Wiring Methods and Parameters of Grounding TransformersGrounding Transformer Winding ConfigurationsGrounding transformers are classified by winding connection into two types: ZNyn (zigzag) or YNd. Their neutral points can be connected to an arc suppression coil or a grounding resistor. Currently, the zigzag (Z-type) grounding transformer connected via an arc suppression coil or a low-value resistor is more commonly used.1. Z-Type Grounding TransformerZ-type grounding transformers come in both oil-immersed and dry-type insulation versions. Among them12/05/2025 -
Why Do We Need a Grounding Transformer and Where Is It Used?Why Do We Need a Grounding Transformer?The grounding transformer is one of the most important devices in power systems, primarily used to connect or isolate the system neutral point to ground, thereby ensuring the safety and reliability of the power system. Below are several reasons why we need grounding transformers: Prevent Electrical Accidents:During the operation of a power system, abnormal conditions such as voltage leakage may occur in equipment or lines due to various reasons.

How to Implement Transformer Gap Protection & Standard Shutdown StepsHow to Implement Transformer Neutral Grounding Gap Protection Measures?In a certain power grid, when a single-phase ground fault occurs on a power supply line, both the transformer neutral grounding gap protection and the power supply line protection operate simultaneously, causing an outage of an otherwise healthy transformer. The main reason is that during a system single-phase ground fault, the zero-sequence overvoltage causes the transformer neutral grounding gap to break down. The resulting12/05/2025 -
