Product Description
Lighting is a common phenomenon in transmission lines because of their tall height. This lightning stroke on the line conductor causes impulse voltage. The terminal equipment of transmission line such as power transformer then experiences this lightning impulse voltages. Again during all kind of online switching operation in the system, there will be switching impulses occur in the network. The magnitude of the switching impulses may be about 3.5 times the system voltage. Insulation is one of the most important constituents of a transformer. Any weakness in the insulation may cause failure of transformer. To ensure the effectiveness of the insulation system of a transformer, it must confirms the dielectric test. But the power frequency withstand test alone can not be adequate to demonstrate the dielectric strength of a transformer. That is why impulse test of transformer performed on it. Both lightning impulse test and switching impulse test are included in this category of testing.
* Front of wave
establish a minimum impulse dielectric strength of a transformer.
If lighting disturbance travels some distance along the transmission line before it reaches the transformer, its wave shape may approach to full wave. If during traveling, if flash-over occurs at any insulator of the transmission line, after the peak of the wave has been reached, the wave may become in form of chopped wave.
The effect of these waveforms on the transformer insulation may be different from each other. We are not going here in detail discussion of what type of impulse voltage waveforms causes what type of failure in the transformer. But whatever may be the shape of lightning disturbance voltage wave, all of them can cause insulation failure in the transformer. So lighting impulse test of transformer is one of the most important type test of transformer.
