National Field Services - Partial Discharge

Intro to Partial DischargeMany Possible CausesUltrasonic Testing For PDTransient Earth Voltage Phenomenon and TestingOne of the first indicators of insulation deterioration is what is called a Partial Discharge (PD). A PD is an electrical discharge or spark that bridges a small portion of the insulation between two conducting electrodes in medium- and high-voltage assets. The National Fire Protection Association (NFPA) says that the leading cause of electrical failures is breakdown of insulation. According to the IEEE Gold Book, Table 36, cables, switchgear and transformers are likely to endure the greatest losses from insulation failure.Get price

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

Difference Between High, Medium and Low Voltages | Generator

High voltages range from 115,000 to 230,000 VAC and Extra-High voltages range from 345,000 to 765,000 VAC. The United States transmits up to 500,000 volts on the high voltage grid. High voltages require specialized switching and distribution panels. The control rooms have redundant switching capabilities.Get price

High voltage substations overview (part 1) | EEP

Circuit ConfigurationProtective MeasuresArrangement and ModulesHigh voltage substationsare points in the power system where power can be pooled from generating sources, distributed and transformed, and delivered to the load points. Substations are interconnected with each other, so that the power system becomes a meshed network. This increases the reliability of the power supply system by providing alternate paths for flow of power to take care of any contingency, so that power delivery to the loads is maintained and the generators do not face any outage. The high voltage substation is critical component in the power system, and the reliability of the power system depends upon the substation. Therefore, the circuit configuration of the high voltage substation has to be selected carefully. Busbars are the part of the substation where all the power is concentrated from the incoming feeders, and distributed to the outgoing feeders. That means that the reliability of any high voltage substation depends on the reliability of the busbars present in t...Get price
