1. Since there are multiple harmonics in power grid and load, the additional harmonic current component will be produced in the isolation transformer coil. When the current component is high enough, the isolation transformer will be subjected to overload running, thus reducing the service life of transformer, even making it burnt out in a short time. 2. Since the K-coefficient isolation transformer is designed with full consideration in the non-linear load and the influence of harmonics on transformer performance, its reliable operation can be ensured.
