KOTEF
Oil-Insulated Combined CT/VT up to 420 kV
KOTEF utilizes the same components as the individual CTs and VTs. Both transformers are combined in a single metering unit and are available in porcelain or composite. The KOTEF combines the advantages and design features of the OSKF and OTEF lines.
Customer Benefits
- Excellent solution for adding metering capability to either a new substation installation or a site being upgraded where space is at a premium
 - Price advantage
 - Space saving - only one base
 - Cost savings on transportation and assembly
 - Maintenance free
 - Protection against bursting
 
Characteristics
- 72.5 to 420 kV
 - Oil expansion by stainless-steel diaphragm bellows
 - Oil level indicator
 - Secondary cores in aluminum box
 - Changing of primary ratio by primary series-parallel connection (double or triple ratio) or by secondary taps
 - Compliance with IEC and IEEE or equivalent standards
 - Paper oil insulation
