The definition of extra high voltage (EHV) again depends on context.
Both come with a side of potato salad given extra voltage with minced jalapeno pepper.
This allows headphones of a low sensitivity to be driven louder as a result of the extra voltage provided by the amplifier.
To account for this, a phase fired control must be able to provide some degree of extra voltage to draw the same heating current through the element.
A selection element can be added to improve the situation, but this selection element consumes extra voltage and power.
In Zone 1, only separated extra low voltage (SELV) devices are permitted.
Voltages above 230 kV are considered extra high voltage and require different designs compared to equipment used at lower voltages.
Both of these methods have a parallel circuit design - the extra voltage is fed away from the standard path to another circuit.
When voltage is too high, an MOV can conduct a lot of current to eliminate the extra voltage.
It reduces corona discharge loss at extra high voltage (EHV) and interference with communication systems.
