Abstract
PURPOSE: To detect leak, and indicate leak amount in an indicator in linear relation, by making a direct current ampere metter to act by half wave of amplified sine wave of output of a zero phase current transformer, and at the same time, making a relay to act through a voltage comparator.
CONSTITUTION: Output of a zero phase current transformer 1 is input to positive input terminal of a calculator amplifier 2, also to the inverted input terminal, voltage which is stabilized by Zener diode 11 is shunted by resistors 12, 13 and are input, voltage wave shape in which only half wave of sine wave in input voltage is amplified linearly is obtained at output terminal of the amplifier 2, this wave is input to next stage voltage comparator 4, relay 27 is made to be acted, and at the same time, it is impressed to a direct current ampere meter 3 through a current limiting resistor 17. Therefore, detection of leak is carried out by the relay 27, and at the same time, linear leak amount can be indicated in the ampere meter 3 by the calculation amplifier 2 in which voltage of input and output are in a linear relation.
