TVI Series SF6 Inductive Voltage Transformer

Overview

TVI (Inductive Voltage Transformer) na da ake yi wa tarihi mai amfani da SF6 instrument transformers da inductive voltage transformers don PASS da GIS. Wannan TVI na da gas insulated inductive type of voltage transformer wanda ake kawo da shi don revenue metering da protection a hanyar high voltage networks. An sanya shi don cikin yadda ake gudanar da sauran alamomin sama, daga alamomin pola zuwa alamomin jangal. Amfani da composite insulator da pressure relief device ya ba shi da zama masu inganci da kyau a cikin yankunan da suka ci abubuwan jiragen.

Advantages

TVI, saboda amfani da gas SF6 da composite insulator, ta ba shi da sadarwa:
● highly reliable equipment
● explosion proof design
● maintenance free
● dielectric quality not depending on long treatments
● negligible level of partial discharge
● dielectric mean not subjected to ageing
● wide safety margin against saturation and ferro-resonance
● high seismic withstand capability
● suitable for applications in mobile substations
● higher performance in very heavy polluted environments
● available with a gas insulated disconnector for increased

Flexibility during operation

● Suitable for both metering and protection
● Magnetic cores made of laminated steel with oriented grain and a high level of permeability
● Windings made of electrolytic copper
● Primary winding connected directly to the high voltage side while the secondary winding supplies the low voltage panels
● Insulation system designed to guarantee a life cycle of 30 years. Declared maximum gas leakage: less than 0.1 % per year
● Safety margin for normal wind loads, stress from conductors and seismic forces
● Construction in conformity with national pressure standards
● Installed on a metal support with four eyebolts for lifting.
