In the method, AC current values of all three phases and DC current values are measured and evaluated at a frequency that is higher than the clock frequency of the inverter. An AC short-circuit current is also identified by subtracting the fundamental wave from the AC current sensor values. An AC component of the DC current sensor value is also identified, and it is identified whether this component is higher than a value predefined for regular operation. The AC short-circuit current and the AC component of the DC current sensor value are also compared. A short circuit is identified for the phase if the two values of the AC short-circuit current and the AC component of the DC current sensor value are approximately equal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Identification of a phase-to-ground inverter short circuit","description":"Arrangements and methods for identifying a phase-to-ground inverter short circuit in an IT (isolé-terre or isolated ground) network are provided.
