On-load tap changer (OLTC), also known as On-circuit tap changer (OCTC), is a tap changer in applications where a supply interruption during a tap change is unacceptable, the transformer is often fitted with a more expensive and complex on-load tap changing mechanism. On-load tap changers may be generally classified as either mechanical ...
The tap converter is a variation on the cycloconverter, invented in 1981 by New York City electrical engineer Melvin Sandler and significantly functionally enhanced in 1982 through 1984 by graduate students Mariusz Wrzesniewski, Bruce David Wilner, and Eddie Fung.
Distribution transformers may include an off-load tap changer, which slightly adjusts the ratio between primary and secondary voltage to bring the customer's voltage within the desired range on long or heavily loaded lines. [citation needed]
Electromechanical regulators called voltage stabilizers or tap-changers, have also been used to regulate the voltage on AC power distribution lines. These regulators operate by using a servomechanism to select the appropriate tap on an autotransformer with multiple taps, or by moving the wiper on a continuously variable auto transfomer.
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @aol.com, and that the SSL encryption is enabled for incoming and outgoing mail.
The biomarker test is a spinal tap test (also called a lumbar puncture) that uses a needle to remove cerebrospinal fluid (i.e. the fluid inside your spine) to look for these specific clumping ...
President-elect Donald Trump has floated the idea of changing the name of the Gulf of Mexico to the Gulf of America. Here's why that could cause some confusion.
A tap-changer is an electrically operated (usually) mechanical device used for changing the tapping usually on the primary of a high voltage transmission transformer in order to alter the voltage at the transformer secondary for the purpose of regulation of the voltage at the load (consumer) end of the line.
