—

Result Interpretation

Microgrid Relay Coordination Timing Gap calculator computes Protection coordination gap in s using the defined engineering formula and the input values provided. Protection coordination gap is expressed in s. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Upstream relay operating time = 0.3
  • Downstream relay operating time = 0.1
  • Minimum required coordination time margin = 0.15

Expected Result:

  • Protection coordination gap = 0.05

Engineering Interpretation:

Under the given input conditions, the calculated result is: Protection coordination gap = 0.05 s.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
