1. Time measurement: 12 fracture intrinsic points, closing time, with the same period, phase with the same period.
2. Reclosing measurement: each fracture closing - minute, minute - closing, minute - closing - minute process time, one minute time,one closing time, two closing time, gold short time, no current value.
3. Bounce measurement: closing bounce time, bounce times, bounce waveform of each fracture, rebound amplitude of each fracture.
4. Velocity measurement: stiffness, maximum velocity, time-travel characteristic curve.
5. Current measurement: the current value of the closing coil and the closing coil, the current waveform
6. Action voltage measurement: digital adjustable circuit breaker action power supply, automatic completion of low voltage circuit breaker action test, measurement of circuit breaker action voltage value.
Multi-Channel, Intelligent Detection
Equipped with 12 independent measurement channels that automatically identify and display the real-time status (open/close) of each breaker contact.
Provides clear wiring verification prompts, significantly reducing setup errors and enhancing test reliability.
Advanced Display & Intuitive Operation
Features a large, sunlight-readable grayscale touchscreen that eliminates glare for clear visibility in any environment.
User-friendly graphical menu interface (in English) with step-by-step operation guides ensures straightforward and efficient testing.
Comprehensive Testing Capabilities
Performs complete timing and travel analysis for vacuum, SF6, oil, and other high-voltage and medium-voltage circuit breakers.
Supports reclosing sequence tests (e.g., O-C, C-O, O-C-O) and minimum operating voltage determination for both opening and closing coils.
Specialized function for testing single-coil vacuum contactors.
Integrated Data Management & Analysis
Capable of storing up to 50 complete test reports directly on the device for record-keeping and comparison.
Powerful graphical analysis tools display synchronized waveforms and numerical results on one screen for in-depth diagnostics and reporting.
Built-in Safety & Protection
Incorporates automatic time-delay protection, which safely cuts off the coil supply voltage immediately after breaker operation to protect both the instrument and the equipment under test.
Flexible Operation Modes
Offers both fully automatic (motorized) and manual control testing modes to adapt to different site conditions and testing requirements.
