Our non-contact voltage measurement technology, which allows voltage to be measured with less risk, is helping spur efforts to measure power safely at facilities such as plants and buildings so that energy can be saved.

It’s typical in power measurement to use a clamp-on power meter. Although current is measured using conventional clamp sensors that can make measurements safely from outside wire insulation, voltage is typically measured by placing clips in contact with metal terminals such as circuit breakers. This approach poses the risk of a short-circuit if a metal clip inadvertently makes contact with the adjacent metal terminal, or electric shock if the worker accidentally touches a metal terminal.

Hioki products use no-metal-contact technology to measure current, voltage, and power, dramatically increasing the safety of measurement personnel.
