Introduction
Power equipment which is insulated by SF gas should install Gas density relay to monitor the density change of the equipment. If the density of SF6 gas decreased to the threshold value the replay will operate to protect the equipment prevent insulation failure of the equipment. So the reliable operation of the relay is very important.
DRT SF6 gas density relay calibration test kit is applied to check and confirm whether the relay is operated in the correct value and feedback correct logical
sequence.
Feature
1) Measure the pressure in current temperature and calculate the pressure in 20 Celsius degree automatic. So the measured operation value of relay could be displayed in both the current temperature and 20 Celsius degree in the Portable SF6 Density Relay Calibration Test Kit
2) The test kit can be applied to test the SF6 Density relay in station. No laboratory condition is required for the operation value test because of the temperature transformation calculation.
3) Fast interface connector is very convenient and reliable.The standard configure of connector can meet most the requirement of most station application.
4) All the test procedure is controlled by the MCU during the whole test. All the measure value can be displayed in the large size LCD in one frame.
