Testing the Voltage with Oneself

There was more static electricity during the Autumn and Winter period, and although Electrician Wu suspected that there was an electrical leakage within the aquarium equipment, there was still a need to first rule out the possibility of static electricity. Otherwise, he would be framing an innocent person.

As an experienced electrician, he placed his grandson under the care of his wife before he fetched a discarded three-pin plug. He skillfully removed the live and neutral wire, leaving only the earth wire which he had then connected to the water—if the cause was indeed because of static electricity, what he had done would have eliminated the static electricity.

However, after testing it again with a multimeter, the voltage in the water was still over 70 volts.

After ruling out the possibility that the cause might have been from static electricity, the only possibility left was an electrical leakage from the equipment.
