Introduction

This document is a common cybersecurity document cited in other SAC/TC104 publications, and includes information related to low-voltage applications. General information on network security measurement devices and related systems. With measuring devices (such as electrical quantity measuring and monitoring devices as defined in IEC 61557-12), power quality instruments (as defined in IEC 62586-1) The use of data acquisition, collection, and analysis devices (such as gateways and energy servers as defined in IEC 62974-1) is increasing, and the network... Network security risks are also increasing, especially with the growing use of interconnected devices in electrical installations. Therefore, facility managers limit risk by maintaining an acceptable level of information regarding facility and environmental strategies. To maintain maximum innovation... When designing devices, it is best to base them on risk assessment methods to ensure that they can withstand cybersecurity threats throughout their entire lifecycle. Used for power measurement and monitoring, power quality monitoring, Network security of data acquisition and analysis devices
