This occurs due to a sudden "cut-off" or suspension, or release of voltage. Sometimes this can even cause a breaker to trip, or a GFI unit to trip, due to the sudden spike.
A2.) As a magnetic field collapses it induces currents in conductors nearby.
The faster the field collapses the higher the voltage.
This applies to inductive circuits. Although an inductor (coil) may not be physically present in any particular circuit, there is always inductance present, by the very wires themselves.
All electrical circuits have reactive components - parts of the circuit that hold charge, such as inductors and capacitors. When switching these elements out, the charge they are holding cannot instantly go to zero; it's released in the form of a spike. When switching these elements into a circuit, a sag can result due to these elements attempting to absorb power. Switching in can also result in spikes due to the capacitive and reactive elements creating a "tank" circuit (the voltage will sag slightly, then spike). At their resonant frequency, the reactive and capacitive elements will cause voltages to spike signficantly (for more information, look up LC tank circuits). Similarly, switching out can result in the trapped energy between capacitive and reactive elements to pass back and forth at a resonant frequency, spiking the voltage.

What is impulse votage?
Sudden rise in Voltage is called Impulse voltage.
What are power system transients?
Power system transients are voltage or current spikes, sudden and brief increases or decreases in the supplied power. These can be harmful for some types of electronic devices, and can be seen by a brief flicker of either dimmer or brighter light from light bulbs.
A spike is a sharp and sudden rise in voltage Its duration is measured in what?
The duration of a spike is typically measured in microseconds (µs) or nanoseconds (ns), depending on the context and the specific application in electronics or signal processing. This brief timeframe highlights the transient nature of spikes, which can occur in various signals, such as electrical voltages or data transmissions.
What do you mean by Computers are susceptible to sudden surges or drops in electrical line voltage?
Computers are sensitive electronic devices violent voltage fluctuations can burn up individual components or corrupt your data.
What causes sudden voltage drop in houses incase of ac?
Often, this is due to a sudden increase in the load current due, for example, to the the starting current of a motor which has been switched on -this causes a temporary increase in the voltage drop along the line, which is often noticed when the lights in a property temporarily dim. Other causes could be due to external sources, such as a neighbour operating welding equipment.
What is a power surge protector and how does it protect electronic devices from voltage spikes?
A power surge protector is a device that safeguards electronic devices from sudden increases in voltage, known as power surges. It works by diverting excess electricity away from the devices, preventing damage caused by voltage spikes.
What do spikes do and how do they affect the performance of the device?
Spikes are sudden increases in voltage that can damage electronic devices. They can affect the performance of the device by causing malfunctions or even permanent damage. It is important to use surge protectors to prevent spikes from harming your devices.
What are 5 types of AC power fluctuations?
Voltage sags: Temporary decrease in voltage below normal levels. Voltage swells: Temporary increase in voltage above normal levels. Voltage spikes: Quick, sharp increases in voltage. Voltage surges: Sudden increases in voltage lasting longer than spikes. Harmonic distortions: Non-linear loads causing frequency deviations from the main power supply.
What is the difference between harmonic and transients?
Harmonics are multiples of the fundamental frequency found in a signal, often caused by non-linear loads in power systems. Transients, on the other hand, are brief spikes or variations in voltage or current that occur due to sudden changes in the system, such as switching operations or lightning strikes.
What does computer SPIKE mean?
A Spike is a sudden increase in voltage that lasts for a very short period and exceeds 100% of the normal voltage on a line. Spikes can be caused by lightning strikes, but can also occur when the electrical system comes back on after a blackout.
What is spike in electricity?
Spike current is mostly caused by lightning, it means a sudden rise and fall in the supply voltage, and can cause damage by breaking through insulation material that is designed for the normal supply voltage and it will most of the time leave behind a thin layer of copper that will cause a short in the circuit
Describe the differences between spikes and surges sags and brownouts and blackouts?
Spikes refer to sudden increases in voltage that last for a short duration, while surges are longer-lasting periods of elevated voltage. Sags are temporary drops in voltage, while brownouts are prolonged periods of reduced voltage. Blackouts are complete power outages where electricity is unavailable for an extended period of time.
What is a surge protector and how does it protect electronic devices from power surges?
A surge protector is a device that helps protect electronic devices from power surges by diverting excess voltage away from the devices. It acts as a barrier between the devices and the electrical outlet, preventing damage from sudden spikes in voltage.
What is impulse votage?
Sudden rise in Voltage is called Impulse voltage.
How can I prevent voltage fluctuations in my house to protect my electronic devices and appliances?
To prevent voltage fluctuations in your house and protect your electronic devices and appliances, you can use surge protectors, voltage regulators, and uninterruptible power supply (UPS) systems. These devices help stabilize and regulate the voltage supply to your devices, reducing the risk of damage from sudden spikes or drops in voltage. Additionally, ensuring proper grounding and wiring in your home can also help prevent voltage fluctuations.
What is the function of shunt reator?
it is electrical device connected with high voltage current grids in order to protect the system from sudden drop or sudden change is voltage.
What is surge voltage?
Surge voltage means sudden big voltage. Surge voltage is of two types lightening surge and switching surge or in electrical engineering, a voltage rise that endangers the insulation of electric equipment. A correct calculation of voltage surges is of great economic and practical importance in the selection of insulation and of measures for power supply system protection, particularly for voltages above 10kilo-volts(kV). There are two types of voltage surges lightning surges and system generated surges.
