How To Test For Electrical Current In Water

The danger comes from a person standing with feet in the water so he is perfectly grounded to 0 volt.

How to test for electrical current in water.

We believe this is from the electrical current flowing into the unit during normal operation and becoming solid on top and then when backwashing the system the bottom became solid also. When we dismantled the water filtration filter the media was melted on the top surface and bottom surface from granular to solid material. Common sources of electricity are going to be powerheads heaters and lighting. Flood water has the same voltage as earth which is 0 volt.

Any leakage current flowing in the green safety ground wire would be seen as a non zero reading at position 2 and any leakage current from the load to earth would show a non zero reading at positions 2 or 3. See if electrical current is going to the water heater by touching the tip of the voltage detector to the wires leading into the thermostat. Do this test in the sump as well as the aquarium. The reading you want to see is 0.

Since the green wire is included in the test at position 3 only the ground current is registered as leakage in that case. Test the power with a non contact voltage detector to make sure it s off. Touching an electrical device that has voltage on the enclosure will lead to a current through body to. It is the best electrical earth that can be found with virtually no resistance.

Ec or electrical conductivity of water is its ability to conduct an electric current. Before you start working on the hot water heater confirm that the electric power in the room the heater is in is off.
