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

Dağıtım kutuları ve kabinlerinin kurulumunda dikkat edilmesi gereken birçok yasak ve sorunlu uygulama bulunmaktadır. Özellikle belirli bölgelerde, kurulum sırasında yapılan hatalı işlemler ciddi sonuçlara yol açabilir. Önlemler takip edilmeyen durumlarda, burada önceki hataları düzeltmek için bazı düzeltilme önlemleri de sunulmaktadır. Üreticilerin dağıtım kutuları ve kabinleri hakkında yaygın kurulum yasaklarına birlikte bakalım!1. Yasak: Aydınlatma dağıtım panelleri teslim alındığında denetlen

1. Induced Lightning OvervoltageInduced lightning overvoltage refers to the transient overvoltage generated on overhead distribution lines due to nearby lightning discharges, even when the line is not directly struck. When a lightning flash occurs in the vicinity, it induces a large amount of charge on the conductors—opposite in polarity to the charge in the thundercloud.Statistical data shows that lightning-related faults caused by induced overvoltages account for approximately 90% of total fau

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
