What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current output.
What is a device used to change voltage of an alternating current?
A transformer.
Explain differancnce between instrument current transformer and measuring current transformer?
Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction. Current transducer is a device used to measure AC and DC current based on the halt-effect technology.
What is a current used for?
A current transformer is an electrical device which is used to transform high current to a lower standardised current for control equipment used to messure current(amps)
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
What is the reason for using a neutral current transformer on a transformer?
A current transformer is primarily used at the neutral point of a transformer for earth fault protection. A neutral current transformer will measure any ground fault current which will essentially flow from the star point of the transformer. A fault-detection device other devices is connected to the current transformer and, if the fault current exceeds a certain trigger value, the fault-detection device will give a trip command to an earth-fault relay to disconnect the supply of electricity to the transformer.
What is the transformer and starter?
A transformer is a static device which is used to step up or step down voltage without changing frequency. A starter is a device used to start the motors.It is used to limit the starting current to a safe value.
What is Primary Current?
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.
What type of device is used to decrease or increase the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What type of device is used to increase to decrease the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
