Combined PVA123C bi d l ti d tCombined solution – advantages
Combined solution integrates current and
lt t f ivoltage transformers in one casing; this means significant cost reduction Lower initial investment by purchasing one unit instead of two separate transformers
Only one supporting structure is needed
Lower transportation costLower transportation cost
Lower installation cost
The only solution at a substation here space is at a premi mwhere space is at a premium

Combined PVA123T d i d tTop core design – advantages
In top core design the current module is located in transformer’s head andtransformer s head and voltage module – in its bottom tank.
This solution makes it possible to achieve high values of short circuitvalues of short circuit currents [both thermal and dynamic] as well as vast
f t d irange of rated primary currents and outputs of secondary windings.
Many customers prefer this solution.
