Absence of Voltage Testing – An Update on Accepted Approaches

Absence of voltage testing is a vital step in the process of verifying and establishing a de-energized state of any electrical system. As detailed in NFPA 70E clause 4.2.5., there is a specific and approved approach to establishing an electrical safe work condition with the following steps:

  • determine all possible source of electrical supply
  • interrupt the load current, open the disconnecting device for each possible source
  • verify where possible that all blades of the disconnecting devices are open
  • release or block any stored energy
  • apply lockout device in accordance with documented and established work procedures
  • using an adequately rated portable...

Compatibility Issues with Generator-Backed Power Systems

Line-interactive uninterruptible power supply (UPS) systems play a vital role in maintaining seamless operation during power outages. Their integration with backup generators, however, can pose challenges regarding synchronization and power quality.

While both UPS systems and generators serve as safeguards against power disruptions, their integration isn't always seamless. Understanding these compatibility concerns is crucial for ensuring reliable backup power and avoiding damage to sensitive equipment.
