What is the relationship with leakage current and rated voltage of high voltage surge arrester?

Not much actually; Electrons escaping through insulating material is defined as leakage current. Insulation has both resistsance and capacitance abilities, which means current can flow through both paths. Given the nature of current it will find the quickest path. A surge arrestor dissipates (discharges) voltage spikes through a series of resistors and diodes. A surge arrestor is commanly used in applications above 100kv. Dnot confuse a surge arrestor with a surge protector, whch is basically a circuit breaker. FIRST OF ALL THERE IS NO PERFECT INSULATOR AND ELECTRONS DO NOT ESCAPE BUT THE EMF IF HI ENOUGH WILL FIND A PATH TO BLEACH ELECTRONS BECAUSE OF DIRT MOISTER WHATEVER.

What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Does the direct current flows throw capacitor?
Yes and no. A capacitor generally does not pass DC current, except for a small "leakage current", but upon the inital application of a DC voltage, the capacitor will pass current until it reaches the full potential of the applied voltage. The simple answer is no it does not. In fact we use that characteristic to "decouple" one circuit from another in amplifiers for example.
What is the relationship between current and voltage in a thermistor?
V=IRR changes as a result of the change in temperature.
What are characteristics of an ideal diode?
An ideal diode:Passes current in one direction only. (Under forward bias).Has no leakage current (passes no current under reverse bias).Has no forward voltage drop. (No voltage loss under forward bias - a real diode has Vd~=0.7)See links for more details.
The mathematical relationship between current voltage and resistance is known as?
Ohm's LawAnswerIt's not known as anything; it's simply an equation. Ohm's Law describes constant proportionality between current and voltage for certain, but not all, materials (linear or ohmic) -it has nothing to do with this equation.
What is leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
How do you test leakage on equipment?
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.
What is MCOV rating for lightning arrester?
It is Maximum Continuously Operated Voltage to select the rating of Surge arrester or lightning arrester.
Why do you have variation in leakage reactance of induction motor?
leakage reactance in induction motor depends on the reluctance of the path in which the leakage flux is establishing. with the increase in stator current the leakage flux also increases but it cannot maintain linear relationship because of saturation of the leakage flux path, even though current is increasing the flux will not increase and it'll be constant after saturation. this leakage flux links with the stator winding and induces emf which will be opposite to the supply voltage causes drop in applied voltage , the drop in the applied voltage is represented with the leakage reactance. as flux is responsible for the induction of emf , the increase in current does not increase flux after saturation and therefore emf also doesnot increase so the leakage reactance is not constant throughout the machine operation...
Why pmos is always connected to supply voltage vdd?
for reducing the leakage current.
How the voltage arrester works?
The voltage arrester works by conducting when there is enough voltage to turn it on. Often, an arrester on a primary distribution circuit has a spark gap to ground, so that lightning strikes are limited in voltage, protecting the circuit. Other types of arresters, such as MOV's, can be used in surge protectors.
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is leakage voltage?
There is no such thing.What there is is leakage current, which is the amount of undesired current flow in a branch of an actual circuit when that branch of the equivalent ideal circuit would have no current flow.Leakage current can also be used to refer to current that occurs on a path where there is no intentional circuit branch (e.g. corona discharge current to the air in a high voltage system).
Voltage of a diode at which current increases?
In a Silcon diode no current flows in the forward direction (anode to positive voltage) until approximately 0.6 - 0.7Volts is reached. Above this voltage the current rises in line with Ohms Law. In the reverse direction only micro Amps flow (leakage current) In a Germanium diode the threshold is about 0.2 volts and reverse leakage is higher.
