Problems solved by technology

The protection of 220kV and above fiber optic channels requires frequent installation and removal of the optical cable connector from the relay protection device during the protection verification test and measurement of optical power, so it is easy to cause the wear of the optical cable interface and the increase in the attenuation of the optical interface contact surface , thereby affecting the accuracy of the relay protection device calibration, and even damage to the optical cable interface will bring hidden dangers to the safe and reliable operation of the main protection of the power line

[0004] At present, the optical fiber protection devices at home and abroad do not have a standard and perfect verification process for the verification of the protection device in the field, especially the verification of the fiber channel.
