SF6 density relay calibrator density monitor
SF6 switches are electrical appliances that have been widely used in power systems. And its reliable operation has also become one of the important guarantees for the stable power supply of the power system. The SF6 gas density monitor is the only means used to monitor the SF6 gas density change when installed on the SF6 switch. Therefore, the quality of the SF6 density relay tester is directly related to whether the switch can operate normally. Therefore, DL/T596-1996 "Preventive Test Regulations for Power Equipment" stipulates that SF6 density relay monitors should be checked regularly.

Relay protection CT disconnection detailed explanation
CT disconnection refers to the occurrence of circuit disconnection in the secondary circuit of the current transformer (CT), which will make the secondary side unable to transmit current signals normally to the relay protection device or measuring instrument. The main function of the current transformer is to reduce the large current in the high-voltage line to a safe level in a certain proportion to facilitate the measurement and protection of the equipment to work.
