In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it.

This standards collection addresses product development, performance, compatibility and related topics in order to ensure product compatibility and environmental safety.

Bushing Test Methods The most common testing done on bushings in the field involves measuring capacitance and dielectric loss at voltages up to 10 kV (i.e. Doble testing). There are also systems available that will do this measurement on-line at operating voltage.

Function: Electrical insulators are used to provide insulation and support to electrical components and equipment, while electrical bushings are used to provide a pathway for conductors or cables to enter or exit an electrical enclosure while maintaining electrical isolation.

IEC 61508 allows for the development of a uniform technical approach that can be applied to all safety systems in electronics and related software. It is a horizontal standard applicable across a wide range of sectors. The standard requires the analysis of the potential risks or hazards of a given system or device.

The two principal types of bushing construction are solid or bulk type and capacitance-graded (sometimes called condenser type). The bushings used for the low voltage winding(s) of a transformer are often solid type with a porcelain or epoxy insulator.
