JOSLYN HI-VOLTAGE® CAPACITOR SWITCHES
Dependable switching for efficient grid performance.
ENGINEERED TO MEET THE DEMANDS OF MODERN POWER SYSTEMS
ABB's Joslyn Hi‑Voltage capacitor switches help keep utility systems running efficiently and reliably. The environmentally friendly switches are free of oil or gas, eliminating most regulatory requirements for monitoring usage and leakage for a long-lasting, virtually maintenance-free service life.
KEY FEATURES AND BENEFITS
<p>Available in VerSaVac™ (VSV) distribution and Varmaster (VBM) substation configurations, these switches serve a broad range of voltage and current requirements. A zero voltage closing (ZVC) control helps protect the broader system by reducing voltage spikes and inrush current during switching.</p>
Continuous operation
<p>Switches capacitor banks for improved system efficiency, voltage profile and capacity.</p>Reliable
<p>Vacuum interruption, solid dielectric insulation and solenoid operators help offer a long, reliable service life of up to 100,000 expected operations with virtually no required maintenance.</p>Environmentally responsible
<p>Built with no oil or gas, eliminating most regulatory requirements for monitoring usage and leakage.</p>INDUSTRIES WE SUPPORT
