Understanding Load Tap Changers - Doble Engineering ...
Aug 23, 2017 Understanding Load Tap Changers. Load tap changers (LTCs) play an important role in a substation. These mechanical devices are often overlooked, but a failed LTC will cause problems at its substation and complications through the grid as load is rerouted. LTCs are often tested and maintained by the same crews that test circuit breakers.
Load Tap Changer Retrofits, Parts, and Services
Load Tap Changers have been historically impractical to retrofit due to varying flange lengths, lead configurations, operating mechanisms, and control differences. Replacement implementation has been hard to justify since excessive downtime has been required to verify design requirements. However,

Why do we use a toroid-core transformer over an E ... - Quora
Answer (1 of 3): A toroid core is wound from a single strip of transformer steel. This steel is “grain oriented”, i.e. it is processed so that all the alloy crystals are oriented in the direction of the strip. So by winding as a toroid this orientation is preserved in the direction of the flux wh...
