The Voltage Presence Indicating System (VPIS) is a compact, energy-efficient device designed to indicate the presence of voltage in high-voltage switchgear and electrical systems. With individual LED indicators for each phase, built-in voltage-limiting protection, and IEC 62271-206 compliance, VPIS provides an essential layer of operational safety and diagnostic support for modern power systems.
