Grounding transformer is a special type of transformer primarily used for grounding protection in power systems. The design and winding connection methods of this transformer are crucial to ensuring the safe operation of power systems.1.Function of Grounding TransformerThe main function of a grounding transformer is to provide grounding protection in power systems. When a ground fault occurs in the system, the grounding transformer helps limit the fault current, thereby protecting equipment and

1. IntroductionA transformer operates based on the principle of electromagnetic induction. The main components of a transformer are the windings and the core. During operation, the windings serve as the path for electric current, while the core serves as the path for magnetic flux. When electrical energy is input to the primary winding, the alternating current creates an alternating magnetic field in the core (i.e., electrical energy is converted into magnetic field energy). Due to magnetic link

1. What is Secondary Equipment Grounding?Secondary equipment grounding refers to connecting the secondary equipment (such as relay protection and computer monitoring systems) in power plants and substations to the earth via dedicated conductors. Simply put, it establishes an equipotential bonding network, which is then connected to the station’s main grounding grid at multiple points.2. Why Does Secondary Equipment Require Grounding?Normal power-frequency currents and voltages during primary equ
