Sheath Voltage Limiter Failure From Improper Bonding of Cable Sheaths
Steady-state sheath voltages are kept within limits by proper selection of cable section lengths, grounding sheaths at strategic locations and applying sheath cross bonding for field cancellation. If performed improperly, a power cable faces increased risk of damage. Read More >
Experience With Composite Line Insulators & Impact on Purchasing Policy
Swedish transmission and distribution overhead networks have historically relied on porcelain and glass cap & pin insulators, but the past decades have seen composite insulators introduced in selected applications across 50–400 kV applications with varying outcomes. Read More >
