Transformer running at 30% Output. The next vid should have been 60% or full power, however, the wiring has bubbled over in the house, no more transformer ! Shame I did not get that on camera!

At first it looks like Texas is being attacked from the sky. Dozens of fluorescent explosions sweep through the night in bursts of bright blue, orange and green flashes. But the mysterious scene was actually caused by large numbers of electrical transformers exploding during a recent lightning storm in Fort Worth. A stunned resident recorded the amazing sight on Tuesday evening as most of the rest of the enormous city was plunged into darkness. The clip shows a large number of magnificent flashes stretching into the night sky. But viewers who see the video for the first time could be forgiven for believing that an immense nuclear battle was underway. The scenes would be equally at home in a Star Wars movie depicting a fierce light-sabre showdown in outer space. But experts came forward after the storm to point out that the explosions were caused by electrical transformers exploding. Transformers are found around the US for passing electrical energy from one circuit to another. They allow electrical voltage to be increased as it travels across a city through long distances of wires or cabling. During a storm, lightning strikes cause a surge in electricity along the lines. The transformers cannot handle this and explode. The video of the explosions has now become popular on the video-sharing website YouTube. One user wrote: 'Wow, that's impressive. It looks like a light show from a concert.' Video by :BrianLuenser Please check his channel out

Rating & Selection Of Power Voltage Transformers

!: Rating & Selection Of Power Voltage Transformers

Rating a Transformer

While making a choice for the transformer, more than just turns ratio must be considered. Such other determinants include voltage, current and power handling capabilities of primary and secondary windings.

The maximum voltage that can be applied to a winding depends upon the type and thickness of the insulation. Better and thicker will be the insulation, higher will be capacity of the voltage rating.

The current carrying capacity of the transformer can be determined by measuring the diameter of the wire used for winding. If the current exceeds the capacity, there will be overload resulting in loss of the current in the form of heat.

This dissipated heat can break the insulation, causing the wire to break down. And thus the transformer may be permanently damaged.

The capacity of voltage transformers mainly depend upon its ability to dissipate heat. If excessive heat can properly be removed, the current carrying capacity of transformer can be substantially increased. This power-handling capacity of the transformer can be measured in either volt ampere unit or the watt unit.

Selection of right Voltage Power Transformers

Some of the major factor that should be considered while selecting the transformer for your power applications are as follows:

The transformer should be capable of handling the expected loads (Also some amount of overload in emergency) Always check, if there is a possibility of increasing the load carrying capacity of the transformer. The investment and decision made should be based on certain life expectancy. Also consider the operational and installation cost beforehand to finalize your budget.
