A FlexElement is a universal comparator that can be used to monitor any analog actual value calculated by the relay or a
net difference of any two analog actual values of the same type. The effective operating signal could be treated as a signed
number or its absolute value could be used as per user's choice.
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 period
of time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold as
per user's choice.
