Next, square the deviation for each value. 111148) requires certain health insurers to provide consumer rebates if they do not meet a set financial target known as a medical loss ratio (MLR). All details about CT  CT Ratio formula  CT type  CT primary secondary current calculation. It was not calculated from ave value of Delta Ct. we identify it just that 100/5than the ratio 20:1. The mass ratio of copper per gram of chlorine in the two compounds is 2:1. jessica bedford September 23, 2017 at 3:20 pm. Hover over the circle to get more detailed information. Current transformers, or CTs, are transformers used to step down the current level of highpower transmission systems to measure or monitor the current levels. It is necessary that the proper impedance be used to represent the primary system. Basically, the formula is telling you to add every number in column B and divide it by the sum of the numbers in column C. Using current transformer size = expected amperage through the switchboard x 1. You might think, \well, Qis just x You might think, \well, Qis just x times xtimes x, so I can use the formula for multiplication of three quantities, equation (13).
