How are voltage dip generators useful for voltage interruption test

Defining Voltage dip generator NEMA MG1-16.48 defines voltage dip as the greatest voltage difference from the rated generator output voltage. Inrush currents at motor start-up or large block loads limit engine speed and lower excitation to the main field generate these dips. Because the causes and solutions for instantaneous voltage dips differ from those for block loads, they are measured and ana...
