A.2 Function characteristics
1) The whole scheme adopts ultra-low power consumption designing;
2) Real time measurement of three-phase on-line current (cycle wave 64 points differential sampling);
3) The current sampling accuracy is within 100A±3A, 100~2000A + 5%;
4) Temperature sampling accuracy ±1ºC;
5) It can accurately identify short circuit faults on overhead lines.;
6) It can distinguish temporary fault, transient fault, permanent fault and grounding fault;
7) Support for multiple fault diagnosis methods such as threshold, increment and percentage;
8) It supports timing reset, power on automatic reset and remote reset;
9) It supports the avoidance of various non-fault situations misjudgment, such as load fluctuation, large load switching, transformer no-load switching-in flow current, line switching-in flow current, re-switching in flow current, adjacent line fault, electrified installation and disassembly, etc.
10) The 40mS minimum fault time can be accurately identified;
11) The data transmission distance with the wireless communication terminal can reach 150 meters;
12) It supports separate and matching use with handheld PDA;
13) Support handheld PDA to match or modify parameter configuration on site;
14) When the primary current is more than 10A, the power supply is automatically switched to CT;
15) When the primary current is less than 10A, the main battery is automatically charged;
16) 4pcs 3.3V 45mA solar panels charge the main battery at the same time;
17) The double battery power supply circuit design scheme of a 3.2V 600mAh lithium iron phosphate rechargeable battery (main battery) and a 3.6V 2600mAh lithium-ion sub-battery (backup battery) are adopted;
18) The structural parts are made of high permeability, rust proof and anticorrosive materials, which can electrified installation and disassembly;
19) Six LED fault indicator lights; one fault indicator' status indicator
20) Intelligent motor control failure turnover;
