Abstract

PURPOSE: To accurately detect the position of leakage, by making high the electric resistance of an ungrouded detection assisting member and a groundable detection member, which contain the equal high-resistance wire, so that the resistance of an electroconductive liquid leaked can be neglected.
CONSTITUTION: A switch S1 is closed to cause a current to flow through the circuit. The resistance of a variable resistor Q is adjusted so that an ammeter A points zero. At that time, the resistance of the variable resistor shows the front or rear end of a groundalbe detection wire. After such adjustment is finished, the switch S1 is opened so that the position of leakage is detected by a unit 1. When the high-resistance wire S is grounded at Sr due to the leakage of sodium, a potential difference takes place between points N, M and a controlling circuit C is operated and contact S2 is closed and the unit 1 is put into operation. The variable resistor Q is then adjusted so that the ammeter A points zero. The position of the leakage of sodium can be detected in terms of the resistance of the variable resistor Q.
