 Earthing Resistance & Conductor Size Estimators
Software tool to calculate the resistance of a grounding system and the dimensions required for a specific earthing resistance. The calculation process of this application is based on formulas obtained from BS 7430:2011 and IEEE Std 80-2000.

The calculations can account for:

  • Multiple Earthing Configurations (Rods, Plates etc.)
  • Uniform and 2-Layre Soil Type

 Q-Method for analysing DC Stray Current interference corrosion risk (Method that will be included in the upcoming ISO 21857 Standard)
The Q method will be included in the upcoming ISO 21857 Standard. It can be used for evaluating the time varying potentials to allow a judgement of the pipelines’ corrosion risk caused by dc interference.

The method can be used to evaluate:

  • Measured current densities
  • Measured potentials

Risk Assessment Tool for Lightning Impact on
Buried Gas Pipelines

Software Use:
Limited to DESFA, SA Greece

 Risk Assessment Tool for Lightning Impact on Buried Gas Pipelines
Software tool to perform lighting risk assessment on buried pipeline systems.

The risk assessment tool calculates the following probabilities under episodes related to direct lightning strikes in the adjacent soil:

  • Probability to have some coating defect on a buried gas pipeline section.
  • Probability for the buried pipeline section, to be located within a critical soil ionisation
    zone
  • The probability to have some metal-wall defect on a buried pipeline section

AMPACITY Software for
Bare Overhead Conductors
and Bare Buried Conductors

Software Use: Limited to ELEMKO, SA
Email: elemko@elemko.gr

 AMPACITY Software for Bare Overhead Conductors and Bare Buried Conductors
A computer program with G.U.I that provides the minimum conductor size, the conductor ampacity or the conductor temperature rise of bare buried conductors during a fault. For bare overhead conductors the software computes the conductor temperature when the electrical current is known or the current that yields a given maximum allowable conductor temperature. The calculations rely on IEEE std 738-2012 and on IEEE std 80-2013.

The Overhead Conductors can handle three input data sets that account for:

  • Weather Conditions
  • Conductor Characteristics
  • Computation Data

The Buried Conductors module can handle three input data sets that account for :

  • Computation Data
  • Material Constants
