CT Operated Thermal Over Load Relay Current setting Calculation

WebRelay class CT ratings typically take the form of a maximum voltage value dropped across the burden at 20 times rated current (i.e. 100 amps secondary current for a CT with a 5 amp nominal output rating) while maintaining an accuracy within \(\pm\)10% of the rated turns ratio. Not coincidentally, this is how CT ratios are usually selected for ... WebDec 3, 2024 · With a 1A CT secondary rating, the lead burden is reduced to 3VA, so that with the same relay burden the total becomes a maximum of 13VA. This can be provided by a CT of normal dimensions, resulting in a saving in size, weight and cost. Hence modern CTs tend to have secondary windings of 1A rating. reached home crossword https://funnyfantasylda.com
