online Dissolved Gas Analyzer (DGA)
|
The
MGA2000-6 is a new generation of Online Dissolved Gas Analyzer (DGA) equipment
giving essential insight into the condition of transformers.
Extensive field use proves that MGA2000-6 provides
reliable information and represents invaluable tool
for Asset Management. Accurate knowledge of the
condition of the transformers is essential for all
electrical networks and On-line Monitoring of critical
transformers is increasingly vital. Dissolved Gas
Analysis (DGA) and moisture measurement of the insulation
oil are recognized as the most important tests for
conditions assessment of transformers. |
 |
| The “MGA2000-6
Transformer Online Multi-gas Analyzer” is a
highly reliable, online monitoring instrument and
system. It can analyze the concentrations
and accumulation rates of dissolved gases inside transformer
oil continuously, enable real-time and online monitoring.
Automatic diagnosis of transformer faults
can be performed by the fault diagnosis expert system
of MGA2000-6. Such application is significant
to prevent downtime incidents. Our technology and
its application provide technical assurances for the
transition from traditional Periodical maintenance
to advanced Condition-based maintenance. |

Detection
Principle: Using tailor-made nanocrystalline semiconductor
detector to measure hydrogen (H2), carbon monoxide
(CO), methane(CH4), ethylene(C2H4), acetylene(C2H2),
ethane(C2H6), total combustible gases (TCG); Using
moisture detection unit to detect water content
in oil |
|
|
Reliable Gas Extraction:
Vacuum Bubbling Method (VBM). High gas extraction
rate, good repetitiveness, no contamination of oil
and low gases extraction time. |
