Smart grid development is inseparable from the current sensor security

Urban consumption continued to increase , the construction of the smart grid has become an inevitable trend , however, also need to get the power of security, this time showing the current sensor indispensable role . Also in the process of current Engine Water Temperature Sensor technology , and other aspects of the design and effectiveness of continuous improvement in the industry for more than the current flow measurement has a major role Fiber-optic current sensors for example, China launched a XDGDL-1 fiber-optic current sensor system to achieve a full digital line current sensing loop control system , with good stability and linearity and high sensitivity to meet a large range of process precision measurement requirements.Meanwhile , the system developed a field- winding telescopic structure, easy toinstall, can avoid the interference of stray magnetic fields , bus eccentricity measurement error is less than plus or minus 0.1 %, to achieve a high-precision signal conversion program for the rectifier control devices provide high-precision analog and digital communication interface standard .With the construction of the smart grid , the requirements for increasingly high current Engine Cooling Temperature Sensor , current sensor in the future to sensitivity, stability , and many other improvements , to move higher sensitivity , stronger immunity , lower power , smarter design, more compact , integrated and improved temperature stability direction, the better for the smart grid construction and upgrade services.
