What is the K factor for transformers?
Table of Contents
1.0
The K-Factor, which provides a measurement of the thermal effects on transformers, is defined by the ANSI/IEEE C57. 110 standard. A K-Factor of 1.0 corresponds to a linear load (with no harmonics). The higher the K-Factor, the greater the overheating caused by the harmonics.
What is the K-4 for transformer?
A K-4 Rated transformer is rated for 35% nonlinear load. A K-7 Rated transformer is rated for 50% linear and 50% non-linear. The mix may be 50/50 at one point in time and change to 80/20 in the future. A K-13 Rated transformer is rated for 75% nonlinear loading.
What is the difference between K-4 and K-13 rated transformers?
K-Factor 13: A K-13 transformer can accommodate 200% of the harmonic loading of a K-4 rated transformer. These transformers are used for multiple receptacle circuits in health care facilities, UPS without optional input filtering, Production or assemble line equipment, Schools and classroom facilities.
What is meant by K factor?
K-factor (aeronautics), the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter. K-factor (centrifugation), relative pelleting efficiency of a given centrifuge rotor.
How do you calculate K factor?
K factor is a ratio between the distance from the neutral bend line to the inside bend radius and the material thickness. K factor uses the formula K factor = δ/T.
What is K rating?
K: Content suitable for most ages, usually those aged five and older. It should be free of coarse language, violence, and adult themes.
What are triple harmonics?
Triplen harmonics are the odd multiples of the third harmonic (h = 3, 9, 15, 21, . . .). They deserve special consideration because the system response is often considerably different for triplens than for the rest of the harmonics.
What is a k9 transformer?
Eaton’s K-Factor Transformers address the problems caused by non-linear loads and harmonics. They also compensate for stresses on a transformer’s winding insulation which prevents insulation breakdown and premature failure. The net result is longer transformer life.
What is a Type K transformer?
K-rated transformers are manufactured with heavier gauge copper and a double sized neutral conductor and have higher magnetic to resistive properties than a standard transformer which enables them to handle the heat generated by harmonic currents.
What is a k factor transformer?
K-Factor Rated Transformers Eaton’s K-Factor Transformers address the problems caused by non-linear loads and harmonics. They also compensate for stresses on a transformer’s winding insulation which prevents insulation breakdown and premature failure. The net result is longer transformer life. Photo is representative
What is a dry type K-factor transformer?
Eaton’s dry type ventilated K-factor 4, 9, 13, 20, and 30 rated transformers, designed to withstand harmful overheating effects caused by harmonics generated by non-linear loads. Options include aluminum or copper windings, indoor or outdoor applications, low temperature rise, low sound, and other custom options. United StatesSelect your location
