  • Megger-Fault_Finding_Solutions
    . For the purposes of this document on cable fault locating, only leakage current through the insulation will be considered. For shielded cable, insulation is used to limit current leakage between the phase conductor and ground or between two conductors of differing potential. As long as the leakage current
  • Ground-fault interrupters
    Ground-fault circuit interrupters (GFCIs), also called earth leakage or residual-current circuit breakers, can sense leakage current to earth ground from live parts and interrupt the circuit automatically when leakage current exceeds a predetermined value. A core-balance protection device serves
  • Lowering the Limits for Ground-Fault Protection (.pdf)
    lower trip levels without nuisance tripping. The limit to practical low-level ground-fault protection in industrial electrical systems is a function of physical parameters. Current sensing is the best method to detect and locate ground faults; however, system capacitance, unbalanced loads
  • Line-line Fault Analysis and Protection in PV Arrays
    line-line faults. in PV arrays is introduced, followed by PV current flow explanation and. current vs. voltage (I-V) characteristics analysis. To protect PV arrays from. overcurrent damages, Article 690.9 of the National Electrical Code (NEC). requires overcurrent protection devices (OCPD) in PV
  • Is Electrical Switchgear Safe?
    electrical switchgear totally safe? Today, the infrared community talks a great deal about "arc fault" or "arc flash," but to understand what an arc
  • Electrical Safety Testing Primer
    Product Safety Tests are specified to be performed during the design, development and production stages of electrical products in order to ensure that they meet basic safety requirements. These tests aim to verify that electrical products will not jeopardize the safety of the people, domestic
  • Electrical Equipment Handbook: Troubleshooting and Maintenance
    Electrical Equipment Handbook: Troubleshooting and Maintenance. In this thorough text, you will learn about the various types of transformers, motors, variable speed drives, generators, rectifiers, inverters, and uninterrupted power systems, as well as fault detection techniques, critical
  • Filter Solutions for the Regeneration of Electrical Power
    «REGEN-filter» solution from Schaffner ensures a fault free and reliable operation of systems with energy regeneration capabilities. Today, modern frequency inverters for motor speed control are an integral part of both industrial and residential applications. In regular operation, the motor acts
  • Arc Flash: Not My Fault
    End Users Are Responsible for Keeping Workers Safe From Electrical Hazards, but More of the Onus is Now on Machine Builders
  • Ground Fault Protection (.pdf)
    The wear and tear of wiring harnesses can create a safety issue in commercial aircraft, particularly in the aging ones.However, an approved and proven technology exists that can detect and isolate the electrical faults, which can otherwise escape the harness and create hazardous situations
  • Earth Ground Fault Remote Alarming & Fault Detection for Power Grids
    CAS DataLoggers recently provided the datalogging solution for an electrical utility company which needed to send alarms from remote stations in the event that the local power grid went down, and in other special cases including operational faults and security breaches.
