Abstract
This paper shows a new concept of digital power meter based on the optical sensing technique. The digital power meter with isolate IC so called Photocoupler is designed and implemented. The system composed of power and analong interface circuits, micro-controller and LCD display circuits. The most errors in power meter happen on measurement and calculation process for load voltages and currents. The suggested method on this paper is to use no noise sensor and PIC microprocessor. The results of simple test for power meter prototype are showed a nearly similar date to commercial product.
