Sag in Overhead Conductor. Switchable Capacitor Bank or Switched Capacitor Bank. Ferranti Effect in Power System. MOSFET as a Switch. Why Supply Frequency 50 or 60 Hz not Other Values than these?. Electrical breakdown occurs when the electric field in the material is strong enough to accelerate free charge carriers (electrons and ions, which are always present at low concentrations) to a high enough velocity to knock electrons from atoms when they strike them, ionizing the atoms. Egg shaped strain insulator .

Please provide your valuable comments Name : - Email : - Location : - Your content : - . Flexible insulating materials such as PVC (polyvinyl chloride) are used to insulate the circuit and prevent human contact with a 'live' wire one having voltage of 600 volts or less. In older apparatus made up to the early 1970s, boards made of compressed asbestos may be found; while this is an adequate insulator at power frequencies, handling or repairs to asbestos material can release dangerous fibers into the air and must be carried cautiously. A perfect insulator does not exist, because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. High voltage insulators for outdoor use are shaped to maximise the length of the leakage path along the surface from one end to the other, called the creepage length, to minimise these leakage currents.[3] To accomplish this the surface is moulded into a series of corrugations or concentric disc shapes. Capacitor Bank Reactive Power Compensation. Class 2 insulation means that the device is double insulated.
