What is the cable size that are used in 11kv system?
It depends on the power rating of the circuit but a common size would be 95 sq. mm up to about twice that. 11 kV systems are usually 3-phase 3-wire. Underground cables use copper while overhead ones tend to use uninsulated aluminium or aluminium conductor steel reinforced (ACSR) cables.
What should be minimum insulation resistance value for 11 kV HT cable?
65 meg ohm if it is 11 kv
How do you wire a single voltage 3-phase motor with 12 leads?
12 Lead, Single Voltage, Wye Start - Delta Run. Wye start; L1 to 1 and 7. L2 to 2 and 8. L3 to 3 and 9. All joined together 6,12,4,10,5 and 11. Delta run; L1 to 1, 6, 7, and 12. L2 to 2, 4, 8, and 10. L3 to 3, 5, 9, and 11. To reverse the direction of the motor interchange L1 and L2 of the supply voltage.
What is Dy11y11?
Postcode for Kidderminster in the West Midlands, UK. Also a vector group (connection configuration) of a 3-phase transformer.D - Means Delta Wound Primary Y - Means Wye (Star) Wound Secondary 11 - Is the phase shift between the two windings. The 11 refers to 11 on a clock face, hence 30 degrees.
How many amps will a 3 phase 380 volt 11Kw motor draw?
In order to answer this question, you need to know (a) its efficiency, and (b) its power factor at full load. 11 kW (not 'Kw') is its output power, so you need to know its efficiency in order to determine its input power. Then, because, for a three-phase system, power is equal to 1.732 times the product of the line voltage, line current, and power factor, you also need to know its power factor.
What is the cable size for 7.5 kw 3 phase motor?
Assuming it is a 400 V three-phase motor, the phase current is 11 amps, or more if the power factor is less than 1.0 (or the supply voltage is different). If it is a 400 V motor the cable should be capable of carrying 16 amps, so a 2.5 mm-sq 4-core cable is needed.
Are all large motors three-phase?
Yes, most large motors are three phase. Usually single phase motors only go up to 10 HP. Larger than this and the wire size and contactors used to control the motors becomes extreme. For example a single phase 10 HP motor on 115 volts draws 100 amps. The same single phase motor on 230 volts draws 50 amps. The same 10 HP motor on three phase system draws the following amperage; 230 volts is a 28 amp draw, 460 volts is a 14 amp draw and 575 volts is a 11 amp draw. As you can see the higher the voltage becomes, the smaller the wire feeder size is needed and much smaller size contactor can be used to control the motor.
Fuse size for 7.5 HP 3 Phase 440 Volt Motor?
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps
How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate kWh a time component is needed for the hours.
What is the cable size that are used in 11kv system?
It depends on the power rating of the circuit but a common size would be 95 sq. mm up to about twice that. 11 kV systems are usually 3-phase 3-wire. Underground cables use copper while overhead ones tend to use uninsulated aluminium or aluminium conductor steel reinforced (ACSR) cables.
What is the maximum capacity of 11kv transformer?
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
What will be the size of cable for 75 HP 220 Volts 3 phase motor?
75 HP = 55 KW 55 = 31/2 x 0.220 x I x cos φ = 31/2 x 0.220 x 0.8 x I I = 55/(31/2 x 0.220 x 0.8) = 180,42 A 3 x 70 mm2 is the size of cable for 75 HP 220 Volts 3 phase motor
What is rg-11 cable?
It's the coax cable used for Thick Ethernet.
When was Tommy Cable born?
Tommy Cable was born on 1900-11-27.
What should be minimum distance between phase to phase for 11 KV?
127 mm for Indoor
What size motor should you buy for a 11 foot inflatable boat?
officially a 15hp engine max. But, if you take a old 2 strokes, you can put more.
Can you use RG 11 cable in your house?
Yes. RG-11 is 75 ohm cable much the same as any other cable like RG-59, RG-6 or RG-56.
