Solid insulation drying of 110 kV paper-oil instrument transformersInfluence of moisture on the instrument transformers' paper-oil insulation and its further maintenance is described in this paper. Improved insulation drying method using vacuum and temperature regulation with definite regulation algorithm of parameters is proposed and analyzed by comparing it with conventional drying method.

Abstract ALLOY 48 is a vacuum-melted, 48% nickel-iron alloy designed for high permeability, and low core losses. It is ideal in applications requiring efficient magnetic core materials, such as audio and instrument transformers, instrument relays, and many other communication equipment devices. It is excellent for rotor and stator laminations, and is also a very effective magnetic shielding material. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Fe-52. Producer or source: Magnetics Specialty Metals Division.
