FIELD: electric measuring equipment, equipment used for transformation of high voltage into low voltage in particular. SUBSTANCE: aim is to increase accuracy of divider transformation factor, to expand its loading capability and to decrease effect of divider on high voltage source. Divider has: electronic current amplifier and voltage transformer, measuring winding and feed-back winding of which are wound on common core. In the case high-voltage winding is connected oppositely to fed-back winding, that is loading of electronic current amplifier, input of which is connected with low-resistance input resistor. EFFECT: increased accuracy of divider transformation factor, expanded its loading capability, decreased its effect on high voltage source. |
