Series EVT/ZW32-10 Voltage Transformers

Series EVT/ZW32--10 voltage transformers is a new type of high voltage measurement and protection transformers, mainly matched with outdoor ZW32 vacuum circuit breaker. The transformers has powerful functions, the small signal output ,don’t need secondary PT conversion, and can be directly connected to secondary equipment through A/D conversion, which meets the development of "digital, intelligent and networked" and "integrated automation system of substation".
Structural features: The voltage part of this series of transformers adopts capacitive or resistive voltage division, epoxy resin casting, and a silicone rubber sleeve

■Integrates current and voltage measurement and protection signal output, and directly outputs small voltage signals, simplifying the system structure and reducing error sources
■Don’t contain iron core (or contains small iron core), will not saturate, wide frequency response range, large measurement range, good linearity, strong anti-interference ability, in the system fault state can make the protection device reliable operation.
■When the voltage output terminal is short-circuited for the second time, don’t generate overcurrent, and have not ferromagnetic resonance, which eliminates the major fault hidden dangers in the operation of the power system and ensures the safety of personnel and equipment.
■Multiple functions, small size, light weight, low energy consumption, reduce ferromagnetic pollution
