High-voltage hipot tester UHV-316Z

multi-pointelectrical conformity

Product Introduction
The UHV‑316Z Inter‑Turn Impulse Withstand Voltage Tester is a professional instrument for detecting insulation defects between layers and turns in coil-based products such as electric motors. It uses surge waveform comparison and applies controlled high‑voltage surge pulses to identify non‑coincident waveforms and localized faults.

Key Features

• Intuitive HMI: Color LCD touch screen with guided prompts and touch‑key control for fast parameter entry.
• Self‑Diagnosis & Guided Operation: Built‑in self‑check and step‑by‑step guidance to reduce setup errors.
• Extensive Parameter Storage: Up to 72 parameter groups including pre‑input standard waveforms for repeatable testing.
• Automated Timed Measurement: Scheduled, timed tests with automatic sequence control and real‑time display of test voltage and duration.
• Real‑Time Multi‑Phase Waveform Display: Simultaneous color‑coded waveform display for all measured phases to facilitate comparison.
• Automated Analysis & Archiving: Immediate waveform analysis, phase‑to‑phase error reporting and automatic storage of up to 1,000 test records.
• Adjustable Waveform Scale: On‑screen scaling for different object sizes and sensitivities.
• Single‑Circuit Support (≥10 kV): Pre‑store standard waveforms for formed coil testing and automated comparison.
• Grounding Protection: Continuous grounding detection that prevents or aborts tests if earthing is unreliable.
• Site‑Oriented Design: Panel printer and standalone cabinet design for production‑floor use without a separate PC.
