Taking the way of measuring the features of disturbance in time domain to analyze electromagnetic compatibility between electrical equipment including network

A method is presented for taking the changing time-domain curve for a current or voltage and comparing it with the time-domain impedance curve to assess electromagnetic compatibility between electrical equipment and networks. The method is suitable for use even when the harmonic source and/or impedance of the network is unstable. An example of its application to study a hoisting machine in a colliery is given
