NACE SP0188 - ANSWER High and Low Voltage Holiday Testing Low-Voltage Holiday Detector - ANSWER -Ground is attached directly to substrate. -Sponge saturated with a solution of tap water/wetting agent -Proper mix ratio 1oz/USgal -Proper of speed is 1ft/sec Double Stroke -Used on Coatings up to 20mils -may be used on concrete Low Voltage Holiday Detectors Common Errors - ANSWER -Failure to Keep probe in contact with surface -Moving the electrode too fast or slow -Over or under saturating the sponge -Low battery or bad lead/ground connection Telegraphing - ANSWER Can occur when surface is saturated with water and the Detector reads a different area. High Voltage Holiday Detectors - ANSWER -Can have an Output range from 800-60,000v -In General Voltage ratio 100v/1mil -Electrode Rate of 1ft/sec with a single pass -Ground connection must be made direct to metal substrate(preferred) or indirectly for pipeline in soil. High Voltage Holiday Detector Pannel - ANSWER -When determining the Voltage used, if not shown on dial use Voltage immediately below what's needed -Remember the selection must be either High or Low and the corresponding number next to the Voltage.
