The ZVS-300 DP is a high-voltage differential voltage probe designed for safe and accurate measurement of AC and DC voltage signals in circuit breaker diagnostic and testing applications. It enables the acquisition of high-potential voltage signals and converts them into a low-level output suitable for Zensol test systems and data acquisition equipment.
The probe is used to interface high-voltage points in circuit breaker control and auxiliary circuits with diagnostic instruments, ensuring safe signal acquisition during testing operations. It allows technicians to observe voltage waveforms and transient behavior without direct connection of measurement equipment to high-energy circuits.

During circuit breaker testing, the ZVS-300 DP is used to monitor voltage variations associated with control circuits, coil supply behavior, and switching sequences. It provides accurate signal representation for timing correlation between voltage events and mechanical operation of the breaker.

The differential measurement principle ensures that voltage differences between two points are captured reliably, making the probe suitable for noisy electrical environments typically found in substations and switchgear installations. This enables stable waveform recording even during fast switching and transient conditions.

The ZVS-300 DP integrates directly with Zensol acquisition systems such as CBA and CBV platforms, where measured signals are displayed and analyzed in dedicated software. This allows full synchronization of voltage waveforms with current, contact timing, and mechanical displacement measurements.

By combining high-voltage differential measurement capability with safe signal scaling and direct compatibility with Zensol diagnostic systems, the ZVS-300 DP provides a reliable solution for voltage waveform acquisition and transient analysis in high-voltage circuit breaker testing.
