Resonant Transformers: The equivalent circuit of a high voltage testing Resonant Transformers consists of the leakage reactance of the windings, the winding resistances, the magnetizing reactance, and the shunt capacitance…
Half and Full Wave Rectifier Circuits: Half and Full Wave Rectifier Circuits for producing high d.c. voltages from a.c. sources may be (a) Half wave, (b) Full wave, or (c) Voltage…
Use of Power Capacitor: In most of the industrial applications, the power requirements are reactive in nature and a lagging current is drawn from the power lines. This requires additional…
Solid Dielectrics Used in Practice: The majority of the insulating systems used in practice are solids. They can be broadly classified into three groups: organic materials, inorganic materials and synthetic…
Breakdown of Solid Dielectrics in Practice: There are certain types of breakdown which do not come under either intrinsic breakdown or thermal breakdown, but actually occur after prolonged operation. These…
Pure Liquids and Commercial Liquids: Pure liquids are those which are chemically pure and do not contain any other impurity even in traces of 1 in I09, and are structurally…
Gases and Gas Mixtures for Insulation Purposes: Over the years, considerable amount of work has been done to adopt a specific gas for practical use. Before adopting a particular gas…
Oil Circuit Breaker Diagram: In such Oil Circuit Breaker Diagram, some insulating oil (e.g., transformer oil) is used as an arc quenching medium. The contacts are opened under oil and…
