Current always follow path of least resistance.Occurrence of fault means current find unintentional low resistance path to return back to source . This resistance is so low, that it draw abnormally high current from source. This may cause damage to the conductor if it is not rated to deliver that high current. Also it may cause damage to source if it is not rated to deliver that current. Also, as the current suddenly increase, voltage drop increase and power system voltage dips.

When excitation failure?
Excitation failure occurs when a generator or synchronous machine fails to maintain its magnetic field, leading to a loss of voltage and stability. This can result from issues such as a malfunctioning excitation system, loss of a power supply to the exciter, or mechanical failure. The consequences can include decreased system performance, potential damage to equipment, and disruptions in power supply. Proper monitoring and maintenance of the excitation system are crucial to prevent such failures.
What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
What is a system failure rate?
It is a measure of how prone to failure a system is... how often is does not work as intended! For instance it a system fails 5 times out of 10 it would have a failure rate of 50%
What is the difference between ATS panel and AMF Panel?
ATS (automatic transfer system panel) it will transfer load from main power to emergency without operation when the power source drop below 80% or normal voltage while AMF (automatic main failure panel) this will substitute as main electricity source and reserve the generator if the main supply fail or down.
How much will it Cost to upgrade an electricity supply from phase 1 to phase 2 for a Melbourne home?
If you are asking whether it is possible to upgrade from single phase to two phase, then you should understand that a two phase system is archaic and will not be available from your electricity supply company. If you are asking whether your company can supply two lines (out of three) it's quite unlikely -they will normally supply single phase or three phase! You can likely upgrade to three-phase if you have a reason to do so -e.g. to operate three-phase motors. As for the cost -you'll have to check that our yourself!

What type of electricity supply system has been adopted in Australia?
240 volts
What is the part of the computer system that regulates the electricity the computer receives?
the power supply
What is the function of 2003 Mercedes E320 back up battery?
This small battery is for the sbc braking system. Your car uses a electronic brake pump. The battery is their for a back up electricity supply just in case there is catistrofic failure of main battery or power supply to the sbc pump.
What is phase failure relay?
These relay sense the Negative Sequence Voltage components of system supply & offers protection against Phase Failure, Phase Sequence Reversal with Under/Over Voltage conditions which are dangerous to motor winding and cause motor burnouts.
What is loadshading?
Load shedding refers to the deliberate shutdown of electricity supply to certain areas by power providers to prevent a total blackout of the power system. This is done when the demand for electricity exceeds the available supply, helping to stabilize the grid and prevent system-wide failures.
What are the potential consequences of a failure to prosecute a criminal case?
A failure to prosecute a criminal case can lead to the perpetrator not facing consequences for their actions, potentially allowing them to commit more crimes. It can also undermine public trust in the justice system and may result in a lack of closure for the victims.
What does the auxilary battery do in 2003 Mercedes e320?
It is a back up power supply to the sbc braking system. Just in case their is a total power failure with vehicles power supply.
What are the consequences of failure to obey a court order?
Failure to obey a court order can result in serious consequences, such as fines, imprisonment, or other legal penalties. Disobeying a court order can be considered contempt of court, which is a serious offense that can lead to harsh consequences. It is important to comply with court orders to avoid legal trouble and uphold the integrity of the judicial system.
What is dynamic failure?
Dynamic failure refers to a sudden and unexpected breakdown or malfunction of a system or component due to external factors such as high stress, overload, or improper operation. This type of failure can occur without warning and can lead to serious consequences if not addressed promptly.
Why wont your Mazda 6 start?
Same as with most cars, failure in the ignition system, electrical failure, failure in fuel supply. The only time mine has failed to start in over 220k miles was a knackered battery which spontaneously died.
What are supply service conductors?
Supply service conductors are the electrical conductors that provide power from the utility company's distribution system to a building or structure. They carry electricity at a higher voltage level to supply the building's internal electrical system. These conductors are usually installed overhead on poles or underground in conduits.
