LSM2000 transmission line sag on - line monitoring system

LSM2000 transmission line sag on - line monitoring system

The device measures the wire temperature and the angle of the hanging point in real time, and calculates the current sag by calculating it, and also measures the conductor current. The main measurement device is composed of two parts: measurement and system software. The main measuring device is spherical structure, which is used in the wire, the internal use of line current generated by the induction power supply, digital temperature sensor, high-precision angle sensor, GSM / GPRS communication mode Layer shielding and sealing a number of new technologies to ensure that the device can be in the high voltage electric field and high temperature and other adverse weather conditions reliable work.
