DGA Monitoring

Dissolved Gas Analysis monitoring is a major component of a comprehensive transformer monitoring system. Dynamic Ratings supports communication to all major DGA monitors. We recognize that DGA monitors have different advantages and no one product would be optimal for all customers. That’s why we’ve created this DGA Monitor Comparison Chart to help you make the best decision for your transformer monitoring system.

SubSafe Hydrogen Monitor

Dynamic Ratings’ SubSafe Hydrogen Monitor measures hydrogen collected in the headspace of nitrogen blanketed transformers, taking advantage of hydrogen’s low solubility rates and higher in gas concentrations, to provide more consistent and reliable warnings as to the potential presence of incipient faults.

PD and Bushing Monitor: DM Series

DM Series DTM monitors provide advanced partial discharge and bushing monitoring for transformers. The DM Series product is scalable allowing customers to extend the coverage of monitoring to suit applications today and tomorrow.  Our unique visual tools make PD data easy to interpret for first level analysis. DNP and Modbus communication protocols supported.

Hydrogen Analog Output Module

The Hydrogen Analog Output Module (AOM1) pairs with Dynamic Ratings Hydrogen sensor to provide a simple interface to any transformer monitor, relay or controller that accepts a 4-20mA signal. The AOM1 allows users to change oil types and select the optimal analog output range without the need for a PC or software, via DIP switches. Download brochure…
