1.Reasonable Use of TransformersTransformers should be selected with flexible winding configurations according to the power consumption characteristics of industrial enterprises, and load adjustments should be made promptly based on each transformer’s load rate to ensure operation at optimal loading conditions. Three-phase loads on transformers should be kept as balanced as possible; unbalanced operation not only reduces output capacity but also increases losses. Energy-efficient transformers sh

What Is Common Grounding?Common grounding refers to the practice where a system’s functional (working) grounding, equipment protective grounding, and lightning protection grounding share a single grounding electrode system. Alternatively, it may mean that grounding conductors from multiple electrical devices are connected together and linked to one or more common grounding electrodes.1. Advantages of Common Grounding Simpler system with fewer grounding conductors, making maintenance and inspecti

Basic Composition and Function of Circuit Breaker Failure ProtectionCircuit breaker failure protection refers to a protective scheme that operates when the relay protection of a faulty electrical device issues a trip command but the circuit breaker fails to operate. It uses the protection trip signal from the faulty equipment and the current measurement from the failed breaker to determine breaker failure. The protection can then isolate other relevant breakers within the same substation in a sh
