Page 4: Limitations To The Use Of The Hi Test® Insulator Tester
LIMITATIONS TO THE USE OF THE HI-TEST® INSULATOR TESTER Three factors limit the use of the Hi-Test Insulator Tester under energized conditions and they must be understood prior to its use: 1) On a 69 kVAC phase-to-phase nominal circuit the phase-to-ground voltage is approximately 40 kVAC. -
Page 5: Surface Contamination
SURFACE CONTAMINATION Most contaminants that collect on the surface of insulators are only conductive in the presence of moisture. There are only a few wind blown contaminants that are conductive when dry and their occurrence in any area is generally well known to the utility company. As a result, these latter types of contaminants generally will not interfere with insulator testing activities. - Page 6 Figure Two Figure Three Figure Four Figure Five Indicates 10kVDC at probes...

Page 8: Instructions For Testing Insulators
INSTRUCTIONS FOR TESTING INSULATORS Important Points of Information: 1) Insulators can be tested energized at any line voltage or de-energized using the Hi-Test Insulator Tester, subject to the limitations described in the LIMITATIONS TO THE USE OF THE HI-TEST INSULATOR TESTER section, page 4. 2) The types of physical damage usually seen during the visual examination of porcelain insulators (cracks, chips, broken skirts, flash burns, dried and flaking cement around the pins) are very poor predictors of the dielectric condition of these insulators. - Page 9 5) When to test insulators for non-visible defects: a) immediately prior to installation on the system, thereby ensuring they are not defective when installed; b) when insulators are recycled they should all be tested for non-visible defects prior to being placed in inventory; c) when troubleshooting RF/TVI and blinking light complaints as non-visible internal failures in insulators can be a source of such nuisance complaints;...
- Page 10 INTERPRETATION 1) When the probes are first placed in contact with the insulator one or two yellow lights may come on briefly and then go off - this is normal and indicates that the tester is in contact with the insulator being tested. 2) The insulator is good when the probes are in contact with the insulator and the green LED and/or the first or second yellow LED are lit.
