Are intended for measurements of a tangent of di­-electric losses angle and electric capacity, voltage and frequency of an alternating current, resistance to direct current isolation. 

It is intended for the differential control of dielectric characteristics of isolation of the objects which are under working voltage. 

It is intended for expansion of measurement range of electric capacity of Bridge SA7100 

It is intended for measurement of voltage losses in secondary chains of single-phase and three-phase voltage transformers, and also for measurement of capacity of loadings of voltage transformers (ТН) and…
