See also:guidance on the wiring of meter stations for common situations. How to wire meter for single part supply? Voltmeter / Voltage MeterI even have shown the wiring of the meter within the main D board. For this post I designed a diagram concerning distribution wiring, we will know as this breaker or dominant fuse box. 1 0 obj Why thickness of Insulation depends on Voltage not Current? Make note that this is the same type of service that you find on most homes.

The D101 can be installed in an electrical panel on a DIN rail or on a wall using the DIN rail strip that is supplied in the kit.The device should be connected to the power grid by trained personnel with a minimum of group III approval for electrical safety when working on installations up to 1000 V. Depending on the configuration, the device can be supplied with transformers of different types: To connect the device, follow these steps: 2 - controlled output3 - current transformer, red wire, 4 - current transformer, black wire5 -socket for plug-in current transformer, Bottom group of contacts6 - zero7 - phase. The colour of the wiring should comply with AS/NZS 3000 rather than the diagrams. Homes are typically metered with a 200 amp meter base. %PDF-1.5 % And all information provided in this blog is for general knowledge only. startxref Remember that Electrical is very Dangerous. Connect the current transformer wires to the device or insert the plug of a detachable transformer in accordance with the wiring diagram. These wires connect back to the neutral to create a return path for the current. The point of delivery of electric energy is the point where the members service entrance conductors are connected to the cooperatives conductors. HWnF}WSA!].oE@qk158jm9m!UG"s9sf8^+`6:X{w4)_/bVe4Wa]yWjCrEQ3L=/b]V On the other hand, you can see, one terminal of each PT is connected together and connected to the neutral and ground.

When it is connected to a high voltage system it steps down the voltage and by calculating the turns ratio we can measure the actual system voltage. i2iXI2@5>)f6OZC9'RYZwP6{j_mS}3::n ;53h^fm-k/e .$Im# 6[ Please note this does not cover high voltage metering. Installing a current transformer in accordance with the energy direction indicator will provide better measurement accuracy. Same as one terminal of the secondary winding of each PT is connected together. endobj The meter loop shall be located on the outside of any building or structure; and shall be moved to the outside, at the members expense, if its location moves inside of a building or structure as the result of remodeling or structural additions. The member shall at all times ensure that the members premises, facilities and equipment comply with the provisions of the National Electrical Code and the National Electrical Safety Code as well as other applicable standards imposed by law or ordinance. Here, you can see the one terminal of each CT is connected together and connected to the ground. 0000019418 00000 n 6, New York, NY 10018. 0 You should expect to see a voltage of 240v between each phase. 0000040907 00000 n trailer D*9FDiN8-L#9$dP)C:WuiW!==Si1$i1uO=|\{z>Og.57`n@r}Xb|Hfrua4jn4GPsVen-'[Yy[ql*Z}ha4%= :FWW$cK-:4-wm{EY3/.aOxMcNN]L_7r gwt|K8u(6Vs "~-Y) #RD,U} 4 0 obj Some utilities fuse their metering equipment installations others do not. Privacy Statement 0 For example for Air conditioner we use the 4 mm cable which is very good for this, however, if we use 2.5 mm then its will not good for all time.In the above diagram, I sowed electrical cable with its the size in mm in which are 6mm or 8mm, 4mm, 2.5mm, and 1.5mm electrical cables. within the diagram is shown the tactic of wiring distribution mainboard type utility pole to Energy meter and so stateless person breaker and SP MCB breaker.
