MSD‑10kVA/100kV Dry Type AC DC Hipot Tester
MSD‑10kVA/100kV Dry Type AC DC Hipot Tester
Product Description
Product Overview
What is Power‑Frequency Withstand Voltage Test
MSD‑10kVA/100kV system consists of intelligent touch‑screen control box and GTB dry‑type epoxy vacuum‑cast test transformer. It performs AC & DC hipot test to verify insulation performance of power‑system electrical apparatus, complying with GB/T 16927‑1997, DL/T596‑1996 standards.
Core Features
‑ Dual‑mode operation: manual voltage boost & fully‑automatic test (auto‑ramp, timing, zero‑return)
‑ Touch‑screen control; historical data view, print output; configurable test time & protection thresholds
‑ GTB dry‑type transformer: epoxy vacuum casting, lighter & smaller than oil‑immersed type, good moisture‑resistance, anti‑short‑circuit impact
‑ AC‑DC dual‑purpose; supports cascade wiring for higher‑voltage output
‑ Multiple safety protection: over‑voltage, over‑current, flashover, breakdown trip‑off
‑ Portable for field commissioning, preventive maintenance & lab high‑voltage test
Technical Specifications
Intelligent Control Box
‑ Operation modes: Manual / Automatic
‑ Functions: parameter setting, timing, data logging, print, fault protection
Dry‑Type Test Transformer
‑ Impedance voltage:4.5%‑8%; output sine‑wave; surface temperature rise<55℃
‑ Rated capacity continuous running ≤2 hours; continuous operation allowed under 2/3 rated voltage & current
