Engineering Services

Power Protection Industries offer specific RPEQ engineering design services for energy management, power quality and lightning protection.

PPI offer the following services:

Design of High Voltage Switchyard & Substation Earthing Systems

  • Site soil resistivity testing and computer analysis and design using the industry leading software package CDEGS by SES Technologies.
  • Earthing design to achieve safe step and touch potentials in accordance with the Australian substation earthing guides - ENA EG-1 (IEEE Std 80), ENA EG-0, and AS/NZS 2067.
  • High voltage substation earth system testing using low current, off-frequency current injection testing (CIT) methods, with tuned voltmeters to measure step and touch voltages.
  • Earthing and grounding design services for specialised applications, such as large scale solar PV arrays, wind turbine generation, including analysis of earth potential rise and lightning transient effects.

Lightning & Surge Protection Design, Audits & Site Inspections

  • A specialised system design service for the protection of facilities against direct lightning strikes, in accordance with national and international standards.
  • Lightning risk assessment calculations in accordance with AS/NZS 1768 and IEC 62305-2.
  • Application of surge and transient protection to power and communication systems in commercial and industrial facilities.
  • Provision of computer modelled lightning protection designs, and standard compliant design specifications for tender documents.
  • Specialised lightning protection earth system modelling of lightning induced earth potential rise.

Power System Load Profile Analysis & Power Factor Correction Design

  • Power system analysis, including identification of harmful harmonics and power system disturbances.
  • Designs for the installation of LV and HV power factor correction equipment to improve efficiency, reliability and voltage stabilization within the power system.
  • Electricity bill assessment (kW, kVA and kVAr) for cost savings under existing and future electricity tariffs, with recommendations on how to implement savings measures.
  • Calculation of savings in greenhouse gas emissions, due to the reduction in kVA demand achieved by power factor correction.
