Kelman TAPTRANS
The TAPTRANS is an 9-gas on-line transformer DGA monitoring unit designed to monitor the transformer and OLTC (On-Load Tap-Changer). The TAPTRANS can sequentially measure the main, selector and divertor tanks. The photo-acoustic detection system used by the TAPTRANS allows measurement of high and low gas concentrations found in the different tanks without cross contamination. The Taptrans measures all significant fault gases (in ppm) as outlined by international standards as well as moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect and diagnose a complete range of transformer and tap-changer faults (including overheating and over tapping).  
Benefits
  • Complete solution – monitor Main, Selector and Divertor tanks monitored by same unit
  • Transformer faults detected in their infancy, minimizing costly unplanned outages and equipment failure.
  • Tapchanger outages can be minimized by planning maintenance based on dissolved gas concentrations.
 
  • Photo Acoustic Technology – no costly consumables/calibration gases required.
  • Complete monitoring and diagnostics of transformers from results.
  • Designed for field use – global installation by almost all major utilities.
Features
  • DGA & Water – Nine gases (hydrogen, methane, ethane, ethylene, acetylene, carbon monoxide, carbon dioxide, nitrogen and oxygen) plus moisture.
  • Inputs/Outputs for additional sensors including load and oil temperature.
  • Hourly Sampling – Real-time DGA results down to once per hour.
  • Communication Options – Extensive local and remote communications options.
 
  • Alarm Settings – Sophisticated programmable alarm system.
  • Acceleration of sampling rate – automatic increase in sampling rates if gas concentrations exceed caution or alarm settings.
  • Minimal Maintenance – Reduces expense and inconvenience for user.
  • Easy Installation – Simple, straightforward procedures.
Applications
  • Transformers with an oil quenched OLTC (On-Load Tap-Changer)
  • Medium/High/Critical risk and/or consequence of failure.
 
  • Industrial - Oil & Gas, Chemical plants and heavy industry.
  • Generation, Transmission, Distribution Transformers and OLTCs.
