Problem Connectors on Multiple Sub-Conductors

By Carl R. Tamm If you have a line with two or more sub-conductors per phase, and during an infrared inspection, a scenario is found where one of the sub-conductors has a fitting that is hotter than the one next to it, the natural tendency is to assume…

Surge Arrester Lead Length Revisited

By Waymon P. Goch Surge arrester manufacturers always recommend that line and ground leads be as short and straight as possible in all surge arrester applications. Why? The primary reason is inductive surge impedance. The selection of the best surge…

Corona Shields
CSC-0883-230	Corona shields are generally required for applications above 138 kv. The appropriate shielding is obtained by combining the ClampStar unit number with the highest anticipated system voltage. Example: CSC-1108-230 designates shielding for corona free performance of CRU/CSF/CSR-1108 units installed on a 230 kv system. **Same shield is used for 230 and 345 KV applications
CSC-0883-345 **
CSC-1108-345 **
