INVESTIGATION OF ADVANCED MEASUREMENT INFRASTRUCTURE TO MONITOR POWER QUALITY AT COMMERCIAL BUILDING IN INDONESIA
The growth of electricity meter reading technology is growing with current telecommunications technology. It developed into Automatic Meter Reading (AMR) from conventional meter reading and continued with Advanced Measurement Infrastructure (AMI). AMI utilizes currently developing telecommunications technology. With the data mining method, state electricity companies can read electricity meters, and consumers have access to monitor the quality of their power. In this research, we investigated the use of AMI in buildings in the electronics industry in Indonesia. The result is that AMI has been proven to measure meter readings, voltage, and electric current. The quality of power that can be provided includes load and voltage unbalance and total harmonic distortion of current and voltage. This investigation shows that the I-THD value is high at 84.28%, far from the permissible threshold. Apart from that, the power factor has a low value of 0.86 under low load conditions. The power factor problem is recommended to be overcome by using capacitor banks with varying values so that the capacitor can improve the power factor at low loads. Meanwhile, to overcome high I-THD, you can install filters, both passive filters and passive filters.
