Abscense Detectro of Voltage – Hot Line Tester

Device used to detect the absence of voltage in alternating current (AC) systems, through audible and visual signals. The detection system operates by direct contact with the conductor, using a clamp-type connector.

It is applied during interventions in energized systems, such as Distribution Lines, Transmission Lines, Substations, and Compact Networks, to identify any unexpected de-energization. In such cases, electricians must strictly follow the safety procedures defined in the company’s work instructions.

In compliance with the requirements of the Regulatory Standard for Safety in Electrical Installations and Services NR-10 (item 10.5.1 – C – Verification of voltage absence), we offer models tested according to the ABNT NBR IEC 61243-1:2020 and the international standard IEC 61243:2021, specially designed for use at voltages above 1 kV AC.

These instruments are designed with an external compartment for battery replacement, ensuring safety during the replacement process without compromising the electronic board. They also feature a high degree of protection and sealing against temperature and humidity variations, as well as improvements in shielding, impact resistance, vibration, and weather resistance.
