Non-Intrusive Switchgear Condition Assessment

About the Topic
There is a general trend in the utilities to move from systematic (time-based) maintenance to condition based maintenance and risk based maintenance taking advantage of modern diagnostic tools and the transformation of the network to the Smart Grid. The application of many of commonly used diagnostic method of switchgear is off-service, i.e. involves scheduled outages, or even worse, requires partial dismantling of switchgear. The application of continuous condition monitoring for existing high voltage circuit-breakers is expensive since involves complex retro-fitting. Moreover, the use of these diagnostic techniques on medium voltage equipment is limited. The needs of introducing new efficient diagnostic methods for switchgear in the field are increasing.
In this context, non-intrusive diagnostic methods, which are flexible and easy to use, emerge as a solution for a first-round assessment of critical parameters and detection of incipient switchgear malfunctions. CIGRE/CIRED Joint Working Group A3.32 was formed with the task to research the existing state of the art of non-intrusive methods and their field experience applied in HV and MV switchgear to assist in the evaluation of T&D switchgear conditions. In this tutorial, the overview of the existing non-intrusive switchgear diagnostic methods will be presented and definitions will be introduced.

Reservations
Please make your reservation by noon on Monday 11 Sep 2017 via the
Online Reservation Form.
*** Free food! ***
To celebrate the start of our 2017-2018 season, a family style
dinner is on us! But, you must make a reservation by the deadline,
otherwise you will have to wait to see if we have any extra food.
Also, we need your help with our 2017 membership drive! Bring a
colleague -- free food and a great PES topic!
Continuing Education
IEEE technical meetings may be acceptable as continuing education where
required for maintenance of professional engineering licensure. Refer to
the individual state's requirements for details. A receipt for one
Professional Development Hour (PDH) will be provided.
