Gas Discharge Tube Holdover Voltage Calculator
Audit recovery voltage/follow current against caller GDT holdover rating and explicit waveform applicability; does not predict extinction from sparkover or establish safe surge protection.
Description
GDT holdover evidence depends on recovery voltage, follow current and waveform applicability.
GDT holdover evidence depends on recovery voltage, follow current and waveform applicability. Margin alone is insufficient.1
Enter positive holdover rating/follow-current limit, nonnegative recovery voltage/follow current and applicability boolean. Return signed voltage margin and inclusive combined evidence gate.
When to use Gas Discharge Tube Holdover Voltage Calculator
Use Gas Discharge Tube Holdover Voltage Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No arc recovery, surge protection design or electrical-safety approval is provided.
Prepare measured device or circuit evidence with matched frequency, temperature, waveform and calibration conditions. Supply explicit caller ratings and limits.
How to use Gas Discharge Tube Holdover Voltage Calculator and understand its results
- Prepare measured device or circuit evidence with matched frequency, temperature, waveform and calibration conditions. Supply explicit caller ratings and limits.
- Enter observedRecoveryVoltageV, callerRatedHoldoverVoltageV, callerObservedFollowCurrentA, callerFollowCurrentConditionLimitA, ratingAppliesToCallerWaveform using the field table and calculation rules, then run the tool.
- Read signedHoldoverVoltageMarginV, withinSuppliedHoldoverEvidence. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedRecoveryVoltageV | Observed recovery voltage v | number | Required |
| callerRatedHoldoverVoltageV | Caller rated holdover voltage v | number | Required |
| callerObservedFollowCurrentA | Caller observed follow current a | number | Required |
| callerFollowCurrentConditionLimitA | Caller follow current condition limit a | number | Required |
| ratingAppliesToCallerWaveform | Rating applies to caller waveform | boolean | Required |
Enter positive holdover rating/follow-current limit, nonnegative recovery voltage/follow current and applicability boolean. Return signed voltage margin and inclusive combined evidence gate.
margin=ratedHoldover−recovery; gate=waveformEvidence and voltage≤rating and followCurrent≤limit Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedHoldoverVoltageMarginV | Signed holdover voltage margin v | number |
| withinSuppliedHoldoverEvidence | Within supplied holdover evidence | boolean |

}Limitations and assumptions
No arc recovery, surge protection design or electrical-safety approval is provided.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Optocoupler Isolation Voltage Calculator: Optocoupler working voltage and isolation-test voltage describe different conditions. Test voltage is not a continuous working rating. For a complementary task, use Thyristor Holding Current Calculator: A holding-current model stays released after its first drop below threshold. A later current rise does not automatically retrigger the device.
