Voltage Transformer
We offer a complete electrical packaged power solution we partner with our clients from project inception to commissioning and offer the full range of services encompassing all components such as design manufacture installation testing and commissioning as.
Voltage transformer. A voltage transformer has 1500 turns of wire on its primary coil and 500 turns of wire for its secondary coil. Or there s another way using the transformation prop. This ratio of 3 1 3 to 1 simply means that there are three primary windings for every one secondary winding. What will be the turns ratio tr of the transformer.
An optical voltage transformer exploits the faraday effect rotating polarized light in optical materials. Potential transformer or voltage transformer gets used in electrical power system for stepping down the system voltage to a safe value which can be fed to low ratings meters and relays. A voltage transformer is an electrical component that can step up step down or transfer a current of electricity between circuits. 2 where is the instantaneous voltage is the number of turns in a winding dφ dt is the derivative of the magnetic flux φ through one turn of the winding over time t and subscripts p and s denotes primary and secondary.
Commercially available relays and meters used for protection and metering are designed for low voltage. The electromagnetic potential transformer is a wire wound transformer. You will need the measuring instruments having higher range which literally mean huge instruments. Designed to control the voltage of a current especially in high voltage scenarios voltage transformers tend to provide a specific level of power.
Combining the ratio of eq. Power transformers is our clients go to contractor when it comes to the design of cutting edge turnkey electrical systems. Instrument transformers how will you measure ac currents and voltages of very high magnitude.
