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
