Designed for demagnetizing large power transformers and current transformers after DC resistance testing and other DC experiments. Essential before transformer commissioning to prevent relay protection malfunctions, inrush current damage, and CT measurement inaccuracies. Ideal for utility substations, power plants, and transformer manufacturers, particularly for 110kV and above high-capacity transformers. Eliminates harmful residual magnetism that threatens grid stability and equipment safety.
