*This series of voltage transformers are dry insulation, indoor products, suitable for power metering, power measurement and relay protection in AC lines with rated frequency of 50 Hz / 60 Hz and rated voltage of 800 V and below.

*The highest primary voltage of standard product is 800V, and the accuracy can meet 0.5 class. Special products with higher voltage or higher precision can be customized.

*The productsvoltage transformer standards of IEC61869-3:2011 and GB20840.3-2013.

*The products are environment-friendly and lead-free, comply with RoHS directive.

Specification
Notes

*The potential transformer can be used in 1.2 times of rated voltage line for a long time. When the secondary load is the maximum capacity, the temperature rise of transformer shall not exceed 60ºC.

*When the measuring instrument or relay is connected to S1 and S2 terminals, it must be noted that the total impedance (including wiring) of the connected instrument or relay does not exceed the rated load of the potential transformer.

*It is strictly forbidden to use the secondary short circuit of the potential transformer in operation.

*The potential transformer is only used in places without direct invasion of rain and snow, no serious pollution, no explosion, no severe vibration , no corrosive metal and dust or steam damaging insulation.

Application

*Voltage acquisition of low voltage distribution system.       

*Where needs to convert large current into small current.
