Sample A to Z Highlights:
🔹 A – Alternator: A machine that converts mechanical energy into alternating electrical energy.
🔹 B – Busbar: A metallic strip or bar used to conduct electricity within a switchboard or substation.
🔹 C – Capacitance: The ability of a system to store an electric charge, measured in farads (F).
🔹 D – Diode: A semiconductor device that allows current to flow in only one direction.
🔹 E – Earthing: Connecting parts of an electrical system to the ground to prevent shock hazards.
🔹 F – Frequency: The number of cycles per second in an alternating current (AC), measured in hertz (Hz).
🔹 G – Ground Fault: An unintentional electrical path between a power source and a grounded surface.
🔹 H – Harmonics: Voltage or current waveforms at multiples of the fundamental frequency that can distort power systems.
🔹 I – Impedance: The total opposition a circuit offers to the flow of alternating current.
🔹 J – Joule: The SI unit of energy, representing the work done when one ampere passes through one ohm for one second.
🔹 K – Kilovolt (kV): A unit of electric potential equal to 1,000 volts.
🔹 L – Load: The power consumed by a device or circuit.
🔹 M – Motor: An electrical machine that converts electrical energy into mechanical motion.
🔹 N – Neutral Wire: A conductor that carries current back to the source in an AC power system.
🔹 O – Overcurrent: A situation where the current exceeds the rated capacity of equipment, causing potential damage.
🔹 P – Power Factor: A measure of how effectively electrical power is being used, expressed as a ratio of real power to apparent power.
🔹 Q – Q-Factor (Quality Factor): Describes the damping of resonator circuits; a higher Q indicates less energy loss.
🔹 R – Relay: An electrically operated switch used in protection and control systems.
🔹 S – Switchgear: Assemblies of electrical disconnect switches, fuses, and circuit breakers.
🔹 T – Transformer: A device that transfers electrical energy between two or more circuits through electromagnetic induction.
🔹 U – Uninterruptible Power Supply (UPS): Provides emergency power when the main power source fails.
🔹 V – Voltage: The electrical potential difference between two points.
🔹 W – Watt: The SI unit of power, equivalent to one joule per second.
🔹 X – Reactance: The opposition to the change in current or voltage due to capacitance or inductance.
🔹 Y – Y-Connection (Wye): A method of connecting a three-phase system with a common neutral point.
🔹 Z – Zero Sequence Current: A component of unbalanced current in a three-phase system that can indicate ground faults.
