2. Open-circuit test - Wikipedia

   en.wikipedia.org/wiki/Open-circuit_test

   Circuit diagram for open-circuit test. The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the "hole" or incomplete part of ...

3. Voltage regulation - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulation

   In the voltage regulation formula, V no load is the voltage measured at the receiving end terminals when the receiving end is an open circuit. The entire short line model is an open circuit in this condition, and no current flows in an open circuit, so I = 0 A and the voltage drop across the line given by Ohm’s law V line drop = IZ line is 0 ...

4. Open-circuit voltage - Wikipedia

   en.wikipedia.org/wiki/Open-circuit_voltage

   Open-circuit voltage (abbreviated as OCV or V OC) is the difference of electrical potential between two terminals of an electronic device when disconnected from any circuit. [1] There is no external load connected. No external electric current flows between the terminals.

5. Load regulation - Wikipedia

   en.wikipedia.org/wiki/Load_regulation

   is the voltage at maximum load. The maximum load is the one that draws the greatest current, i.e. the lowest specified load resistance (never short circuit); is the voltage at minimum load. The minimum load is the one that draws the least current, i.e. the highest specified load resistance (possibly open circuit for some types of linear ...

6. Electrical load - Wikipedia

   en.wikipedia.org/wiki/Electrical_load

   An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]

7. No-load loss - Wikipedia

   en.wikipedia.org/wiki/No-load_loss

   No-load loss (also called "fixed loss") is a portion of the loss of electricity that does not depend on the power being distributed through an electric circuit, as opposed to the load loss. [1] No-load loss typically depends on the operating voltage of a grid unit [2] and can be attributed to: dielectric loss in cables; [3] core loss in ...

8. Tap changer - Wikipedia

   en.wikipedia.org/wiki/Tap_changer

   No-load tap changer (NLTC), also known as Off-circuit tap changer (OCTC) or De-energized tap changer (DETC), is a tap changer utilized in situations in which a transformer's turn ratio does not require frequent changing and it is permissible to de-energize the transformer system. This type of transformer is frequently employed in low power- low ...

9. Circuit breaker - Wikipedia
