Line-type lightning-arrester performance characteristics AIEE lightning arrester subcommittee

THIS report contains the performance data for the line type arresters rated 20 to 73 kv. The characteristics of line type arresters were submitted as a committee report in AIEE Transactions, volume 57, 1938 (November section), pages 661–2. The lightning arrester subcommittee felt that it was desirable to bring the data up to date at this time; also, that the characteristics of the arresters should be made available for discharge currents up to 20,000 amperes, as well as a curve showing the volt-time gap breakdown characteristics. The data in this report were obtained from the data submitted by the manufacturers for their respective products. The average values in the report are the average of the manufacturer's average values. The tolerance from average curve was found to be ±25% for arrester breakdown and ±20% for arrester IR discharge voltage.
