FIELD: measurement technology. SUBSTANCE: method of measurement of capacitance of ship power plant relative to frame refers mainly to ship high-voltage system. It uses A. C. bridge and consists in de-energizing of system, in switching on of communicational gears, in check of lack of resistance coupling to frame, in inter shorting of three phases of main distribution board. After this A. C. bridge is placed between any convenient point of current carrying parts of system and frame and summary capacitance of system relative to frame is measured. EFFECT: enhanced precision of measurements, reduced labour input into measurement process.
