Transformer Monitors

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 on-line transformer and bushing monitoring.

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

E Series

The engineered to order E Series product provides a highly configurable hardware platform for utilities who need custom tailored solutions. Our application engineers will work with the utility or the transformer manufacturer to develop the optimal transformer monitoring solution to meet your needs. We will manufacture, program and test the solution following our ISO 9001 certified policies and processes. Our field service team provides field verification of the final installation.

Circuit Breaker and SF6 Gas Monitoring

Dynamic Ratings offers On-Line Circuit Breaker Performance and SF6 Gas Density Monitors. These on-line circuit breaker monitors are ideally suited for implementing predictive maintenance, maintenance deferral, condition based maintenance and increase environmental protection from SF6 gas leaks. These intelligent electronic devices (IED) monitor the condition of the main contacts, mechanism and dielectric; and logs the following information during CB operation:

Trip Time (mS) (also known as Opening Time)
Arc duration (mS) (phase segregated)
Clearing Time (mS) (also known as Interrupting Time)
Cumulative I2 x T or I x T on the main contacts (phase segregated) from arcing
Restrike Occurrence (phase segregated)
Mechanism opening travel time (mS)
Mechanism closing travel time (mS)
Operation Counts
