Optical and Electronic Instrument Transformers
· Our factory is expert at researching Optical and Electronic instrument transformers and we have much special technology in this area.

· Current sensing technology-It adopts unique PCB technology design and makes hollow windings with different structures. Their advantages are good consistency, strong anti-jamming capacity and wide frequency bands. It can meet high requirements for intermediate data acquisition of intellect substations. The accuracy of measurement is 0.1 and it can be used to measure. We have won many state invention patents (Patent number are ZL200610019487.3, ZL200610125545.0 and ZL200820065347.4).

· Voltage sensing technology - It adopts innovative micro non-uniform electric field distribution capacitor structure and eliminates interference of the capacity from external environment under very low capacitance. We have won many state invention patents (Paten number are ZL200710169089.4, ZL200710169091.1).

· Insulating structure-It adopts unique top-type gas-insulated structure. The circuit doesn’t appear on high voltage side. And it doesn’t need any light to supply electricity. These advantages also increased the reliability. It won the state invention patent (patent number is ZL200710169090.7).

· Combined instrument transformer-It adopts innovative combined instrument transformer insulating structure and combines the measurement of current and voltage. It won the state invention patent (patent number is ZL200710169091.1).

· Intellect detection technology-It’s the first one on the word to combine the state measurement and electronic instrument transformer for intellect electronic instrument transformers on the basis of unique voltage sensing technology and insulating structure. It meets the requirements of intellect grid to do real time monitor for dielectric loss, temperature, pressure and other state data. And we are now declaring the state invention patent.
