摘要： The present invention provides a method of using a current transformer for a temperature sensing device. The method determines the temperature of the current transformer's secondary winding by injecting a DC current into the secondary winding, measuring a voltage across the secondary winding, calculating the resistance of the secondary winding from the voltage induced into the secondary winding by the injected DC current and determining the secondary winding temperature by calculations or a comparison with verified resistance/temperature combinations.

摘要： A microprocessor based time-of-use electricity meter register uses an external real time clock powered by a backup battery during a power outage to measure real time elapsed during the outage. Upon detection of a power outage, line power and real time data are transferred by the microprocessor to an external, non-volatile memory, the external real time clock is energized by the backup battery and the clock reset to accumulate elapsed real time (days, hours, minutes, seconds) during the duration of the outage. Upon resumption of line power, the elapsed real time accumulated by the clock and the content of the non-volatile memory are transferred to the microprocessor, the backup battery is disconnected from the external real time clock and the real time previously stored in the nonvolatile memory is updated by the elapsed real time so that no customer billing data are lost during the outage.

摘要： A consumption meter, for measuring a consumed quantity, e.g. for charging purposes. The meter includes a measurement circuit MC and a calculator circuit of which at least one, e.g. both, is/are housed inside a casing CS. The meter further includes a sealing system including a light sensitive component LSC, e.g. a photo diode, and a light reducing element LRE, e.g. a self-adhesive label, arranged to prevent light incidence on the light sensitive component LSC, when the light reducing element LRE is in a sealing position. Thus, with such sealing system it is possible to discriminate between a sealed and an un-sealed condition of the meter. It is possible to electronically store and/or remotely communicate any detected un-sealed events. Especially, the light sensitive component LSC is also used as optical communication interface for reading and/or software re-configuration of the meter. Hereby, the light reducing element LRE is used to seal the meter against optical re-configuration, since its presence hinders use of the optical interface. If placed under a transparent and at the same time a removable part of the casing CS, then the light sensitive component LSC can also detect opening of the casing CS. Hereby, optical sealing can eliminate the need for mechanical seals.

摘要： The invention relates to an electricity meter for measuring a phase current and a voltage which are used by a user (3) over at least one phase n of an electric power distribution network (1), comprising a metrology portion (2) with an uninsulated current sensor (Rshunt) in series on the phase n conductor for measuring the current of phase Iphn from a measurement mes Vmes of the difference in potential at the terminals of the sensor, a first voltage divider (R4, R5) receiving the phase voltage as an input and outputting a measurement Vphn upstream of a difference in potentials between a first potential given by the conductor and a second potential, and a cutoff contactor (K1) in series with the current sensor. According to the invention, the metrology portion (2) comprises a monitoring device that includes a second voltage divider (R1, R2) connected in parallel on the serial assembly formed by the sensor (Rshunt) and the cutoff contactor (K1), outputting a measurement Vphn upstream/downstream that represents the difference in potential between the phase conductor downstream from the cutoff contactor (K1) and the phase conductor upstream from the metrology portion. The various measurements can be used to detect various situations (pole integrity of the cutoff contactor, fraud by short-circuit, downstream self-generation, resetting the main circuit breaker) when the contactor is open or closed.
