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.

The main features of Transformer Oil Dissolved Gas Analysis and Moisture Monitor PASL-3000 are as follows:

●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.

Semiconductor Laser Technology and Photo-acoustic Spectroscopy are innovatively used for Transformer Oil Dissolved Gas Analysis and Moisture Monitor PASL-3000.
