SITRAM Multisense 5
In their average lifetime of 40 years, transformers endure various forms of stresses that can result in different kinds of failures (electrical, thermal, chemical, or mechanical). Transformer failures may cause e.g., costly damages of primary and secondary equipment, outages, environmental cleanup charges and a loss of reputation. DGA (Dissolved Gas Analysis) monitoring with SITRAM Multisense 5 helps utilities and industries to prevent transformer failures.
Key Features
SITRAM Multisense 5 indicates deviations and evolving faults by analyzing the concentration of 4 dissolved gases in transformer insulating oil (mineral and ester oil), and moisture. This helps to predict
and prevent fault types such as:
• High temperature thermal faults, overheated oil by monitoring C2H4
• Partial discharge, thermal faults, power discharges, rust, galvanized parts, stainless steel, sunlight by monitoring H2
• Thermal fault involving cellulose, gradually from oil oxidation by monitoring CO
• Hot spot, low energy discharge, high energy discharge (arc) by monitoring C2H2
• Measurement technology with no consumables (e.g.
reference gas) nor regular maintenance effort
Measurement technology NDIR with no consumables (e.g.,
reference gas) or regular maintenance effort
Display and keypad enabling comprehensive configuration
and setup without additional computer
Directly mounted to transformer; no additional piping, frame or
stand require; One-man work
Only one free transformer valve required (G1½ DIN ISO 228-1
or 1½” NPT ANSI B 1.20.1)
No operational interruption of the transformer during installation and commissioning
