上圖顯示了15分鐘熱90%響應(yīng)時間的熱響應(yīng)特性。設(shè)置點確定了達(dá)到穩(wěn)態(tài)值90%的時間，就像模擬儀器的響應(yīng)時間一樣（響應(yīng)時間兩倍的穩(wěn)態(tài)值表示99%的值）。塊間隔此選項計算編程需求時間間隔內(nèi)的量（RMS電流、實際功率、無功功率或視在功率）的線性平均值。每個新的需求值在每個時間間隔結(jié)束時可用。滾動需求此選項計算編程需求時間間隔內(nèi)的量（RMS電流、實際功率、無功功率或視在功率）的線性平均值（與塊間隔相同）。該值每分鐘更新一次，并指示更新時間之前的時間間隔內(nèi)的需求。
The above graph shows the thermal response characteristic for a thermal 90% response time of 15 minutes. A setpoint establishes the time to reach 90% of a steady-state value, just as the response time of an analog instrument (a steady-state value applied for twice the response time will indicate 99% of the value). Block Interval This selection calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over the programmed demand TIME INTERVAL. Each new value of demand becomes available at the end of each time interval. Rolling Demand This selection calculates a linear average of the quantity (RMS current, real power, reactive power, or apparent power) over the programmed demand TIME INTERVAL (in the same way as Block Interval). The value is updated every minute and indicates the demand over the time interval just preceding the time of update.
