Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price

The Basics of Partial Discharge Testing - HV Technologies

What Is Partial discharge?Typical PD Measurement CircuitsWhat Parameters Are Typically Measured During A PD Test?The Different Types of PD Measurement TechnologiesWhen speaking of partial discharge, the most important standard that every expert will refer to is IEC 60270: High-voltage test techniques – Partial discharge measurements. This standard applies to the measurement of PD in electrical apparatus or systems when testing with AC voltage up to 400 Hz or with DC voltage. In this blog post we will focus on measuring PD by applying AC voltages. IEC 60270 defines the term “partial discharge” as: In general PD occurs in areas of the insulation or on the surface of the insulation that is subjected to higher local electric field stress concentrations, such as in a cavity in a solid dielectric, a sharp protrusion, or in low density regions of a liquid dielectric. PD initiates once the electric field is high enough, or the mean-free path is short enough, to cause impact ionization to create a “streamer”, otherwise known as an electron avalanche. Furthermore, a free electron must be present in order to start the discharge process, which can be gen...Get price
