CONCLUSIONS
16 Copyright © 2010 Streamer Inc. All rights reserved.
MULTI-CHAMBER ARRESTERS AND INSULATOR-ARRESTERS
1. Multi – Chamber Insulator-Arresters (MCIAs) can be developed for any rated voltage.
2. MCIAs are very competitive with conventional lightning protection means.
3. MCIAs have a great market.
