Engineering AllOther (1379) Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
4 7663Respected Sir, I am from a hilly place called Darjeeling ,I have constructed house of 9 column out of which 4 of the column is under water , i have put rcc slab on top and on top of the rcc slab i have construced two room house with bricks and light roof , now i am planning to change the light roof with rcc slab for the two room, my main concern is will the column under water will hold the load of the new rcc slab coz it already 10 to 12 yrs old , i dont know what to do , can u advice me regarding this matter, weather to leave the upper floor roof light or make it rcc slab.(If i put the slab , it will require 45bags of cement and u calculate how much of steel and sand and pebbles) thanks with regard Anand
