The Lightning Arrester & Leakage Tester improves overall system reliability by testing and removing from the system those arresters that are most likely to fail within a short time. When overhead arrestersfail, they generally blow themselves clear of the system and leave the system phase or phases unprotected from lightning.When underground arrestersfail, they generally cause a system outage and damage adjacent equipment. The AT-100 is designed to provide a quick test on arresters using available high voltage. It is not as sensitive as a laboratory test and will not find the most subtle types of arrester damage. It will warn the user of a damaged arrester that could fail immediately upon energizing.
The AT-100 Lightning Arrester & Leakage Tester can be used as a general-purpose DC high potential tester for testing the leakage current of devices other than arresters such as insulators, open switch contacts, crossarms, etc. Testing with DC minimizes the much higher AC capacitive current and allows the user to test for actual DC leakage current. The same green/red scale that applies to arrestersis applicable to most other equipment. For underground elbow type arresters, the arrester is connected to a 2-way feed-thru with its ground cable grounded. The Lightning Arrester & Leakage Tester is used with two ASP-15/25 load break bushing adapters for 15kV and 25kV systems or two ASP-35U's and R-69 add-on resistor sticks for 35kV systems. The instrument is connected from a live bushing to the feed-thru with the elbow arrester. As with an overhead arrester, leakage current is measured and displayed.
