Determining the absence of voltage in medium voltage switchgears is performed in a set consisting of capacitive insulators, coaxial cables, and voltage indicating systems either with or without a relay. Capacitive indicating systems from KUVAG satisfy the demand for a favorably priced and maintenance-free system that complies with international standards, e.g., IEC 61243-5. Many systems and accessories ensure an ideal fit for virtually any customer application. In addition, KUVAG is positioned to custom-design unique systems in case very specific features are required.
