MULTI-CONTROL DEVICE power quality MAINS

摘要

The proposed model is a useful instrument monitoring power quality (PQ) is designed for measuring, calculating, storing and possible transmission in the on-line mode the current data, including those defined by GOST 13109-97, low-voltage and high-voltage single and three phase networks. The device can be used at an energy survey companies for monitoring systems and in other cases involving the power quality analysis. The device is based on an industrial PC with a Pentium class processor 111 or higher. This PC board further has a multi-channel ADC and converting the input voltage and current signals to the ADC level. On the unit except the input terminals mounted LEDs indicating the presence and order of alternating voltage measured line phase. Available input terminals allow a voltage input unit for measuring one SCE of several lines simultaneously. You can connect to an external computer device. The device can operate in a local measurement network. In offline mode, you can memorize all the information in time continuous operation for more than two years.
