Test transformers / step-up transformers

EPRO Gallspach's test transformers are proven over decades and same as all other equipment they offer highest lifetimes of several decades.

What is a test transformer?

Test transformers / step-up transformers are used in various applications for generation of high voltage. Like EPRO standard voltage and current transformers, test transformers are used for example for accuracy measurement on current and voltage transformers, to generate high voltage or high current.

Where test transformers / step-up transformers are used?

Test Transformers are used in metrological institutes /national standard bodies, manufactures of voltage and current transformers, transformers, as well as at high voltage laboratories and everywhere a generation of high voltage is needed.

Which models are available?

Models from 20kV up to 500kV are available, with output power of 5kVA up to 100kVA. 
Detailed specifications will be established according to customer's requirements. 
For higher voltage they are designed in a cascade construction where the lower cascade step can be operated independently. Maximum reliability in the lab over decades is secured by the use of these maintenance free test transformers.
Epro Gallspach´s dry insulated test transformer are available from 20kV-30kV with a max. continuous output of 5kVA. The test transformer are very light weighted devices with a weight of 85-105kg. The devices are free from oil and therefore very environmental friendly.

Next to step-up transformers EPRO produces also Step-down transformers on customers demand.

Which frequencies are possible?

Normal operating frequencies are 50 to 100 Hz but also for special applications design for higher frequencies is possible, as well as for 16,66Hz. All test transformers are partial discharge free.
