What Is A Shunt Resistor?
Very precise current measurement device
Provide a voltage proportional to the current flowing through it
Specified by current carrying capability and voltage output
Governed by Ohm’s law
V=I*R
V = voltage
I = current
R = resistance
How Are Shunt Resistors Made?
Shunt resistors are made using brass as the metal and special resistive elements soldered into place onto the brass or copper terminal blocks. This is then attached to a moleded base using screws to keep it in place.
How Are Shunt Resistors Installed?
Either busbar or panel mounted.
Best practice is to place the shunt in the ground return near the voltage source.
Limits potential dielectric withstanding voltage issues
Ensures all loads are accounted for
