BJ-NGJ reverse power protection relay for generator

BJ-NGJ revser relay (With unloading function) is function extensive relay, it has not only reverse power protective function, but also overload pre-alarming & unload secondary loading function, so it is more common, easy adjustment, light weight, small volume, quality is more stable.

Technical Functions
​​​​​​​
1). When power system voltage change in ±10% rated voltage, frequency changes in ±5%, it is work normal;

2). Reverse relay power: Voltage: 100V (400V as option), 50/60Hz, A: two phase , power consumption: <2VA; Rated current input: 5A, A.C two phase, power consumption: <2VA;

3). When reverse power of parallel operation reach 3-15%(continuous adjustment) rated power, time delay 3-10s (continous adjustment), reverse power application start to work;

4). When generator reach to 90-100%(adjustbale), alarm signal instant output (negative power normal open contact), after time delay 10-30s(adjustable), unload signal output;

5). Contact output capacity: Alarming output contact, b: Reverse power output contact, unloading output contact; AC380V/3A, DC28V/10A (resistance load);

6). This equipment has the function of reverse power and un-load self-inspection;

7). Environment temperature: 0-55ºC, relative humidy: 95%,  slashing, vibrating, oil mist, smoke mist occur during vessel operating;

8). Dimension: 151*106*80mm, Mounting: 140*95mm.
