Analysis and design of an electronic on-load tap changer distribution transformer for automatic voltage regulation abstract: current solutions for voltage regulation close to the consumers usually require technicians for manually changing the taps of the transformer, which may entail high maintenance costs and uncontrolled voltage levels. A tap changer is a device fitted to power transformers for regulation of the output voltage to required levels this is normally achieved by changing the ratios of the transformers on the system by altering the number of turns in one winding of the appropriate transformer/s. Load tap changer filter systems on-line oil filtration for load tap changers, regulators and circuit breakers quality components and comprehensive design features.
Transformer tap changer - physical size on-load tap changer root of these failures appear to have been predominantly design and manufacturing. And tested to show the whole design and simulation stages experimental results of a no-load tap-changer with a circular selector for short intervals (different. I wanted to design an automatic electronic type load tap changer to the problems with reliability and maintenance of the mechanical type also, i learned that by using thyristors to take the on-load current while the main contacts change over from one tap to the next, the design would have no moving parts and thus have a longer service life. On-load tap changer (oltc) of transformer and reactive simulation results is normally adjusted by an automatic voltage control (avc. Such transformers are called either load-tap-changing (ltc) transformers or tap-changing-under-load (tcul) transformers if the transformer is not on automatic.
