Transformer Turn Ratio Meter (DG-TTE-614)

Unique Id : DG-TTE-614 Categories: ,

TRANSFORMER TURN RATIO METER (DG-TTE-614), is designed for measuring actual turn ratio of power and distribution transformers. The instrument uses null balancing method for measurement to achieve high accuracy. The instrument is electronically protected for overload and short-circuit.

A current meter is provided to indicate the exciting current, taken by the transformer under test. A voltmeter is provided to indicate the excitation voltage given to LT winding of transformer under test. The instrument is supplied in wooden cabinet kept inside a leather carrying case along with a soldier carrying strap. The instrument is of heavy duty class, rated for continuous use. The unit is hand operated and requires no power source. It is designed to work satisfactory in normal climatic conditions of India.
