*¹ - Upon request, VEG-24 transformers can be secondary re-connectable to lower rated primary voltages, but in such cases, at lower ratio standard characteristic (accuracy/rated output) can be:

Accuracy class 0.2 0.5 1 3
Max. Rated burden (VA) - 30 75 120

*² - Sec. terminals Marking of VEG transformers depends upon ordered combination of secondary windings.

*³ - Standard transformers are designed for total burden (on all secondary windings) up to 200 VA

Application

- VEG transformers serve as apparatus for transforming high values of primary voltages to secondary voltages suitable for feeding the measuring and protection devices, which are proscribed by standard.
- VEG transformers can be operated in indoor conditions in medium voltage networks up to 24 kV
- It is advisable to protect the transformers from direct sunlight and an excess of dust.
