The power sector is on the cusp of unprecedented transformation, which is being driven by technological forces outside the power sector. It's not surprising, considering the convergence of digital solutions, power plant technologies and technical advancements in automation.
The United States electric energy sector that includes utilities, independent power producers, public power authorities, renewable developers etc. has been traditionally considered a relatively safe and defensive investment due to its potential for providing a steady stream of dividend income.
Breakdowns of the electrical insulation system have been documented to cause catastrophic failure of critical equipment. Partial Discharges (PD) are measured on rotating machines in order to prevent early failures occurring in stator insulation.
