This is the third contactor and it only carries the star current. The current here is 58 % of the current in the delta contactor, which is 33% of the motor rating currents. As in the DOL calculation, the same types of contractors exist. From the chart of standard types, the type of...
Star-delta starting of induction motor stages visualisation using Arduino and LabVIEW This paper presents a lab module in learning of star-delta starting induction motor using Arduino and LabVIEW. Current, voltage and speed sensors using current transformer, voltage transformer and photo coupler respectiv...
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&...
preferably the Mahalanobis distance, does not include the classical constraints. In contrast, these are used a posteriori to evaluate the goodness of the model35. In applications to gravity mode pulsators, they are typically used to determine the range of initial parameters for the calculation of...
After scanning the blueprints, the probe zaps Deltan crew member Ilia, and she disappears. She’s not gone long, though. A few minutes later, she returns as IliaBot, a synthetic replacement created by the mysterious life force at the space cloud’s center in order to communicate with the...
Pole-changing windings using star/star-delta switching for 4:1 and 7:1 pole combinations have been developed. For arriving at these designs, a universal computer program has been developed, for a straightaway application for any pole combination (close-ratio or wide-ratio). The program has the...
“non-decriminalized” Australian statesonly 0.3% of marijuana arrests lead to jail time, but a quick back-of-the-envelope calculation suggests US numbers are very similar. And even in supposedly decriminalized states, it’s not hard for a cop who wants to get a pot user in jail to ...
“Other Environmental” on the map above, and even that includes concessions to recreational boaters and to whatever catastrophe is supposed to happen if we can’t keep the Sacramento Delta working properly. It’s hard to calculate exactly how much of California’s water goes to environmental ...
Distance from winner DeltaD1 is he approximate distance between the competitor and the winner on the finish line (times of competitors and race length are involved in the calculation) *2. Distance from previous competitor Delta D2 is the approximate distance between the competitor and the ...
KPI calculation involves taking a delta between counter values from two time intervals and then determines the percentage of successful processing of a particular procedure in that time interval. When a SessMgr crashes and then recovers, the GGSN, P-GW, SAEGW, and S-GW lose the counter values...
