Causes of Insulation Deterioration

Heat is the prime cause which leads to electrical insulation deterioration. Some possible causes of heat generation in the electrical insulation are as follows: Heat is generated in the electrically stressed insulation, due to dielectric loss and conduction currents. Heat is imparted to insulation by...

Working Principle of Petersen Coil

To better understand the working principle and need of Petersen Coil, let us have a look at the arcing ground phenomenon. We know that arcing ground phenomenon is observed in ungrounded 3 phase system. During arcing ground the voltage of healthy phase rises from phase...

ABCD Parameters of Transmission Line

ABCD parameters are generalized parameters of transmission line. These parameters are quite helpful for calculation and analysis of transmission line. In any four terminal network, the input voltage and current can be expressed in terms of output voltage and current provided the network should be...
