Signatures of Transient Overvoltages in Low Voltage Power Systems in Tea Factories and Their Implications on Insulation Deterioration and Allied Power Quality Issues

<div>Transient voltages in the form of impulsive inductive kicks with the steep front which follows oscillatory damps. (a) For a motor with Star-Delta starter, transient spears out at conversion. (b) For a motor with direct online starter.</div>
