Transformer TIOG-250 is designed for use as part of cable test vans, so its' structure is resistant to vibrations and varying climatic factors. The transformer is virtually maintenance free.
The standard transformer power output is -- kVA.
Additionally, the transformer is capable of accommodating a built-in high voltage sulphur hexafluoride capacitor (or two, if required), which, if connected to the appropriate measuring apparatus, allows testing the capacitance of various insulators Cx, dissipation factors tgδ and partial conductive discharges.
The transformer also features an inductive voltage divider (bleeder), which allows measuring high voltage, passed on to the object under the test by the transformer.
