A Stored Energy Mechanism (SEM) is a mechanism that opens and closes a device (Switch) by compressing and releasing spring energy. The operating handle compresses a set of closing springs and a separate set of opening springs. These springs store the mechanical energy of this movement and are held in the compressed state by …

Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid. Electrical energy is stored during times when electricity is plentiful and inexpensive (especially from intermittent power sources such as renewable electricity from wind power, tidal power and solar power) or when demand is low, …

bcooney. Well, for each field that is unstored, you would have a twin that is a number not a calc. During a script that modifies the unstored, add a Set Field (stored to unstored) step. Use the stored fields in your dashboard. But perhaps just limiting the number of fields that display at any one time will be enough.

During sequential tripping of dc hybrid circuit breakers (HCBs), the energy-absorbing metal-oxide varistors (MOVs) are inserted one after the other rather than simultaneously. This tripping scheme has been demonstrated to be effective in reducing the peak fault current and fault interruption time. However, the voltage overshoots during the sequential …

Some MCBs are magnetic AND thermal, so they can trip on short pulses of high currents (short-circuit condition) and slowly rising currents (overload condition). If the MCB is of this type and the environment temperature is high, you can have it tripped on lower currents. There is a de-rate even when you place MCBs side-by-syde.
Unstored calculations happen whenever triggered such as loading a layout and making the field visible, or if a field within it changes value. Note that a SQL statement is not a field changing value. But the inputs to the SQL may be fields that would force a reevaluation. Script steps evaluate at the time they run.
