A measured value signal is transmitted to a microcomputer 6 to be converted into the process possible number of pulses (A/D conversion) with the microcomputer 6 and then, inputted to an arithmetic part of the microcomputer 6. The arithmetic part of the microcomputer 6 identifies degrading patterns indicating the degree of degradation of the oil by a judging algorithms contained. Moreover, the degree of degradation or the residual life of the oil is computed from a calibration curve corresponding to the respective degradation patterns identified to output. A resulting output signal is shown on a display device 7.

摘要： PROBLEM TO BE SOLVED: To provide a rate calculation system capable of corresponding to individual flexible rate setting at every user. SOLUTION: A commercial power system is interrupted in its service when the commercial power system using a commercial power source is linkage- operated with an independent power system using a gas engine generator that is provided by a user. In such a case, the commercial power system and the independent power system are separated from each other, to make the gas engine generator autonomously being operated. Thus, the rate calculation system comprises an operation means 22 for calculating a gas rate based on the operational state of an interruption countermeasure system that continues the supply of power to a load connected to the independent power system.

摘要： PROBLEM TO BE SOLVED: To speed up synchronization, and to shorten starting time by sending a command to a circuit breaker, and connecting a generator to a generator busbar synchronously at the point of time, when a frequency deviation and a phase difference satisfy a shychronizing condition, controlling the difference of the frequency of the generator from that of a generator bus bar may be a specified frequency difference. SOLUTION: In a starter for a generating apparatus which starts two generators 8a, 8b successively, connects them to a generator busbar 18, and performs parallel operation, automatic synchronizing apparatuses 99a, 99b for each generator 8a, 8b is provided with an adder and subtractor 108 and a frequency difference setter 107. Here, the outputs of a frequency detector 101 and a frequency difference setter 107 are added, and moreover the output of a frequency detector 100 is subtracted by the adder and subtractor 108, in the automatic synchronizing apparatus 99b, when a generator 8b started later is connected to a generator bus bar 18 in the course of performing charging by a generator 8a which started ahead for example. Then the frequency difference between the output of the generator 8b and that of the generator bus bar 18 is enlarged to speed up synchronization.

摘要： PROBLEM TO BE SOLVED: To settle the output voltage ripple to load ripple within the range of tolerance, by amplifying the error of the output of a potential dividing circuit based on the reference voltage, and controlling the output voltage of an AC/DC circuit based on this output. SOLUTION: The output voltage supplied to load side, that is, control protection system side through power transistors TR1 and TR2 is divided by a potential dividing circuit consisting of a resistor 6 and variable resistor VR and a resistor 7, and the divided voltage is compared with the reference voltage given by a Zener diode RD3. Here, the ripple components of the output voltage are sent to the base of the transistor TR4 being an error amplifier through a potential dividing circuit, and since the reference voltage is constant, the voltage between the base and emitter of the transistor TR4 drops, and the collector currents decrease. Accordingly, the output voltage is kept constant at all times.
