Can I read MiCOM P543 Bias Characteristic Testing on EtoBox?

MiCOM P543 Bias Characteristic Testing by Ravi Mehroliya is a document available to read on EtoBox.

What is MiCOM P543 Bias Characteristic Testing about?

The document discusses testing the bias characteristic of a MiCOM P543 relay. It shows the current differential principle where the differential current is the sum of the currents from relay A and B. If the currents are equal, there is no fault. It then shows test results plotting differential current against bias current and sample waveforms. It discusses how the relay measures current using Fourier filtering and provides sample measurements. Finally, it discusses how saturation of current transformers can
