However‚ transformer loads are increasing and reserved capacities are decreasing. Consequently‚ it is imperative to have some simple and practical means of assessing the insulation integrity of high voltage power transformers. Historically‚ diagnostic tests include dc resistance and ac dielectric loss of the winding insulation. The electric strength and moisture content of the oil are also measured. When a fault occurs samples of oil are sent to a laboratory for dissolved gas analysis (DGA). This

Abstract Electrical cables are the major arteries for electrical power. The power utilities are facing new challenges due to liberalization of electricity. It means reliability demand on distribution network is increasing day by day. The distribution networks are mainly cable networks of different voltage grade and dielectrics. Therefore‚ the proof design of cables is required after installations. During installation the wear and tear of the cables are must due to mechanical and environmental

we had foam roof insulation installed instead of replacing our conventional roof‚ our problems were solved. We didn’t know about spray roof insulation until we saw it being applied to a business in our town. We were able to talk with the business owner who told us why he had chosen to have an SPF or sprayed in place polyurethane foam roofing system installed. Like us‚ he had many issues with a flat roof. He said after much investigation he decided on using foam roof insulation due to it’s insulative
