Substation maintenance is a key part of any plant's maintenance program. Failures in key components such as racking mechanisms, meters, relays and busses are the most common cause of unplanned outages. Transmission, distribution and switching substations generally have switching, protection and control equipment and one or more transformers.

Components of the Virtual Main Arc Flash Mitigation System • An engineering study to evaluate the optimum settings for the relays and circuit breakers in the unit substation. • A switching device with fault interruption capability on the high-voltage side of the service transformer. If the high-voltage disconnecting device does not have

1.1 PURPOSE OF SUBSTATION.A substation provides a protected area for switching power circuits and may include transforming power from one voltage to another. For the purposes of this discussion, substation refers to substations and switching stations. A substation presents an inherent safety hazard because usually only some portions of the

The high voltage cabinet is still closed and elevated. I still am convinced that you cannot make an issue for arc flash hazard in that case! Have not seen the numbers to prove it either. I have seen many substation breakers fail and in many cases it has been violent and destructive to the equipment.

Saber Power Services - Houston, TX - offers Electrical System Testing, Maintenance, Commissioning, Construction and Emergency repair from 12 Volt batteries to 765KV Substations

Introduction to Substations Annotated Instructor's Guide Module Overview This module introduces trainees to the function of substations at all levels of the power grid, with an introduction to typical substation components included. Substation safety issues are reviewed, and trainees are introduced to one-line diagrams used in the power industry.

APD were contracted by Rio Tinto to carry out detailed protection studies on the HV kiosk sub and downstream LV DBs, and assess the potential hazard to personnel due to the occurrence of an Arc Flash as part of the incorporation of the new substation into the West Angelas electrical network.

This greatly reduces the risk of fire or arc flash, protecting equipment from damage, preventing injury, and avoiding supply interruption. For HV substation applications, Kirk recommends its HD Series interlocks. The lock housing, cylinder, and inner workings are manufactured entirely of 316 stainless steel.

Procedures for the booking of outages together with standardised switching sheets were also established to enable a robust portfolio of switching experiences for initial trainees and competency refreshers. Thomson Bridge continues to deliver switching training to the South Australian Switching Community on behalf of ElectraNet.

Trapped Key Interlock for Safe Access to Switchgear in HV Substations. The Trapped Key Interlock line from KIRK interlocking products provides safe access to switchgear within HV substations. Trapped key access interlocks and key exchange units restrict physical entry and prevent dangerous operating conditions, ensuring that personnel operate equipment according to the correct sequence of ...

While I know Lee's method can be used to calculate arc-flash incident energy for voltages out of this range, it makes sense to me to not typically apply labels because who really wants to be working on high voltage (i.e. 115kV) substation equipment (think substation transformer, SF-6 breaker, or MOAB) while it's energized?
