Application of Biodegradable Fluids as Liquid Insulation for Distribution and Power Transformers-1
For over 100 years mineral oil has been used as liquid insulation for power and distribution transformers. Transformer liquid insulation accomplishes a double mission acting as dielectric material, providing electrical insulation between regions of the transformer at different voltage levels, and as a cooling agent...

Understanding Current & Voltage Harmonics – 2
How do Current & Voltage Harmonics Affect the System? Current harmonics increase the rms current flowing in the circuit and thereby, increase the power losses. Current harmonics affect the entire distribution all the way down to the loads. They may cause increased eddy current and...

Understanding Current & Voltage Harmonics – 1
Current and voltage harmonics are often used interchangeably. In most places, only harmonics are quoted and whether the values pertain to current or voltage is not mentioned. The differentiation can be done on the basis of their origin. Understanding Total Harmonic Distortion The current and...

What Is The Enameled Wire Application?
Wire enamels are applied on copper and aluminium round and flat wires used in motors, transformers, generators and electrical measuring instruments. They are cured onto the wires with heat. The resulting coating’s main function is electrical insulation. Wires Insulated by Enamel Enameled wires are applied...

Wire Flattening Process
Wire flattening is an optimization method for round wire transformer designs. Wire flattening allows you to increase the filling factor on the layer by minimizing the gaps between round wires, resulting in lower-diameter, compact transformers. Below you can see a 1448 micron diameter copper conductor...
