Example: a resistor has a stated value of 100Ω and a tolerance of 10% Calculate the tolerance range 10% of 100Ω = (10÷100) × 100Ω = 10Ω Determine the minimum and maximum resistance values: ...

Designing a high-resistance-grounding system The main challenge in designing an HRG system is determining the proper ohmic value for the neutral-grounding resistor.
