How should a surge arrester with cracked or exploded porcelain housing be handled?Answer:Handling of Cracked Porcelain Housing:Under normal weather conditions, apply to the dispatcher to de-escalate and replace the damaged phase arrester with a qualified unit. If no spare parts are available, paint or epoxy resin may be applied to the crack to prevent moisture ingress, with replacement scheduled as soon as possible.During thunderstorms, avoid taking the arrester out of service if possible; defer

Methods for Handling Abnormalities and Accidents in Substations

1. What is accident handling? What are the common types of operations used in accident handling?Answer: Accident handling refers to a series of operational actions taken in response to an emergency that endangers personal, power grid, or equipment safety, or when a power grid or equipment accident occurs. The goal is to quickly rescue personnel, isolate faulty equipment, adjust operating modes, and restore normal operation as soon as possible.Common operation types include: test energizing, forc

How does an electrical substation work?

How does an electrical substation work?

An electrical substation is a critical component of the power transmission and distribution system. Its primary function is to receive electricity from high-voltage transmission lines and deliver it at lower voltages suitable for end users, such as homes, businesses, and other consumers. The operation of a substation can be summarized as follows:Step-down Transformer: Electricity generated at power plants is transmitted over long distances at high voltages to reduce energy losses.
