Product Description:
GDJB-PC ——The use of Secondary Injection Tester
1. Testing of all individual components in the secondary dispatch (current, voltage, time, differential, balance, negative sequence, distance, power direction, inverse time limit, frequency, synchronization, re-closing and other relays).
2. The entire group of transmissions can simulate various simple or complex transient, permanent, and transitional faults, and can superimpose transient DC components on the fundamental wave.
3. Various harmonics can be superimposed at will, and the superposition initial angle and content can be controlled online.
4. It can output different frequency alternating currents in phases, and can be used for both AC and DC.
5. Dedicated low-cycle unit, convenient to test the low-cycle low-voltage load shedding protection of the microcomputer.
6. Automatic scanning of various protection time characteristics. Scanning of power and impedance protection characteristic curves.
7. Automatic test of the differential ratio and harmonic restraint characteristics of the microcomputer main transformer protection.
8. The entire set of distance, zero sequence, and over-current protections are automatically tested.
9. The user can program the test unit to meet the special test purpose, such as the test of self-input device.
10. Various protection tests such as loss of excitation and synchronization, reverse excitation, reverse power and synchronization of the motor.
