Density relay is a device used to monitor the change of gas density, 3HAB8859-1/03A is usually used in the power system to monitor the change of SF6 gas density to ensure the normal operation of power equipment.

The main function of the density relay is to monitor the density of SF6 gas. When the gas density changes, the relay will send an alarm signal to remind the operator to deal with it accordingly. In the power system, SF6 gas is widely used in high voltage switchgear, transformer, transformer and other equipment, as insulation and arc extinguishing medium. Therefore, monitoring the density of SF6 gas is one of the important measures to ensure the safe operation of the power system.

Density relays usually consist of sensors, electronic components and display units. The 3HAB8859-1/03A sensor is used to detect the density of SF6 gas, and the electronic component is responsible for processing the detected signal and output the processing result to the display unit. The display unit displays the density value of SF6 gas in real time and sends an alarm signal.

In order to ensure the accuracy of density relays, regular calibration and maintenance are required. 3HAB8859-1/03A calibration usually includes checking and adjusting the zero point, range, linearity of the relay. Maintenance includes cleaning, replacing worn components, checking wiring connections and other measures to ensure the normal operation of the relay.

In short, the density relay is one of the important monitoring devices in the power system. Through the monitoring of SF6 gas density, the abnormal situation in the equipment can be discovered and dealt with in time to ensure the safe and stable operation of the power system.
