1. The electrical installation of a shop with supply voltage of 380V, 3-phase is comprised with the following electrical loads:Single phase load:
- 20 nos. of 36W fluorescent light fitting- 4 nos. of air-conditioner unit with full load current of 10A each- 3 nos. of 30A ring circuit using 13A socket outlets- 3 nos. of refrigerator with full load current of 15A each
Three phase load:
- 2 nos. of cooking appliances with output power ratings of 8.2kW and 6.3kW respectively.- 2 nos. of 9kW instantaneous type water heaters.
(a) Assuming that all of the above electrical loads are balanced across the 3-phase supply, determine the maximum current demand by applying suitable diversity factor as given in Table 7(1) of CoP.
(b) Draw a schematic wiring diagram to show all the final circuit arrangement according to the accepted practice of the Code of Practice for this shop.
Note: NO NEED to show the current rating of the protective devices and cable size of the final circuits in the schematic wiring diagram.
If the breakover voltage of Fig. 13-40a changes to 20 V and the holding current changes to 3 mA, what is the voltage V that turns on the diode? What is the voltage that turns it off ?
Discuss the steps required in calculating the collector-emitter voltage in a VDB circuit. Why does this circuit have a very stable Q point Discuss whether transistors being used as switching circuits should be biased in the active region.
The durations of the two appointments are assumed to be independent. Given that the total duration of the two appointments turns out to be 38 minutes altogether, how long do we expect the first appointment to be?
A triangular loop is placed in the x-z plane. Assume that a dc current, I = 2A ,flows in the loop and that B = 30az mWb/m exists in the region. Find the forces and the torque on the loop.
By combining the receiver simulation with the transmitter simulation previously developed, show that the reciever simulation works properly.
A shunt DC generator has a termianl voltage duringopen-circuit of 127V. When the machine is operating at rated load,the rated terminal voltage is 120V. Find the load current ifthe field resistance is 15 ohms and the armature resistance is 0.02ohms..
How does the staging and sequence of operation for a dualfuel heat pump system differ from a traditional heat pump
Based on the data in previous Problem 2.7 and your answers to that problem, determine the average level of work-in-process (number of parts-in-process) in the plant.
Determine the distance between the poles and find out the number of poles required for the given distance - determine the illumination of the working plane and guess the type of building considering the installation is correct.
Find the sides and angles of the triangle whose vertices are i-2j+2k,2i+j-k and 3i-j+2k.
Suppose 4 equal positive charges +Q are arranged in a square as shown in the attached diagram. An "x" marks positions A, B, and C. Draw arrows showing the direction of the electric field at each of those points. (If the field strength is zero at a..
The air feels humid. No air is coming from the registers. The air handler is in the attic. An examination of the condensing unit shows that the suction line has ice all the way back to the compressor. The compressoris still running.
