The VOG-11 is a compact outdoor voltage transformer designed for metering and power supply in 15 kV line-to-ground applications. Power supply applications may include secondary protection and control apparatus, such as controllers and other IEDs that can be found on other equipment (for example, reclosers).
The VOG-11 outdoor voltage transformer is designed for me-tering line-to-ground circuits. The single centered bushing and reduced neutral end insulation permit a significant reduction in size and installation spacing, while maintaining full 110 kV BIL insulation clearances.
The VOG are outdoor single-pole voltage transformers, cast in hydrophobic cycloaliphatic epoxy resine (HCEP), capable of withstanding outdoor environmental conditions. The HCEP material offers superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength.
The VOG-11 outdoor voltage transformer is designed for metering line-to-ground circuits. The single centered bushing and reduced neutral end insulation permit a significant reduction in size and installation spacing, while maintaining full 110 kV BIL insulation clearances.
The VOY-11 outdoor voltage transformer is designed for out-door metering applications. The primary and secondary coils are wound using special winding and shielding techniques for improved voltage stress distribution. The entire core and coil assembly is cast in polyure-thane under a vacuum.
