In-plant spark testing involves a 6000-volt source, either AC or DC. The voltage potential is applied across the clean, dry glass surface by an insulated, hand-held fault probe. Any exposed metal causes a visible spark to jump between the probe and the flaw, alerting the operator to its location.
While DC testing is preferred method, it can only be used on grounded equipment. Certain glass-lined equipment are totally encapsulated with glass so that they cannot be grounded.

What are practical uses for a voltage spike?
Vehicle spark plug ignition.
What is the function of a coil?
An ignition coil (also called a spark coil) is an induction coil in a automobile's ignition system which transforms a storage battery's 12 volts to the thousands of volts needed to spark the spark plugs.This specific form of the autotransformer, together with the contact breaker, converts low voltage from a battery into the high voltage required by spark plugs in an internal combustion.source is from http://www.madabout-kitcars.com/kitcar/kb.php?aid=269
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.
How much voltage in static?
It's been said that a quarter inch length spark can be upwards of 20,000 Volts.
What could go wrong if you change the voltage on a PC power supply?
the computer will not switch on. May be the SMPS fail leading to a huge spark.
What is the spark plug voltage?
Spark plug voltage is high tension voltage, needed to jump a spark between the plus and minus poles. Needed tension is about a minimum of 10.000 Volt between the poles.
How much voltage is there in a visible spark?
30,000V for each centimeter in length. So for a spark of 2 centimeters that implies the voltage is 60,000V
How spark plugs produce high voltage?
Spark plugs don't produce high voltage they just make sparks with high voltage. The high voltage in a car is produced by running the low voltage of a car through a coil and condenser a distributor defines exactly when the spark happens to light up the fuel in the cylinder
What voltage spark plug sparks?
40000
What is the resistance of a cars spark plug since a spark plug is an open circuit?
The resistance measured under low voltage conditions should be infinite. High voltage ... like that that produces the spark ... behaves differently.
Normal value of voltage in spark plug and distributor function?
spark plug produces spark in the range of 15000-35000 volts.
will increased voltage in coil packs and widening spark help?
will icreased voltage help fuel milage
What is the purpose of the spark gap?
so the high voltage of the battery does not fry the spark plug of anything else
What is spark plug voltage in the two wheelers?
Two spark plugs helped in igniting the fuel from two directions rather then causing the voltage to be increased sufficiently to jump a small gap.
What happens if glass falls into spark plug hole?
Um, you probably shouldn't have had glass around the open spark plug hole in the first place. this could make it hard for your spark plug to fit into place, or even send the spark to the cylinder. You will have to take apart the head and remove the glass depending on how big the shard, or piece is.
What burns your spark plug coil?
excessive voltage usually. can be caused by a voltage spike at the alternator, a computer sending too much voltage, or poor wiring
What are practical uses for a voltage spike?
Vehicle spark plug ignition.
