5-184 B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUALFLEXLOGIC CHAPTER 5: SETTINGS5A FlexElement is a universal comparator used to monitor any analog actual value calculated by the relay or a netdifference of any two analog actual values of the same type. The effective operating signal can be treated as a signednumber or its absolute value can be used.FlexElements run every half power cycle (every four protection passes).The element can be programmed to respond either to a signal level or to a rate-of-change (delta) over a pre-defined periodof time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold, asper your choice.
