WEBINAR: The purpose of performing Doble tests is to detect the presence of contamination and/or deterioration of the breaker’s insulating system. This is true for all types of circuit breakers, including those with SF6 as an insulation medium. This presentation will explain the importance and procedure for testing SF6 type circuit breakers. Several case studies will display the effectiveness of performing the tests.Find out more »
Presented by: Don Prien, Senior Principal Client Service Engineer This webinar will describe the construction of the winding insulation systems in generators and motors, and how they affect the tests. Methods for performing power factor tests, including purpose, application and tuning of the Type C Resonating Inductor will be presented. Analysis of test results, including how to interpret changes in the power factor, capacitance and tip up related to issues in the insulation systems will be discussed in depth.

WEBINAR: This webinar will discuss the use of four composite bushing types: Solid Dielectric Core (SDC), Resin Impregnated Paper (RIP), Resin Impregnated Synthetic (RIS), and Resin Impregnated Fiberglass (RIF, RIG).Find out more »
Presented by Norbert Gilbert, Senior Principal Client Service Engineer Power factor and capacitance testing of the overall insulation of a three winding transformer is a diagnostic tool that can help identify the condition of the transformer. In this webinar, Doble will explain the three winding testing procedure on a step-by-step basis so that a deep understanding of the test will be obtained. Examples will be provided that display the results obtained. REGISTER HEREFind out more »
WEBINAR: Surge arresters provide essential protection for apparatus against damaging overvoltage transients. This webinar will cover the various types of surge arresters available, how a surge arrester operates and proper implementation in the field for apparatus protection.Find out more »
