A power supply monitoring apparatus, for which a plurality of different preset reference current values and corresponding permitted times are provided, includes: a cutoff device; current detection circuits; overcurrent detection circuits; an idle-up command circuit; and a low voltage detection circuit. When an overcurrent detection circuit detects a current value equaling or exceeding at least one of the preset reference current values, and when that condition continues for a time equaling or exceeding a permitted time corresponding to the pertinent reference current value, the circuit transmits a command to the cutoff device to interrupt the current supplied to a power feeding path. Further, when the idle-up command circuit detects an increase in a supplied current, an idle-up command is issued.

When a circuit is activated, bases of transistors Q1 and Q2 making up a first current mirror circuit 7 are grounded through switch means 10, whereby a current is forcibly made to flow into the bases of the transistors Q1 and Q2. Thus, the circuit operation can be made reliable at the activation time. A part of load current is shunted with good accuracy via a resistor R1 having a first resistance value of a predetermined magnification of a resistance value of a shunt resistor Rs, the first current mirror circuit 7, and a second current mirror circuit 8, and the output end of the shunted current is grounded via a resistor R2 having a second resistance value, so that an output voltage VOUT proportional to a load current IL can be obtained with good accuracy from the resistor R2 and the load current IL can be found with good accuracy from the output voltage VOUT.

A refrigeration cycle comprises a compressor, an indoor heat exchange, an outdoor heat exchanger, a liquid receiver; and a pressure reducer connected in series to form a closed loop. The liquid receiver and the pressure reducer connected in series are connected between the indoor heat exchanger and said outdoor heat exchanger. A non-azeotropic mixture refrigerant comprising at least two kinds of refrigerant of different boiling temperatures mixed together is charged in and circulated through the refrigeration cycle. The mixing ratio of the azeotropic mixture refrigerant circulated thorough the refrigeration cycle is controlled substantially constant.

In an electric apparatus such as an electric power cable system, a high frequency pulse is induced on a conductive member such as a metal sheath, where partial discharge occurs in an insulation. The high frequency pulse is detected by means of a bypass lead wire, a metal foil electrode, a detecting coil, and the like provided on the electric apparatus without interrupting a live operation of the electric apparatus.
