WebHigh-voltage spark testers generate a spark in a discontinuity when the discontinuity has a lower dielectric strength than the paint system. In both cases, the apparatus is connected to the metal substrate by means of a signal return cable, and a DC voltage is applied by means of a probe. When a discontinuity is detected, an alarm is triggered. WebApplication Range: 12V Gasoline vehicles car spark plugs; In automobile ignition system, the high-voltage ignition coil generates a high-voltage (10000 volts or more), and the spark plug diverts it form high-tension ignition coil into the cylinder engine, spark between the spark plug electrodes will the mixture.
WebNov 17, 2016 · High-Voltage Spark Test: This is used for determining the existences of discontinuities in coating films with a total thickness of greater than 0.5 mm (20 mil). If high-voltage spark testing equipment is used to determine coating discontinuities at a thickness of less than 0.5 mm (20 mil), it may damage the coatings as well as equipment. WebJun 15, 2024 · A high-voltage holiday detector can be destructive because the high voltage pulses used to detect holidays can burn or destroy some of the thinly coated areas. Holiday detector, high voltage type is also known as a spark tester because of the spark it gives off whenever a holiday or coating discontinuity is found.
