फ्रेंड आज हम बात करेंगे Ampere To Wire Size, कैसे निकाले By Formula, How To Calculate Ampere To Wire Size, Wire Size Formula, In Hindi By Instant Solution

SINGLE PHASE LOAD KE LIYE

P = V*I* COSfi * Efincincey

P = Power Watt

V = Voltage

I = Current Amp

Cos fi = PF (Power Factor)


Exp - 1 kw =230*I*0.8*0.8 EFINCINCY AVRAGE 80%

1000 W= 147.2 * I

I =1000/147.2= 6.79- LIGHTING LOAD


LIGHTING VOLTAGE DROP 2%

6.79*2=13.58/100=.135 ROUND VELUE .14 AMP VOLTAGE DROP

TOTAL LOAD = 6.79+.14 = 6.93 AMP LOAD ROUND OFF 7 AMP

ALUMINIUM CABLE

1 SQMM WIRE MINIUAM CURUNT 1.5 AMP

7 AMP LOAD =1/1.5*7 = 4.66SQMM WIRE SIZE

USE CABLE SIZE 6 SQ MM

COPPER CABLE

1 SQ MM WIRE MINIUM CURUNT LOAD 2.5 AMP

7 AMP LOAD = 1/2.5*7 = 2.8SQMM WIRE SIZE

USE CABLE SIZE 4 SQ MM

3 PHASE MOTOR KE LIYE

P=ROUT3* V*I *COSFI*EFINCINCY

10 KW WATT MOTOR =1.732*440*I*0.8*0.8

10000 WATT= 487.73*I

I = 10000/487.73= 20.50 AMP LOAD

MOTOR VOLTAGE DROP 5%

20.50*5/100=1.025 ROUND VALUE 1.03% VOLTAGE DROP

TOTAL LOAD 20.5.+1.03=21.53 AMP ROUND 22 AMPS

ALUMINIUM CABLE 

1 SQ MM = 1.5 AMP LOAD MINIUM 

22 AMP =1/1.5*22 = 14.66 ARROUND CABLE SIZE 16 SQ MM

COPPER CABLE 

1 SQ MM = 2.5  AMP MINIUM LOAD

22 AMP =1/2.5*22 = 8.8 SQ MM AROUND CABLE SIZE 10 SQ MM WIRE SIZE
