VRO ANSI — Instrument Transformers with ABB ResiVolt Technology

15-34.5 kV, outdoor, 110-200 kV BIL, 60 Hertz, Minimum operating temperature: -50 °C

Distribution networks continue to evolve due to increased instances of distributed energy resources (DER), EV charging, vacuum switching and the like. This creates a challenge for utilities, especially as these applications bring unintended changes to the network paradigm. The VRO-150G incorporates new and innovative technology, reflecting improvements designed and tested to overcome these disruptive network system challenges.

The electro-tin-plated primary H1 bushing terminal accommodates #10 to 250 MCM conductors. The H2 neutral terminal is insulated to withstand a 19 kV test level and can be disconnected from the external ground cable for power factor measurement.

Clamp-type secondary terminals accommodate#14 to #3 wire.

VRO transformers are available in hydrophobic cycloaliphatic epoxy (HCEP) insulating material.
