What is under-voltage tripping?
The Voltage of the power supply system is rated at its designed value. If this voltage goes down predetermined set value a under voltage relay can sense the change and then trips off the circuit.
What is the meaning of rated power frequency withstand voltage?
The r.m.s of sinusoidal power frequency voltage that the equipment can withstand during tests under specified conditions and for a specified time
Why does under voltage cause overheating?
Overheating is a result of too much current flowing. AC motors are constant power devices, meaning they require the same amount of power to spin under a specific load. Power is equivalent to voltage times current. If voltage to a motor sags, the motor will attempt to make up the lack of voltage with an increase in current so the power stays the same. If voltage sags too much, the motor will overheat.
What should the voltage be on the positive side of the ignition coil for a 1977 power wagon with a 318 engine?
within one volt above or under battery voltage
Safe distance to build by high power lines?
whats a safe distance to build under a power line
What is a device that increase or decreases voltage in a power line?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to Transformers to provide customers with a regulated voltage at the desired voltage.
Under the articles of confederation congress had the power to declare war but had to request troops from?
Congress had the power to raise an Army by asking the States for troops.
Why does corona effect is more in village than in city under transmission lines?
for sake of safety and protection the high voltage transmission lines are erected in less populated areas ie. villages , these lines have operating voltages about 220kv , 440kv , 132 kv( high tension lines) . while in cities the voltage is distributed at low voltages ( about 11kv(industry) , 440v residential ) because of safety issue . since corona loss highly depends on the operating voltage of lines thats why it is mostly seen in villages.
What is the Voltage drop across a good fuse?
The voltage drop across a good fuse is very nearly zero, under nominal current conditions. The voltage is not exactly zero because you do want the fuse to have some resistance in order to develop enough voltage drop and dissipated power under fault conditions to blow.
What is the significance of the area under the curve on a current v voltage graph?
This value would represent the value for Power
What is the standard distance between high tension line to conductive materials?
I am planning to build a house at a place, which is located about 200 ...from high tension wires & what is a safe distance to build a house near high tensionwires? ... Even directly under high-voltagetransmission lines, the magnetic field ...positive associations between proximity to high-voltage power lines...Another AnswerThe simple answer is that it depends on the line voltage; the higher the voltage, the greater the distance. But the CORRECT answer is that you need to liaise with the electricity company which owns the line.
What is power frequency withstand voltage test?
A test done on a transformer. The voltage at the power frequency is ramped up to verify the transformer is capable of handling the stresses due to switching and natural phenomena (lighting strikes).Withstand Voltage:The voltage which has to be applied to a test object under specified conditions in a "withstand test" is called the "withstand voltage".
