Estimation of Very Fast Transient Voltage Distribution in air-cored Pulsed Transformer Windings Based on FDTD Method
To study the voltage distribution in transformer windings under VFTO, a model for transformer windings has been developed based on Multi-conductor Transmission-Lines (MTLs) theory and the computing equations of the model based on FiniteDifference Time-Domain method (FDTD) is deduced. The Vector Fitting method is adopted to treat the frequency-dependent parameter by expanding the time-domain for...
متن کاملVoltage Distribution of Internal Windings of Pole-Mounted Distribution Transformer by Lightning Surge and Measures for Voltage Reduction
When steep lightning surge enters a pole-mounted distribution transformer, the voltage distribution of the internal windings is unbalanced. It is known that a layer-to-layer short or a turn-to-turn short occurs where the voltage distribution of windings is high. In this paper, the voltage distribution of the windings was measured at the primary and secondary sides of the transformer using a tes...
متن کاملAnalysis of the Voltage Stresses on Transformer Windings under Different Type of Surges
Standard high voltage lightning and switching impulse tests are performed on Extra High Voltage (EHV) transformers during manufacture to ascertain the breakdown strength of insulation used. But during their service, transformers encounter numerous voltage transients of complex and varying wave shapes which do not necessarily resemble these standard surge type voltages. This paper reports the re...
متن کاملSF6 High Voltage Circuit Breaker Contact Systems Under Lightning Impulse and Very Fast Transient Voltage Stress
In the past few years gas insulated high voltage circuit breakers have improved considerably, in particular with respect to required drive energy for operation, compactness and reliability. A further reduction in size implies increasing operational field stress inside the breaker and, thus, a reduction in built-in safety margins. If the design comes closer to its physical limits, in particular ...
متن کاملTransient Overvoltages in Power System
There are many reasons for over voltages in power system. The overvoltage causes number of effect in the power system. It may cause insulation failure of the equipments, malfunction of the equipments. Overvoltage can cause damage to components connected to the power supply and lead to insulation failure, damage to electronic components, heating, flashovers, etc. Over voltages occur in a system ...
