Voltage Distribution Over Suspension Insulator String Suspension Insulators: As the voltage level increases, pin-type insulators become very bulky and their cost also increases rapidly. Hence the most popular insulators used for very high voltage transmission lines are suspension-type insulators. These insulators have several porcelain disc units. These units are connected in series with the help […]

Testing of Power System Insulators The insulators are tested according to the standards. The following tests are performed while testing an insulator : These tests are further grouped into three classes according to the standards which are, Type tests: These tests are performed to judge the design and specified ratings of the insulator. These tests

In modern power systems, the power flow in the transmission lines can be controlled with the use of power electronics. The Flexible A.C. Transmission Systems (FACTS) give solutions to the problems and limitations that were introduced in the power system with the introduction of power electronics-based control for reactive power. The FACTS technology making use
