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 KVA
L - Total Length of Line from Power Sending to Power Receiving in KM.
PF - Power Factor in p.u
RC - 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

When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
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'.
Why conventional diode is not used for voltage regulation?
Conventional diodes are not used for voltage regulation because they lack the ability to maintain a constant output voltage across a wide range of input voltages and load conditions. Their forward voltage drop varies with current and temperature, making them unsuitable for precise voltage regulation. Instead, voltage regulation typically requires devices like Zener diodes or voltage regulators, which are designed to provide stable output voltages regardless of fluctuations in input voltage or load.
What is low voltage ic 723 regulator?
ic voltage regulator is good for line or load regulation
Why does the power factor of a load affect the voltage regulation of a transformer?
The power factor of a load affects the voltage regulation of a transformer because it influences the reactive power flow and the impedance of the transformer. A low power factor, indicating a higher proportion of reactive power, can lead to increased voltage drops across the transformer’s impedance, resulting in poorer voltage regulation. Conversely, a high power factor reduces reactive power losses and improves voltage stability. Thus, maintaining a good power factor is essential for optimal transformer performance and voltage regulation.
Is percent voltage regulation can be negative?
yes.. voltage regulation can be negative
Which is better 3 percent voltage regulation or 5 percent voltage regulation?
Percent Regulation is the regulation expressed as a percentage is a figure of merit used to specify the performance of a voltage regulator.
What is voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.

How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
What is line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What is the need of regulation?
To regulate the voltage
