Calculator

Quick electrical engineering calculations without requiring an event recording.

Line / Phase Voltage

L-N to L-L conversion and individual phase calculations.

Input

Conversion L-N magnitude Unit

Balanced mode assumes balanced three-phase quantities with 120° phase displacement.

Formula

Individual mode uses complex phasor subtraction. It does not use √3 × phase magnitude for unbalanced entries.

Power & Current

Power, current, and power-factor calculations for common electrical engineering use cases.

Input

System Type

Voltage (VLL) Unit Apparent Power (S) Unit

Current

Formula

Notes

Use Single-phase for I = S / V. Use 3-phase L-L for I = S / (√3 × V_LL), where V_LL is the line-to-line voltage.

Input

Active Power (P) Unit Reactive Power (Q) Unit Apparent Power (S) Unit

Enter any two of P, Q and S. The third is calculated and never overwrites a value you typed.

Result

Quantity	Value	Source

Formula

Notes

S² = P² + Q². When Q or P is calculated from S it is returned as a magnitude, because its sign cannot be recovered from S alone. PF = |P| / S.

Input

Power Factor

Power Factor Type

Active Power (P) Unit Reactive Power (Q) Unit Apparent Power (S) Unit

Enter the power factor and exactly one of P, Q or S.

Result

Quantity	Value	Source

Formula

Notes

Lagging / inductive: Q is positive. Leading / capacitive: Q is negative. PF must be greater than 0 and no more than 1; at PF = 1, Q = 0.

Time Axis Setup

Configure how time is interpreted from the selected column.

Advanced Options ▸

Reconstructed Time

Use when timestamp precision is insufficient or repeated timestamps need to be reconstructed using the recording interval.

Example: a 50 Hz recording contains many repeated timestamps such as 18:04:00, 18:04:00, 18:04:00, even though samples were actually recorded every 20 ms.

Manual Interpretation

Use when the recording time cannot be represented by the standard time formats and needs an engineer-defined interpretation.

Example: a vendor exports a custom timestamp format that Powerwave cannot detect automatically, so the engineer must explicitly define how the time information should be interpreted.

Time format: Not set
Time column: None selected

Time Format

Time format

Select a time format above, or use one of the Advanced options below, to configure this source.

Time column

Use Manual Interpretation only when the recording's time structure cannot be represented using the standard formats above. It is an engineer assertion, not a detected reading, and cannot be converted to Powerwave directly.
