WEBINAR: Oil testing is the best, most cost-effective means to determine the health of power transformers, load tap changers and bulk oil breakers. In this webinar, we'll discuss special programs we have developed for load tap changer and bulk oil breaker owners to optimize their maintenance programs, using data from Doble’s diagnostic package of tests.Find out more »
WEBINAR: This webinar will present key aspects of protecting your generator under abnormal conditions impacting the security and dependability of a power system. Various protective elements will be covered in this presentation including differential protection, reverse power, negative sequence, and accidental or inadvertent energization.Find out more »
WEBINAR: In this webinar, we’ll discuss an effective procurement system process which uses a detailed specification and the transformer vendor pre-approval process to identify suitable power transformer vendors to meet the client’s specification.Find out more »
WEBINAR: This webinar will address how geomagnetic disturbances can impact transformers, new NERC standards to address geomagnetic disturbance events, and transformer thermal impact assessment requirements. Assessment approaches for service aged transformers with limited original design data will also be covered.Find out more »
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 »
WEBINAR: This webinar will highlight the benefits of performing stator and rotor tests as part of an integrated in-service diagnostic testing program. Test scheduling where the widest range of loading possibilities can be provided improves sensitivity to detect issues such as winding looseness or shorted turns.Find out more »
WEBINAR: For in-service liquid filled electric apparatus, sampling of the liquid dielectric provides a method to determine the condition of the solid and liquid insulation as well as the operating condition of the apparatus without opening or de-energizing the apparatus. This webinar will provide an overview of good insulating fluid sampling practices.Find out more »
WEBINAR: 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.Find out more »
