requires qualification checkpoints during manufacturing processes. For motor stators, it is essential to perform in-process insulation testing to ensure the

Nondestructive testing of insulation

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1953
THE USER of electrical apparatus is constantly in need of information concerning the condition of the insulation. This information, at the present time, is supplied by such tests as insulation resistance, power factor, capacitance, or by more severe tests such as ?high-pot.? Unfortunately, none of these tests give a true indication of the ?health?

The testing of high-voltage line insulators

Proceedings of the American Institute of Electrical Engineers, 1908
The specification herein proposed as standard for the testing of high-voltage line insulators was written at the request of the chairman of the High Tension Transmission Committee in order to bring this matter before the Institute for discussion. It is not presented as representing the writer's personal opinion so much as an endeavor to harmonize ...

Thermal Insulation Test of RCCW with Inner Insulating Layer

Advanced Materials Research, 2010
To improve the durability of external thermal insulation plate on walls, the new reinforced concrete composite wall(RCCW) with inner insulating layer of polystyrene panel was developed. The paper introduces the thermal insulation tests of the RCCWs by the protection chest method, and studies the method for eliminating the effect of heat-bridge on the ...
