How many amps do you need to power 1hp?
The amperage of a motor is governed by the voltage that the motor operates on. Without a voltage given, an answer can not be given.
What is a output voltage?
You can compare a power supply to a waterfall of energy. The high of the waterfall is the output voltage, and the quantity of water in the river is the current intensity. The power generate is a combination of the intensity and the voltage: P=UI (the effective power is the result of the multiplication of the voltage and the intensity). That explain why higher the voltage is, less intensity is needed to have the same power. It is the same in a waterfall, higher it is, less water you need to make a mill turning.
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.
How much full load ampere in 2 horse power compressor?
It depends on the voltage of the compressor. Two horse power (electric) is 1492 watts, but watts are volts times amps, so you need to know the voltage. Since the motor is an inductive load, you will also need to know the power factor, so as to compensate for true vs apparent power.
What is the need of reactors at capacitor bank?
In the power system, reactors and capacitors banks are used for VAR support (basically to push up or pull down the system voltage). In circuits, capacitors and reactors are used for isolation, filtering, coupling, biasing, oscillating, and the list goes on and on.
What is the necessity of ac voltage regulation?
Unless you have very crude equipment, you need regulation to prevent the destruction of equipment plugges into the system.
What is the need of regulation?
To regulate the voltage
What do you understand by regulation in a transformer?
Regulation of transformer means percentage reduction of transformer secondary voltage due to transformer loading as compared to its no load voltage.Another AnswerA transformer's voltage regulation is defined as 'the change in its secondary voltage, from no-load to full-load, at a specified power factor, expressed as a percentage of its full-load voltage, with the primary supply voltage held constant'.
Does your LCD HDTV need voltage regulation?
Yes, but that regulation is built into the unit. An LCD HDTV either plugs directly into the wall or has a "power pack" that does. In either case, voltage regulation is accomplished inside the unit's power supply section, or in that external power supply. The set is largely immune to line voltage irregularities, except, of course, a power outage or a really big "sag" in the line voltage. In either case, the power supply (either the in-set one or the external one) will do the best it can until the voltage simply gets too low for it to continue to operate, then it "trips" or goes offline to protect the TV. It's that simple. No worries here.
What is voltage regulation formula?
The formula for voltage regulation is: Voltage Regulation = (V_no-load - V_full-load) / V_full-load * 100% where V_no-load is the voltage measured at no load, and V_full-load is the voltage measured at full load. The result is expressed as a percentage.
Why voltage regulation is necessasory?
Voltage may fluctuate due to improper wiring/groundings or sometimes due to sudden load changes. So as to give constant output voltage we need voltage regulation. If we let the voltage to fluctuate then it might cause damage to the equipments
Why is voltage regulation important in alternator?
because the voltage should be constant as the full transmission grid need ame voltage for synchronization of alternatos of grid
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
Why power quality is needed?
power quality means to have harmonics free transfer of power in the system as harmonics causes fluctuations in voltage and current which are not good for the equipments at home.so in order to maintain a constant voltage profile we need a good power quality
When do you need to convert the voltage for appliances?
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
How electrical power is transmitted from power plan to the consumer?
electrical power from the power plant to consumer goes through the transmission & distribution system, first we transmit the high voltage power from the power plant to sub station in sub station we step down the voltage according to need & distribute it to the demand.
Would an hp laptop work in Australia due to their high voltage?
No - you would need to buy a suitable adaptor for Australia's power system.
