What is meant by regulation in a transformer?
Definition: The voltage regulation is defined as the change in the magnitude of receiving and sending voltage of the transformer. The voltage regulation determines the ability of the transformer to provide the constant voltage for variable loads. The variation of voltage depends on the load and its power factor.
What is the transformer voltage regulation?
The voltage regulation of the transformer is the percentage change in the output voltage from no-load to full-load. And since power factor is a determining factor in the secondary voltage, power factor influences voltage regulation. This means the voltage regulation of a transformer is a dynamic, load-dependent number.
What is the regulation and efficiency of a transformer?
Transformer regulation, a, is the copper loss, Pcu, divided by the output power, P0. The efficiency of a transformer is a good way to measure the effectiveness of the design. Efficiency is defined as the ratio of the output power, P0, to the input power, P;n. The difference between, P0, and, P^, is due to losses.
How do you find the regulation of a transformer?
Voltage regulation of transformer is given by
- (V0 – V) / V0
- (V0 – V) / V.
- (V – V0) / V0
- (V – V0) / V.
What is regulation in power system?
In electrical power systems, voltage regulation is a dimensionless quantity defined at the receiving end of a transmission line as: Voltage regulation in transmission lines occurs due to the impedance of the line between its sending and receiving ends.
Why is voltage regulation needed?
The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. Voltage regulators also are used in electronic equipment in which excessive variations in voltage would be detrimental.
What is regulation up and regulation down?
In most electricity markets, offering frequency regulation to the grid operator means that the generator is willing to increase or decrease output (known as “regulation up” and “regulation down”) by some amount.
What is the need of regulation in power supply?
A regulated power supply is used to ensure that the output remains constant even if the input changes. A regulated DC power supply is also known as a linear power supply, it is an embedded circuit and consists of various blocks. The regulated power supply will accept an AC input and give a constant DC output.
What are regulators used?
The purpose of a voltage regulator is to keep the voltage in a circuit relatively close to a desired value. Voltage regulators are one of the most common electronic components, since a power supply frequently produces raw current that would otherwise damage one of the components in the circuit.
Why is voltage regulation important in transformer?
Change in load causes changes in current and hence the voltage drop in the transformer winding as well. It is necessary to maintain the supply voltage of the equipment supplied by the transformer. Because the supply voltage directly affects the performance of the equipment . Hence, the voltage regulation of the transformer is significant.

What are the applications of Transformers?
The most important uses and application of Transformer are: It can rise or lower the level of level of Voltage or Current ( when voltage increases, current decreases and vice virsa because P =V x I, and Power is same ) in an AC Circuit. It can increase or decrease the value of capacitor, an inductor or resistance in an AC circuit.
