PROBLEM: Voltage measured in your process tank

CAUSE: Heater insulation is wet and element is connected to an ineffective ground. Wet electrical insulation will allow some amount of voltage to pass to ground. If the ground connection is poor, the voltage will pass through the lowest resistance current path available.

SOLUTION: This is a hazardous condition. Shut off power and investigate source immediately. Make sure the ground connection is secure and that a conductive uninterrupted ground path exists to the ground source. Have a qualified electrician or testing service verify the grounding system. Remove or replace any non-copper or insulating material that exists in the path and test. Test heater insulation values as noted in section 7 and replace heater as required.
