ABB VIZ-11 INDOOR POTENTIAL TRANSFORMER (PT) T269548

The ABB VIZ-11 is a medium-voltage Indoor Potential Transformer (PT), also known as a Voltage Transformer. It is a critical component in metal-clad switchgear, used to step down high primary voltages (up to 15kV) to a safe secondary level (typically 120V) for metering, relaying, or control power. Constructed with a vacuum-cast polyurethane insulation, these units are designed to withstand significant electrical stress and are often found in "draw-out" configurations within industrial power distribution centers.
