Abstract
A diagnostic process for a cabling of a three phase motor in a 'delta-inside' configuration with a soft starter to a three phases power supply including, after cabling a soft starter with the thyristor outputs of the soft starter to the motor windings inputs, cabling the motor windings outputs to the main phases and powering the power supply or prior to startup of the motor, at least a test process including: measuring with voltage sensors, connected to the Mains inputs, voltage sensors connected to the motor outputs of the thyristors of the soft starter and observer functions within the soft starter the frequency, voltage and phase angle of the Mains and motor lines in order to compare such voltages and phases without triggering the thyristors; calculating the differential angle Δθ between the motor electric rotation angle θand the Mains rotation angle θ; comparing the calculated differential angle Δθ with known differential angles corresponding to a correct cabling differential angle and faulty cablings differential angles in test process steps to determine the status of the cabling, and wherein a result of the test process steps is displayed to show the status of the cabling.
