Partial Discharge Monitoring

From sensors to software, Dynamic Ratings helps utility and industrial customers improve transmission, distribution and substation systems reliability, leading to increased maintenance savings and reduced outages. We design, manufacture and integrate innovative sensors, monitors, and controls for data collection, analysis, and diagnostics. With the use of our asset management tools, our customers realize maximum benefit from partial discharge monitoring.

We realize that a successful condition monitoring program must be built on a solid foundation that meets your needs.

DTM Transformer Monitor

DM Series 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.

RMM Partial Discharge Monitor

Rotating Machine Monitor (RMM)

The RMM provides information as to the health of the stator winding insulation in medium and high voltage motors and generators and can be used on variable frequency drives (VFD). Communications ports include Ethernet, USB and RS-485 with a standard communication protocol using ModBus. DNP-3 is available upon request.

SCM Partial Discharge Monitoring

Switchgear and Cable Monitor (SCM)

The SCM Partial Discharge Monitoring System can have up to 60 channels, which makes it a cost effective solution for monitoring large line-ups of switchgear and cable systems. Continuous, on-line monitoring of PD activity, provides the means to detect pending insulation failures that are not present in traditional maintenance practices.
