Transformer Oil Dissolved Gas Analysis and Moisture Monitor
Model: PASL-3000
HAOMAI innovatively combined semiconductor laser technology and
photo-acoustic spectroscopy together and applied it to smart grid
field.
The Transformer Oil Dissolved Gas Analysis and Moisture Monitor
PASL-3000 developed by HAOMAI is capable to measure Hydrogen(H2),
Carbon Monoxide(CO), Carbon Dioxide(CO2), Methane(CH4),
Acetylene(C2H2), Ethane(C2H6), Ethylene(C2H4), moisture(H2O) etc. 8
types dissolved gases in transformer oil, which wins good
reputation from numerous customers by convenient operation, easy
maintenance and high measuring accuracy.
Main Features
●Advanced technology. Semiconductor laser technology and
photo-acoustic spectroscopy are innovatively used for measuring
dissolved gas in transformer oil. PASL-3000 has strong anti-cross
interference ability, fast measuring response, high measuring
accuracy, good repeatability etc. features.
●All-components dissolved gas measurement and analysis. Adopt
photo-acoustic spectroscopy to measure gas component contents of
Hydrogen(H2), Carbon Monoxide(CO), Carbon Dioxide(CO2),
Methane(CH4), Acetylene(C2H2), Ethane(C2H6), Ethylene(C2H4),
moisture(H2O) etc. 8 types gases, also can be extended to measure
component contents of Nitrogen(N2) and Oxygen(O2).
●No consumables and no maintenance. There is no need for personnel
to operate the equipment. No carrier gas or recalibration is
required during operation. The constant maintenance is not needed.
●Reliable degassing. The monitor has a built-in constant
temperature vacuum degassing device, which can degassing
efficiently and quickly, and no pollution to oil samples.
●Easy installation. Installation can be completed without power
failure to reduce the economic loss of customers.
●Remote terminal display. The monitor supports MODBUS and IEC61850
protocol, which can provide remote terminal display, including
equipment operation status, real-time measurement data, data column
analysis graph, trend graph, report and warning prompt.
●Multiple data communication, remote centralized management.
Advanced remote centralized management software can summarize and
monitor the running status and test data of multiple monitors, and
provide perfect trend analysis and diagnosis results. It supports
RS485, Ethernet, GPRS, Optical Fiber etc. communication modes.
