Create a Low-Maintenance Substation Transformer Oil

The ChallengeAn Old Idea Becomes A New Containment SystemConstructionBenefitsThe challenge with most oil containment systems that do not use oil-water separating systems (with tanks and pumps) is how to deal with water filling the containment basin. Obviously, if the basin is full of water when an oil leak occurs, there is no longer a contained, controlled system in the event of an oil spill. Additionally, typical oil-water separator systems are expensive and involve long-term maintenance. Other systems that have little to no maintenance may not meet newer spill requirements as they become more stringent over time. Finding a system that meets requirements, while not producing additional maintenance costs and resource demand, is a problem faced by most utilities. For years, Avista used a below-grade, impermeable-lined basin around its transformer foundations to contain oil leaks and spills. This lining for a typical distribution station power transformer was 36-by-24 feet in size, and 2.5-feet deep, around a 9-by-12-foot transformer pad, which is offset insid...Get price

Unicron - Transformers Wiki

in The BeginningFun PublicationsUnicron Trilogy Continuity FamilyTranstechLive-Action Film SeriesAnimated Continuity FamilyKnights of UnicronAsk Vector PrimeGobotsGamesBefore the dawn of time, Order and Chaos existed within an extra-dimensional entity known as The One. To explore the fledgling universe, he created the astral being known as Unicron, and then subdivided him, creating his twin, Primus. Both brothers were multiversal singularities, unique in all realities, but whereas Unicron could only exist in one universe at a time, moving between them at will, Primus existed simultaneously in all realities at once. It is suggested, in fact, that the two brothers embody the basic concepts of reality—good and evil, order and chaos—and that their continued existence is necessary for the stability of the multiverse. As Unicron and Primus went about their appointed task, venturing through the cosmos, it became apparent to Primus that Unicron was a corrupt being, and he took it upon himself to stop the threat posed to all of existence by his sibling. In combat, Primus was no match for Unicron. In cunning, however, he proved himself to be his brothers...Get price
