www.dtbtest.com/PDFs/t-tap-assembly-failure.pdf

Description : Failure of T-Tap Assembly installed on a 69 KV – 437 Amp aboveground line
Problem : Determine whether the failure was an isolated incident or a systemic problem
Analysis : The failure occurred through a cascade that originated from inadequate clamping
Resolution & Recommendations :
The failure was an isolated instance with potential to be systemwide if the clamping force was not correctly applied and monitored.
