摘要： The invention relates to a voltage measuring instrument and a voltage measuring method using the same. One end of the core conductor 12 of a voltage measuring instrument 10 is connected to each of the primary side receiving terminals of a transformer, and a cable for supplying power is connected to the other end of the respective core conductor 12. An amplifier 24 having a voltmeter 22 connected thereto is connected between the outer circumferential conductors 16, 16 of the voltage measuring instrument 10,10 making a pair. When the primary voltage is applied to the core conductor 12 connected to each cable, microvoltage appears in the outer circumferential conductor 16 due to electrostatic capacity between the core conductor 12 and outer circumferential conductor 16. The microvoltage is amplified by an amplifier 24 and the voltage obtained is displayed on a voltmeter 22, whereby the primary side voltage of a single phase transformer can be measured.

摘要： The invention relates to an abnormality detecting device for a phase advancing capacitor, which consists of a needle-like signal wire 9, which is mechanically interrupted when an outer casing 2 having the phase advancing capacitor 1 incorporated in an airtight state expands by an increase of the internal pressure of the casing, a tripping means for detecting interruption of the needle-like signal wire 9 and causing the phase advancing capacitor 1 to trip from power lines, and a warning means for outputting alarm when interruption of the needle-like signal wire 9 is detected. Since the tripping means operates when the internal pressure of the casing is increased when abnormality occurs in the phase advancing capacitor, the phase advancing capacitor can be prevented from explosion and being broken, and since alarm is outputted, a maintenance personnel is able to know the abnormality and to immediately replace the phase advancing capacitor, it is possible to avoid the use of power at a bad power factor.

摘要： Disclosed is a transformer structure which is blocked by coating coils (10) of a power distribution transformer (Tr1) with an insulating molding material (12), for example, a synthetic resin such as epoxy or a synthetic rubber such as butyl rubber, to a predetermined thickness. The insulating molding material (12) contains an axially opening center bore defined along the coil (10) axis and a plurality of radially opening vents (16) communicating to the center bore (14), and the outside air is distributed through the center bore (14) and the vents (16) so as to control rise in the temperature of the transformer. The coils (10) of the power distribution transformer (Tr1) may be blocked integrally with those of a current transformer (Tr2) and of a potential transformer (PT), to be electrically connected one another based on the principle of electromagnetic induction with no direct contact with one another, by charging such insulating molding material (12) around these coils. Distribution of the outside air may be enhanced by disposing air blowers (22).

The transformer structure (12) is constructed so that a molded transformer, in which a single-phase transformer is molded by a molding material, and current and instrument transformers, which are connected to the primary sides of the single-phase transformers, are molded integrally by a molding material. This transformer structure (12) is positioned and fastened in place inside a rectangular frame (14). Two of these frames (14) are stacked in the vertical direction and connected to each other. A transformer apparatus (16) which contains two of such frames (14) are stacked and connected in the vertical direction is installed inside a cubicle (10). The molded transformers are installed inside the frames (14) so that the central axes of the windings of the transformers are placed horizontally.
