ECOTAP VPD I, Single-phase On-Load Tap-Changer for Voltage Regulating Distribution Transformers (VRDT)

The smallest high-speed resistance type tap-changer in the world, made for single-phase applications. The ECOTAP VPD can be easily integrated in pole or pad-mount distribution transformers, offers a wide regulation range and is maintenance-free for the transformer lifetime. Deploying VRDTs – with similar footprint as traditional transformers – multiplies grid hosting capacity, supports CVR programs and often avoids costly re-conductoring.
