Preventing Catastrophic Failure of Vault Transformers Through Online Monitoring

Network transformers provide a high level of service reliability to the downtown areas of most major cities, however, their close proximity to critical infrastructure and highly populated areas greatly increases the risk of injury and costly disruption of commerce in the instance of a catastrophic failure! Join us to learn more about the common causes of transformer failure in the network system and how to prevent them.


1:45 pm - 2:30 pm


Condition monitoring approaches for underground transmission cables

Doble is known for asset test and condition monitoring within the utility substation fence, however, Doble has applied the same core condition monitoring solutions and expertise for the critical infrastructure that connects these substations together. Tony McGrail and Jay Ganson of Doble Engineering will present two case studies/architectures showing how utilities have used condition monitoring for underground transmission lines to protect critical infrastructure.


2:30 pm - 3:15 pm

Capacitance Calculation in Electrical Bushings

Estimation of the Transmission Line Parameters viz. Capacitance, Inductance, Resistance, and Conductance per meter length are done using simulation in our programs 2D Electric and Eddy Currents solvers ELECTRO and OERSTED.

Capacitances of Electrical bushings with multiple screens are estimated in our 3D Electric Field Solver COULOMB.
