質問 2：
Since electric delivery companies are required to maintain line frequency within a very narrow tolerance (< 0.1%) and to rapidly implement corrective action to repair out-ofbounds conditions, Real-time Monitoring (RTM) has been deployed to monitor line frequency measurements that are retrieved from key power distribution points every second. Which two metrics are appropriate for an RTM dashboard object where the data is refreshed every five seconds? (Choose two.)
