What is restriking voltage?
Restriking voltage is transient voltage. During the arcing time, at current zero, the voltage that shows up across the contacts is the restriking voltage.
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.
Other name of voltage to current converter?
a FET, or Feild Effect Transistor. In a FET, the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as a voltage controlled device. For example: In a MOSFET the current from drain to source depends upon the width of the depletion layer which in turn depends upon the voltage applied on the gate.
Why is it thatFET is called a voltage operated device?
since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain...so it is known as voltage controlled device.. for example..in a mosfet..the current from drain to source depends upon the width of the depletion layer..which in turn depends upon the voltage applied on the gate.. so that is the reason
Is it true that the higher a resistance value the higher the voltage drop?
Greater value resistor will absorb more voltage than smaller value. The more voltage absorb with same value current flow, the larger body mass resistor will require. Body size depends on type of resistor (material resistor is made of).
What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
What is transient voltage?
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
What is the acceptable pi value in insulation resistance?
The PI value depends on the type of equipment being tested and the voltage level. Roughly it shall not be below the value of 2.0
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
What is breakdown voltage of diode?
The critical value of the voltage, at which the breakdown of a P-N junction diode occurs is called the breakdown voltage.The breakdown voltage depends on the width of the depletion region, which, in turn, depends on the doping level. The junction offers almost zero resistance at the breakdown point.
