Industrial measurements often must take place via specialized transducers sized specifically for the current and voltage swings involved. Will Delsman | NK Technologies Older ammeters worked great when the current flowed at a steady 50 or 60 Hz. Consider the antique GE model 8AK1A1AF. I have one that remains accurate after decades of use and […]
The basics of specifying ground-fault interruption equipment
Not all ground-fault interrupters are designed to protect living beings. Specialized industrial versions are optimized for maintaining the health of machinery and processes. Will Delsman NK Technologies Ground faults arise when current flows from an energized conductor to ground inadvertently. The return path of the fault current is through living beings or equipment touching the […]
