Load regulation refers to a power supply's ability to maintain a constant output voltage despite variations in the load current, ensuring stable performance under different load conditions. Line regulation, on the other hand, measures how well a power supply can maintain its output voltage when there are changes in the input voltage. Both metrics are crucial for determining the reliability and stability of power supplies in various applications, ensuring that devices receive consistent voltage levels. High load and line regulation values indicate better performance and reliability.

How the voltage regulation in 33kv line?
It does not depend on the line. The regulation is the percentage change in voltage caused by applying the full load current, and that depends on the transformer supplying the line. A value of 5% would be typical.
What is low voltage ic 723 regulator?
ic voltage regulator is good for line or load regulation
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'.
What is percentage regulation in transfarmer?
percentage regulation is defined as [{v(no load)-v(full load)}/v(full load)]*100% it gives the variation of output dc voltage(voltage across load) with variation in load resistance
What is voltage regulation formula?
Voltage (load) regulation is to maintain a fixed voltage under different load.Voltage regulation is limiting factor to decide the size of either conductor or type of insulation.In circuit current need to be lower than this in order to keep the voltage drop within permissible values. The high voltage circuit should be carried as far as possible so that the secondary circuit have small voltage drop.% Voltage Regulation = (1.06 x P x L x PF) / (LDF x RC x DF)Where:P - Total Power in KVAL - Total Length of Line from Power Sending to Power Receiving in KM.PF - Power Factor in p.uRC - Regulation Constant (KVA-KM) per 1% drop.RC = (KV x KV x 10) / ( RCosΦ + XSinΦ)LDF - Load Distribution Factor.LDF = 2 for uniformly distributed Load on Feeder.LDF > 2 If Load is skewed toward the Power Transformer.LDF = 1 To 2 If Load is skewed toward the Tail end of Feeder.DF - Diversity Factor in p.u
Line regulation and load regulation of zener diode?
Line regulation defines as the output voltage of the zener to remain constant under input line variation. Load regulations defined as the load increases or decreases the zener will control this variation by keeping the voltage constant.

Define voltage regulation and efficiency of a short transmission line?
Voltage Regulationvoltage regulation of a line is defined as the change in voltage at the receiving end when full load at a given power factor is removed, the voltage at the sending end being kept constant. it is expressed as a fraction or a percentage of the receiving end voltage at full load. it can be written as, Per unit regulation = Vrnl - Vrfl / VrflPercent regulation = (Vrnl -Vrfl / Vrfl) * 100Efficiency of a Short Transmission LineIt is the ratio of the Power Output of the line to the Power Input of the line.
What is voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.

What is the voltage regulation of medium transmission line?
Voltage regulation is just the percentage change in voltage at the receiving/sending end of the transmission line from no load to full load. It is given by ((Vnl-Vfl)/(Vnl)) X 100%. Typically Voltage at receiving end is known to us and for the sending end Vnl is given by Vs/A. Where A is given by the ABCD parameters of the transmission line and Vs = AVr + BIr.
What is percentage regulation in transfarmer?
percentage regulation is defined as [{v(no load)-v(full load)}/v(full load)]*100% it gives the variation of output dc voltage(voltage across load) with variation in load resistance
What is the no-load voltage of a power supply that produces 24 volts at full load with a percent regulation of 10?
the voltage regulation (as a percent) = |V(no-load) -V(rated)|/|V(rated)| * 100 so if V(rated) = 24 V voltage regulation =10% then V(no-load) = 26.4 V
When voltage regulation will be zero it operate it?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
