Standards Development
This document of IEC 63405 is applicable to the measurement of capacitance and dielectric loss at power frequency for electrical apparatus, components, or systems, with the highest voltage for equipment above 1 kV.
This document
- defines the terms used
- suggests methods of test
- suggests test object connections
- provides possible test procedures
- provides guidance on requirements of calibration
This document is primarily concerned with capacitance and dielectric loss measurements for electrical equipment, such as capacitors, cables, power transformers, bushings, switches, circuit breakers, and instrument transformers. The tests of insulation materials (solid, liquid, gas, etc.) or power electronics components are NOT included in this standard.
