The KIT DUAL-GR is Zensol’s advanced solution for performing circuit breaker timing tests while maintaining both sides of the breaker safely grounded, engineered for professionals who demand maximum safety, measurement accuracy, and operational efficiency in breaker diagnostics.

Traditional breaker timing tests often require the removal of one side of the protective grounds. The KIT DUAL-GR is built on external flux transducers clamped around breaker contacts to detect current flow, allowing timing measurements without removing safety grounds. This approach eliminates electrical risks while providing precise and reliable timing data under all
field conditions.

By separating the measurement sensors from the current injection and keeping the breaker grounded, the KIT DUAL-GR ensures accurate detection of contact opening and closing times without interference, induced voltages, or the need for direct electrical connections across contacts.

Unlike conventional methods that rely on voltage measurements or intrusive wiring, the flux-based sensing system provides clean, repeatable, and interference-free measurements, adaptable to all HV, MV, and LV breakers.

Designed for real-world substation conditions, the KIT DUAL-GR features a modular, lightweight, and flexible architecture that allows rapid installation and alignment with breaker contacts, even in tight or complex configurations. Rugged construction ensures reliable operation in harsh field environments, while the workflow is optimized for engineers and technicians to maximize safety, speed, and measurement fidelity. By prioritizing external sensing, full grounding, and precise current detection, the KIT DUAL-GR delivers accurate and consistent breaker timing measurements without compromising safety or operational efficiency.
