The OTCF capacitor voltage transformer is designed to meet industry standards (ANSI/IEEE or equivalent) using only high-quality materials to ensure operational security. Its robust and leak-proof structure allows for operation even in regions with hight seismic activities. It has a high-grade, paper-synthetic insulation system with a porcelain or composite insulator and an oil expansion mechanism thru its stainless steel bellows. The OTCF transformer has a thermal capacity of up to 1500 VA, a Un. of 72.5 to 765 kV (1100 kV), and a Cn. from 1750 to 37500 pF. It is virtually maintenance-free and can be easily transported and installed.
