Single line diagram of commercial building. So how many lamps should be connected. Block diagrams are easy to follow and show the path of electricity from start to finish. 11 single core cables size 240 mm2 each three cables per phase two for neutral mccb circuit size a two cables size 3x12070 mm2 e each lift smdb g smdb 1 smdb 2 smdb 3 supply fig6 single line diagram of a typical 1104 kv substation two cables size 3x18595 mm2 e each. An electrical one line diagram is a representation of a complicated electrical distribution system into a simplified description using a single line. Calculate operating conditions of the motors if the motors are operating at 12 kv this represents 12 kv138 kv 087 per unit voltage. Present a general description of a system and its functions.
A block diagram is used primarily to. Show the path of electricity from start to finish. Electrical one line or single line diagram. The one line diagram is similar to a block diagram except that electrical elements such as switches circuit breakers transformers and capacitors are shown by standardized schematic symbols. Connect the neutral and live wire from utility pole in the first two input slots of single phase energy meter respectively as shown in fig 1. At unity power factor.
Show the major components of a system. Single line diagrams other types of diagrams. Connect the mccb moulded case circuit breaker as a two pole main switch to the incoming phase. For example i have a fixture that says 4x36 watts fluorescent lamp. It should be mentioned that one line diagrams also known as single line diagrams are used by a number of trades including hvac and plumbing but the electrical one line diagram is the most common. Show the way in which these components connect to each other.
Hvac and plumbing riser diagrams are essentially one line diagrams but they go by a different name. A low voltage motor control circuit is attached to the automatic transfer switch through a low voltage bus. Single line diagram 1. You can tell from the single line diagram that the automatic transfer switch would connect the emergency generator into the circuit to keep equipment running if power from the bus were lost. If you arent sure that how to wire a three phase energy meter then check this simple tutorial which show how to wire a single phase kwh meter digital or analog energy meter. This area of the single line diagram tells us that it is important for the equipment connected below the automatic transfer switch to keep running even if power from the bus is lost.
It is to be noted that the elements. A one line diagram or single line diagram is a simplified notation for representing an electrical system. There are 5 circuits shown on the diagram. My problem is that i am not sure that given that single line diagram above how to calculate the total load to be connected to a certain circuit and thus the number of fixtures to be connected. As we know that the single line diagram is a simplified way for representing a 3 phase power system so in case of. First of all connect the single phase energy meter to the mains supply ie.
The completed reactance diagram is shown in figure 5. The electrical elements like transformer capacitor circuit breaker bus bars are represented by the standard.
