Neutral Grounding Resistors – Why we use them, HRG vs LRG and technology and monitoring ground-fault and resistor failure
Neutral grounding resistors are commonly used on medium and low voltage systems to limit ground fault current. These resistors can range from letting through mA of ground-fault current up to hundreds or thousands of amps. Selecting a properly designed resistor is critical for the overall safety and operation of the system that they are implemented on. In this seminar we will discuss why neutral grounding resistors (NGRs) are used, how to size them, system considerations while using an NGR, technology available for monitoring the resistors (ground fault and resistor failure) and why monitoring is a critical safety concern.
