Excessive core loss of electrical steel is a common quality problem for transformer cores. Unqualified iron loss parameters will trigger a series of adverse effects on transformer operation and service life. First, excessive core loss increases transformer no-load power consumption. No-load loss exists continuously after equipment power-on. High iron loss causes long-term invalid energy consumption.
