Gas Analyzer

Gas Analyzers have a modular design that offers a long-term security in your investment.
Analyzer modules can be freely combined into tailor-made solutions and upgraded or extended with new features at any time.  Remote modules are easily attached and centrally operated.
The Gas Analyzer is made up of a Flameproof enclosed Control Unit which can also contain one analyzer.

Dissolved Gas Analysis (DGA)

Knowledge of the condition of transformers is essential for all electrical networks and on-line monitoring of critical transformers is becoming increasingly vital.  This information allows valuable assets to be maximized and expensive failures to be avoided.
Dissolved Gas Analysis (DGA) and Moisture Measurement of the Insulation Oil are recognized as the most important tests for condition assessment of transformers.


  • DGA is widely accepted as the most effective method of LTC condition based monitoring.
  • Avoid Costly Unplanned Outages.
  • Transformer Faults Detected in their infancy
  • Transformer Output Optimized Safely, maximizing asset
  • Transformer Ageing can be calculated
  • Type of fault can be classified from results.
