ZH-605D Relay Protection Testing Instrument
Detailed Product Description
Product characteristics
1. Adopt new generation of PowerPC + FPGA + 1000Mbps Ethernet hardware framework, strong computation function, fast communication, stable and reliable.
2. Simultaneously support IEC60044-8IEC61850-9-1/2 and GOOSE communication protocol.
3. Provides 1000Mbps fiber Ethernet, 6 fiber output, 1 fiber input. Achieved closed loop testing.
4. Provide 1 IRIG-B/PPM fiber output which can receive IRIG-B or PPM time signal, with GPS time error≤-1us
5. Compatible with traditional digital signal, provide 8 analog digital input and 4 analog digital output.
6. Through external configuration files can realize the configuration, such as channel name, proportion coefficient, ASDU number and sample rate, very flexible to test each different object.
7. It can test frame losing, fault frame, wrong order of communication and protocol
8. Output breadth value can be flexibly tested, according to sequence, power, three phasor balance, short circuit calculation model to set up value output.
9. It can realize Nth harmonic and inter-harmonic overlay output, the resolution of Nth harmonic and inter-harmonic is 0.25 times.
10. It has integrated fault recording function, including waveform monitoring, fault recording and analyzing, etc. It can display all action procedure in the status of before fault, fault, tripping , re-close and, The test procedure and test result is clear at a glance, convenient for analysis and inquiry problems.
11. Search boundary can show entire motion procedure, to verify the testing procedure; rich inverse time characteristic curve, which can test I-tU-tU/f-t inverse time characteristic. For I-t, the curve can be set to be general reverse time, high reverse time and extreme reverse time characteristic curve, supporting storage/no storage thermal overload reverse time, general reverse time or user-defined table reverse time characteristic.
12. Support fault simulation and COMTRADE format data replay: support simulation data output of EMTP/ATP simulation tools, and provides corresponding data conversion function; support COMTRADE 1991or COMTRADE 1999 format data replay, which satisfy each different users testing needs.
13. It can customize perfect testing report: every testing result will be saved, output format is graph, and report content can be customized.
