StandardInductive Dry – Type Nominal Voltage Transformer

These high accuracy Inductive Dry type voltage
transformers built with synthetic resin have been
designed to be used as a reference transformer for
voltage transformer measurement with Tettex or
another transformer measuring devices.

FEATURES AND BENEFITS

The transformer is equipped with different High voltage
resin isolated bars to modify the transformers ratio
(high Voltage winding), allowing a fast and easy
configuration of the nominal transformers.

Dry type, no isolating oil means no leakages

Highest accuracy in the market +0.005% + 0.5Min

Large measuring range 40%.....120%

Easy to work with, changing the ratio by plug and ply
a connector. No cable reconnection needed

Other output voltages can be supplied under request

APPLICATIONS

is mostly used by:
Manufacturer of current instrument transformers
Calibration laboratories
National Standards Laboratories
On-Site Testing of high voltage current instrument
transformers
