How do you get a 380 volt 3 phase motor to run on a 220 volt 3 phase power source?

Use a transformer.


Can you use 220 Volt 3 Phase as 208 Volt 3 Phase?

Yes by using a 3-phase transformer. The size depends on how much power has to be converted.


What is mean KVA Rating of transformer?

copper loss is directly propostional to I (AMPERE) and iron loss directly propostional to V (VOLTAGE) then total losses is equal to volt ampere hence the rating of transformer in KVA. SULTAN


What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?

A single phase 600 to 240 Volt transformer using two phases of the three phase primary.


Why transformer is rating kva?

the short answer: to distinguish as an AC transformer, as opposed to a DC transformer. The long answer: A Kva stands for Kilo-Volt-Amps. The transformers mounted on telephone poles work with hundreds of thousands of volts so rather than 750,000 V, we use the abbreviation kilo, being the metric prefix for thousand and write 750 kV. As for 'VA' some high school physics tells us Voltage*Current=Power. voltage being measured in volts (V), current in amperes or amps for short (A), and power being Watts (W). However alternating current is a very fickle beast and the voltage and current vary in a wave like fashion causing the power to reverse direction. Other factors come into play such as power sag, types of electrical loads, and wasted energy, the equation soon becomes very messy. at times the power is actually negative and is flowing away from your house! so to simplify things they use Volt-Amps to represent the maximum amount of power as an absolute value that the electricity can deliver. as opposed to the USEFUL amount of power which is lower due to resistances in the wires and other loses. Engineers have to worry about the KVA when designing a system so it can handle everything thrown at it, keeping the wires from melting and that transformer from blowing up!

Can 200 tons chiller run through step up transformer 220 to 380 volt?

I guess you have a chiller unit suitable for 380Volts and you have a source voltage of 220V. You can step up 220Volts to 380 volts with a suitable rated step up transformer.

What does 40 VA mean in a transformer?

In a transformer, 40 VA refers to the apparent power rating of the transformer. VA stands for volt-ampere, which is a unit used to measure apparent power in an electrical circuit. A transformer with a rating of 40 VA can handle a maximum apparent power of 40 volt-amperes, which is the product of the voltage and current it can handle. This rating is important for determining the capacity and suitability of the transformer for specific applications.


Will 13.8 volt output transformer work for 13.5 volt transformer?

yes


How many watts does a 22VA transformer have?

A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.


Can a 5 volt. 1500 ma. power adapter be used to run a 4.5 volt appliance?

No, get a matching transformer and check the polarity and the milliamps.


Can you replace a 5 volt power supply with a 10 volt power supply?

If the power supply has a 5 volt tap on the secondary side of the transformer, yes. If there is no tap and the secondary side of the power supply is only 10 volts then no, you can not substitute the higher voltage unit.


What is meaning of apparent power in transformer?

Apparent power is the product of voltage and current in an a.c. system, and is expressed in volt amperes. The rated apparent power of a transformer is the product of its rated secondary current and rated secondary voltage.


Will 120 volt equipment work on a 110 volt transformer?

Yes.


Will 12 volt transformer work on 3 volt device?

No, it will destroy the 3 volt device.


Can you sub a 240 volt 1.5 amp transformer in place of a 240 volt 3 amp transformer?

If the load you are connecting to the transformer uses 1.5 amps or less, yes.


Can you power a 12 volt dc indicator light from a 16 volt ac door bell transformer?

No, the 12 VDC light must have a DC supply and the transformer voltage as well as being 16 volts which is too high, the output is AC.
