High-voltage transformers
The hardware trasformers of VPT, VTO voltage are the single - phase transformers which intended for application on networks of a high voltage. 

They are intended for measurement and protection of the HV distributing devices of open execution. The hardware transformers of VTS, VTD voltage are the single - phase bipolar isolated transformers are intended for application on networks of a high voltage. They intend for measurement and protection of the HV destributing devices of the closed execution.

High - voltage current transformers
The reference current trasformers CTSO, CTO are intended for measurement and protection of the HV destributing devices of open execution on tension up to 38,5 kV.

The reference hardware current transformers CTS are intended for measurements and protection of equipment of HV distributing devices of closed execution.

The hardware current transformers passed tests according to IEC 60044-1 norm.
