High-voltage hipot tester TC-15KVA

AC

Product overview: This automatic control console is designed for power frequency withstand-voltage testing of electrical products, components and insulating materials. It assesses insulation integrity, locates defects and quantifies overvoltage tolerance. The console supports direct setting of transformer VT ratio (password protected), audible/visual alarms and hardware/software anti-interference.

Applications:

• Routine and type testing of transformers, motors, cables, capacitors and insulating materials
• Incoming inspection, R&D validation and production line quality control

Technical specifications:

• Rated capacity: 10–300 kVA (model dependent)
• Low-voltage side current: up to 790 A
• VLDOTM output ranges: 0–250 V and 0–430 V
• Instrument voltage range: 0–100 V
• Console voltage/current measurement accuracy: 0.5% FS ±3 digits
• System measurement accuracy: 1.5% FS ±3 digits
• Timing range: 0 to 3 h 59 m 59 s
• Supply voltage: AC 220 V ±10% or AC 380 V ±10%, 50 Hz ±1 Hz
• Touch interface: 7" 800×480 full-color PLC touchscreen; OS: Windows XP (embedded)

Key features:

• 7" high-resolution PLC touchscreen
  • Unified display of voltage, current, time, status and prompts for clear monitoring
• Password-protected digital calibration
  • Replaces mechanical potentiometers with secure digital adjustment
• Programmable transformer (VT) ratio
  • Supports multiple transformer voltages via single console with password protection
• Manual and intelligent voltage ramp control
  • Step adjustment via buttons and auto-limit detection
  • Auto-reduction of boost rate near 90% of target voltage to protect accuracy
• Active safety monitoring and alarm system
  • Real-time test-in-progress display, audible/visual alarms for anomalies
• Data handling
  • Integrated printer and USB export for traceable test records
• Anti-interference design
  • Combined hardware/software noise suppression for stable operation in EMI environments

Safety & data handling: Password-protected settings, automatic overvoltage protection and auto-zero return ensure operator safety and repeatable test results. Test data can be printed or exported to USB for archiving and traceability.
