First figure after type – rated voltage in kV;
DOSI – voltage divider for power take-off, for communication, for devices of measuring means.
DEO – capacitive voltage divider for electronic transformers.

1) - Depending on the insulators performance, the differences in overall and mounting dimensions of the dividers are possible. The required dimensions are specified at ordering.

Intermediate voltage for DOSI of all voltage classes - 12,064 kV.
Intermediate voltage for DEO - 100/√3 V.
Capacitive voltage dividers are completed with capacitors SMAI(V) -110√/3 (166√/3,188√/3) and SMAOI (V)-110√3 (166√/3, 188L/3) as it is indicated in Table 2. Dividers for voltage 500 and 750 kV are equipped with electrostatic screen.



DЕО-110/√3-1100 UHL1**

 

 

Application:
to complete capacitive voltage transformers of voltage classes 110, 220, 330, 500, 750 kV, to secure high-frequency communication from 24 up to 1000 kHz in AC electrical systems of frequency 50 Hz, in telecontrol devices, devices of protection, voltage measurement, power take-off.
