Secondary Winding − The secondary winding is connected in delta manner. Therefore, on the secondary side of the transformer, the line voltage will be the same as the phase voltage whereas the line current is √3 times of the phase current....
Motor full load Line-current = Motor power in watts / (1.732*Volts*Eff*pf) Main & Star-delta contactor calculation A star-delta starter consists of three contactors – The main contactor, the Delta contactor, and the star contactor. Main contactor rating = 58%X Full Load Line Current = 7....
The delta-star connection is used in step-up transformers, where neutral at the secondary side is required. The delta-star connected transformers are mainly used as generator transformer for connecting the generators to the transmission systb. ...
But if you replace the corresponding systems of stars with delta meshes (the same is applicable in vice- versa format), it will be an easier calculation to solve as compared to the complex equations and calculations. Let’s consider both the circuits as shows in Figs.- 102 and 103. If ...
Leg 2 (Put) Delta - measures the sensitivity of the Leg 2 option's theoretical value to a change in the price of the underlying asset. Break Even Probability - the probability the last price will be at or beyond the break even point at expiration. Probability Calculation We take the under...
an A/D converting circuit 33 and optimal Y time T1 and Y-▵ time T2 are calculated through an operating means 38 based on current data and then a Y switch and a ▵ switch are controlled through a control means 37 based on the calculation results.;COPYRIGHT: (C)1993,JPO&...
and officers on the ship get ahead through murder and sabotage. Most shockingly, the ship’s bearded Spock is a man of ruthless calculation and power—but still logical enough to deduce that something is very off about his returned captain (whose barbaric counterpart is quickly thrown in the ...
First, statistical models overstated the risk of the disease by an order of magnitude. Then, even after these miscalculations became apparent, other extreme measures like lockdowns, mandatory masking, coercive vaccine mandates, and a million other indignities ensued. In the end, almost everyone go...
Kirk and the elder Spock are met by a short alien officer, Keenser, who leads them inside, where they meet the current timeline's Montgomery Scott. A transporter genius, Scott was "exiled" to Delta Vega after beaming Admiral Archer's prized beagle to an unknown location during a failed ex...
capacity and ohmic resistance. Simple calculation shows that this star-connected system may be converted into an equivalent deltaconnected one if the impedances x, y and z of the delta-connected system as shown in Figure 2 fulfill the following conditions hb I 1ac y=a+c+-b z=a+bab c Wi...
