Insulated Oil Gas Chromatograph Transformer Insulation Oil Tester| XHSP1700

The XHSP1700 Insulated Oil Gas Chromatograph adopts a three-detector process with one injection, two parallel columns, and one split configuration. In detection sensitivity, chromatographic peak resolution, and quantitative accuracy, it surpasses national and industry standard requirements. Connected to a network-type dedicated chromatography workstation, it serves oil-filled electrical equipment manufacturers and utility companies — delivering the best performance, most convenient operation, and most sensitive detection for transformer dissolved gas analysis (DGA).

Dissolved gas analysis is the single most important diagnostic tool for transformer condition assessment. By identifying and quantifying dissolved fault gases — hydrogen (H2), acetylene (C2H2), ethylene (C2H4), ethane (C2H6), methane (CH4), carbon monoxide (CO), and carbon dioxide (CO2) — the XHSP1700 enables precise classification of thermal faults, partial discharge, and arcing conditions according to IEC 60599 and IEEE C57.104 interpretation standards.

• Three-Detector Simultaneous Detection: Supports FID (Flame Ionization Detector), TCD (Thermal Conductivity Detector), and up to three detectors installed simultaneously — enabling complete dissolved gas profiling in a single injection run.
• Ethernet Remote Management: 10/100M adaptive Ethernet with built-in IP stack enables long-distance data transmission via enterprise LAN and Internet. Supports up to 253 chromatographs on a single network workstation with real-time monitoring, reverse control, and centralized data management.
• 6-Channel Precision Temperature Control: Six completely independent temperature control zones from 8C above ambient to 450C with 0.1C accuracy and 16-step programmable heating — delivering the thermal stability required for reproducible DGA retention times.
• 24-Bit AD Signal Processing: Low-noise, high-resolution 24-bit analog-to-digital conversion with baseline storage and baseline subtraction functions — ensuring reliable peak integration even for trace-level gas concentrations.
• Multi-Processor Parallel Architecture: Dedicated processors for temperature control, data acquisition, and communication ensure stable operation under complex multi-detector configurations — with automatic fault diagnosis and power-failure data protection.
• Chinese/English Dual Operating System: 5.7-inch color LCD display with keyboard and computer dual-control options, supporting free language switching and detector auto-identification for simplified operator workflows.
• Modular Design: Modular structure enables easy detector replacement and future upgrades — protecting laboratory investment while accommodating evolving analytical requirements.
