Mode of Regulation: electrical drive
Operation Time: working for 60 min under 100% rated voltage and current
Insulation level:
      5kV/1min Primary winding to secondary winding and earth
      10kV/1min secondary winding to primary winding and earth
Overload capability: withstand 30min at 1.2IH, 15min at 1.4IH, 5min at 1.6IH.
Note: include - magnetism oil surface indicator, servo motor driving device, position indicator with terminal contacts and protection contacts.
The symmetrical compensation and reversed polarity voltage regulation circuit is adopted so that output voltage of the regulator keeps smooth and linearity, and regulating speed can be set and to be very stable. The interlock between voltage regulator, control table and secondary switch are available.
