E

Indoor or Outdoor Standard and Arc-Resistant Switchgear

Used to isolate and protect high-voltage circuits underground, on the surface, and in surface substations

Field Success Story

A large solution mining company has pump stations located near the water supply to provide water for processing. A filter is required to screen the water intake before it can be pumped into the mine. Even though a second filter is installed inside the pumping station, rocks, sand, and debris still get in. Typically, once a year, an employee must clean and remove the debris out of the sump with the help of a submersible pump. Having a submersible pump running while the employee is cleaning, puts them at risk for an electrical shock. To resolve the situation, our Industrial Shock-Block ® SB6100 is mounted on the inside wall of the pumping station. Now when a worker goes into the pumping station to clean the sump they are protected.

Sizing a Neutral Grounding Resistor

One of the most critical decisions when designing stable and safe electrical systems is system grounding. The key parameter that determines the neutral grounding resistor’s affect on the circuit is the let-through current. This video will focus on how to determine what level of let-through current to specify when designing a resistance-grounded system.

White Paper: Ground Fault Protection and VFDs

Death and injuries make ground (earth) faults one of the most essential hazards to mitigate. High-resistance grounding provides significant protection for equipment and personnel. Unfortunately, when variable frequency drives (VFDs) are used in resistance-grounded systems, the system may not be able to effectively detect low-level ground faults unless the equipment is adjusted accordingly. This paper explains why using VFDs in high-resistance grounding systems can be problematic and provides an in-depth discussion of how they can be overcome.

Neutral Grounding Resistor Monitoring White Paper

White Paper: Neutral Grounding Resistor Monitoring

Resistance grounding prevents many of the problems that are associated with ungrounded and solidly grounded electrical distribution and utilization systems. Resistance grounding can limit point-of-fault damages, eliminate transient overvoltages, reduce arc-flash hazards, limit voltage exposure to personnel, and provide adequate tripping levels for selective current-based ground-fault detection and coordination.
