What is restriking voltage and recovery voltage?
Restriking Voltage : it is the transient voltage that exists during the arcing time. ( natural frequency kHz ). Recovery Voltage : it is the rms voltage after final arc extinction. ( normal frequency 50 or 60 Hz). both voltages appear between circuit breaker poles.
Define recovery voltage in circuit breakers?
It is the transient voltage that appears across the contacts of the circuit breaker at or near the zero current instant during arcing period. A high frequency transient voltage appears across the contacts and is caused by the rapid distribution of energy between the magnetic & electric field associated with the station & transmission lines of the system at the zero current. This transient voltage is known as restriking voltage.
What is current chopping?
When low inductive currents, such as magnetiing current of transformer, shunt reactors are interrupted by breaker, there is rapid deionization of contact space and may cause the current to be interrupted before its neutral zero. This phenomena is called current chopping. This generally occurs during opening small inductive currents by vacuum ckt brkr or air blast circuit brkr. The transient voltage having high restriking voltage RRRV appears across the contacts, unless the arc restrikes. If it restrikes a further, chop may occur or several chops may occur before the current is finally interrupted. Circuit breaker may fail to clear the current. Circuit breaker in which dielectric strength of contact space grow at slow rat, the problem of current chopping is less severe as the gap breaks down and absorbs successive magnetic energy by restriking. Oil circuit breakers are therefore suitable to such application. This is the reason that sometimes in air blast circuit breakers resistance switching is adopted.
What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
What are voltage stabilizers?
Voltage Stabilizer is also called Automatic Voltage Stabilizer or AC Voltage Stabilizer or Voltage Regulator. Actually an automatic voltage stabilizer is designed to automatically maintain a constant voltage level, with protections of equipment against voltage surges, over voltage, under voltage, smoothing impulsive noise.
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
What is mean by thresold voltage?
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
Formula for converting US voltage to India voltage?
There is no formula to convert voltage. Voltage is universal.
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
