Table of Contents Learn more about split core current transformer With the development of digital substations and smart grids, electrical current transformers have been widely used, mainly in the measurement, protection and monitoring of power systems. Current transformers are widely used to convert a high voltage current input and produce a proportional low voltage, low current signal…
In google trends, energy monitors and home energy metering devices have been stable and increasing since Jan 2015 in USA. Most people have considered investing in energy efficient appliances, switching to LED lightbulbs, and installing a programmable thermostat to save energy. Home energy monitors connect to a mobile and allow you to turn them on/off when you are…
Generally, there are four types of leakage currents: semiconductor component leakage current, power supply leakage current, capacitor leakage current and filter leakage current 1. Leakage current of semiconductor components The very small current that flows through the PN junction when it is turned off. D-S is forward biased, G-S is reverse biased, and after the…
As the world’s largest consumer of new energy electric vehicles, new energy electric vehicles are developing rapidly, and the safety of electric vehicle charging piles is a top priority: whether the electric vehicle charging pile can avoid random plugging and unplugging during the charging process. The accident caused by the charging gun, whether it can…
