Product Description

 

Feature of KDJB-S30 Handheld Relay protection Tester:

1. 1. Manual test: Manual test accepts four AC voltage and three AC current inputs, allowing manual step-by-step control of the AC amplitude, phase, frequency, and sequence component amplitude. 
2. State Sequence Test: Each state can be tested for operating time, multi-state fault simulation, and up to five states can be set. Acceleration after reclosing can also be simulated.
3. Low-Frequency Load Shedding Test: This unit performs fixed-point testing of the operating value, operating time, slip lockout value, voltage lockout value, and current lockout value for low-frequency load shedding.
4. Synchronization Test: This unit can test relevant parameters of synchronization devices.
5. Harmonic Unit: This unit can perform second harmonic inrush current lockout tests on transformer differential protection.
6. Cross-Sampling Test: This unit is primarily used to measure the sampling accuracy of AC sampling devices.
7. Telesignaling Test: This unit can rapidly open two pairs of nodes, with a freely configurable interval time and a minimum resolution of 1ms.
8. Millisecond Meter: This unit can be used to coordinate on-site operation and time rollover.
