Abstract :
A new BSO/fibre-optic voltmeter for measurement of AC voltage from 0 to 500 V has been successfully developed for practical use in various fields. This voltmeter has been given outstanding temperature stability of within ± 0.2% from ¿10°C to 85°C by using the electro-optic effect of a 4.7 mm-thick Bi12SiO20.
