This document presents a structured methodology for calculating reactive compensation capacity (kvar) required for power factor correction in electrical distribution systems. Three principal techniques are detailed:1.​Precision Calculation Method​ (Recommended); 2.Energy-Meter Derived Averaging Method; ​3.Transformer-Based Empirical Estimation. Read More

I. Definition: The Reactive Power SolutionA capacitor bank (often called a Reactive Power Compensation Unit) is a crucial device for optimizing power supplies and overall electrical system efficiency. Manufactured to the stringent International Electrotechnical Commission standard IEC 62271, it cons Read More

What is the significance of the switchgear?Medium-voltage switchgear generally refers to the range of 10KV to 35KV, and is generally used in power distribution systems. Low-voltage switchgears refer to 400V low-voltage switchgears, which are mainly power distribution in low-voltage systems. Read More

The Difference Between Ring Main Units and SwitchgearDefinitionRing Main Unit (RMU): An RMU is a device used in power distribution systems, primarily for distributing and protecting electricity. It is commonly utilized in urban distribution networks to enhance the reliability and flexibility of powe Read More
