High Voltage Transformers
What is a high voltage transformer?
Transformers are normally
used in high voltage laboratory for testing purpose. This transformer is
subjected to transient voltages and surges. To withstand these impulse
voltages, the insulation of transformer is carefully designed. This type of
transformer is generally oil immersed. The high voltage transformers used for
HT cable testing purpose are to supply also sufficient electric current and
that is why the cooling system of these transformers is very carefully
Up to voltage 500 KV, generally single unit of high voltage transformer is used. But for higher voltage rating more than one transformer, are connected in cascade to produce required high voltage
Open and dry type
Primary (normally high voltage) winding on inner side and thin wires with high resistance.
Secondary (normally low voltage) winding normally on inner side with very low resistance.
Power range: 4KVA-10KVA
Voltage range: Any input and output voltage
Frequency range: 50Hz, 60Hz, 50/60Hz & 400Hz
a. High voltage transformer are used for general high voltage circuits, weapons, health, neon signs and many other high voltage circuits.
Open and enclosed transformers with different IP ratings and mounting are available.
