Precautions and Control Points for Current Transformer Replacement

VIEW MORE

The specific process of current transformer (CT) replacement includes the removal of old transformers and related secondary cables, the installation of new transformers and the connection of secondary cables, etc. Due to the change of the secondary circuit of the current involved in the replacement

Working principle and application of power capacitor

VIEW MORE

Power capacitors, capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium form a capacitor. The size of the capacitance of the capacitor is determined by its geometric size and the characteristics of the insulating medium between the two

Reactive Power Compensation Scheme of Tuning Reactor

VIEW MORE

Reactors must be used in conjunction with capacitor banks to perform power factor correction for systems with a large number of nonlinear loads that generate harmonics.The capacitor and reactor configuration is tuned in a series resonant circuit such that the series resonant frequency is lower than

Effect of Altitude on Electrical Products

VIEW MORE

As the altitude increases, the pressure of the atmosphere decreases, and the air density and humidity decrease accordingly, which is characterized by:a. Low air pressure or air density;b. The air temperature is low and the temperature changes greatly;c. The absolute humidity of the air is small;d. T
