Multi-loops Power Anaylzer:
Intelligent Power Analyzer YD2080 is a powerful, safe, reliable measurement and control devices, can be widely used in power systems, environmental monitoring such as low-voltage distribution automation. Two models of transformer input optional: CT20(5A/10 mA, 50A/10mA)and CT18(50A/10mA). It achieves the following functions:
Measuring voltage and each circuit current;
Measuring forward/reverse active power and forward/reverse reactive power
Measuring power factor
Measuring frequency
Measuring phase-phase angle and forward/reverse phase voltage
Counting current active power energy of each circuit
With phase-sequence detection & one way DI control
With 3DI

DI & DO function
3DI input
Mark | Index content | Note |
DI1 | Power-cut | When power-on normally, DI1 is in close status, and when power-cut, and the second loops is power-on, DI1 closed, and the indicator blinking. Simultaneously, the time of power-on in the second loop on the LCD is timing. |
DI2 | SPD fault | When it errors, DI2 closed and the indicator blinking |
DI3 | Tripping for air-switching | When it tripping, DI3 closed, and the indicator blinking |
1DO output
Phase-sequence fault: When the phase sequence is normal (UA, UB, UC), the positive sequence voltage = average phase voltage, negative sequence voltage is 0, DO in a disconnected state; when the phase sequence fault (UA, UC, UB), the positive sequence voltage is 0, negative sequence voltage = average phase voltage, DO in the closed state, the indicator lights.
