By taking a holistic systems approach, we add value to every step and confidently help you transition from construction through to operations.
Integral Power’s Testing and Commissioning Engineers conduct thorough integration and functional tests on secondary circuits and validate that all circuits are fully operational, stable, and integrated per our client’s requirements. This process involves injecting current and applying voltage across primary equipment, followed by measurements and monitoring of corresponding secondary circuits to ensure all connected circuits’ end-to-end functionality and polarity.
Integral Power’s comprehensive functional testing covers a range of components such as Relay trip circuits, Electrical interlocks, Logic sequences, Alarms, HMI functions, Transformer cooling system operation, AVR and paralleling systems, Circuit continuity, Circuit Breaker Failures & Arc Flash busbar protection, SCADA Integration, Protection Scheme functionality, Functionality of Site ancillary services, and more.
Integral Power’s Testing and Commissioning Engineers utilize top-of-the-line, professionally calibrated testing equipment, which is fully traceable to a NATA-accredited body under ILCAS, to perform comprehensive testing and commissioning of your assets. The test results are compared against the FAT results, relevant Australian and international standards, and manufacturer’s publications during testing. If there are any discrepancies, our team investigates and rectifies them whenever possible and promptly reports any other issues to the client.
Our Testing and Commissioning Engineers conduct Integral Power’s Site Acceptance Tests (SAT) that cover the entire substation asset portfolio, including:
| Generators | Stator DC Winding Resistance |
| Power Transformers | Turns Ratio (TTR) |
| Current Transformers (CTs) | CT Polarity |
| Voltage Transformers (VTs) | VT Polarity |
| Earthing Systems | Soil Resistivity |
| Circuit Breakers | Static Contact Resistance |
| Busbars | Online Partial Discharge |
| Disconnectors & Earth Switches | Contact Resistance |
| Surge Arrestors & HV Bushings | Contact Resistance |
| Power Lines | Positive & Zero Sequence Impedance |
| High Voltage Cables | High Voltage Withstand (VLF) |
Integral Power’s Protection Engineers have a solid track record of setting up and testing modern Intelligent Electronic Devices (IED) and legacy electromechanical relays. Our engineers have worked with protection relays from various vendors such as GE, SEL, Alstom, AREVA, Schneider, Merlin Gerin, ABB, Siemens, Reyrolle, Eaton, Hitachi, CHINT, Basler, and more.
Protection relays are tested through secondary injection or other methods to verify that the programmed protection scheme operates effectively at the required thresholds and is suitable for its intended purpose. Our team provides a comprehensive and independently reviewed test report for each IED to establish its suitability and functionality per the protection design.
Integral Power’s Testing and Commissioning Engineers are well-trained in Protection Coordination and provide quick solutions and suggestions to address any problems or concerns that could impact the overall protection scheme, integration, or plant operation. Additionally, our commissioning personnel specializes in various communication protocols, including DNP3, IEC 61850, IEC 60870, CANBUS, and Modbus, in addition to SCADA and Protection System Commissioning.
Integral Power assists clients in ensuring that their high voltage assets comply with OEM-supplied datasheets even before the equipment is dispatched to the site. We conduct a complete series of Factory Acceptance Tests (FAT) and provide detailed documentation to the customer and witness the testing process. Our FAT testing coverage includes a broad range of testing, from general wiring tests to complete functional testing of protection relays/logic and communication to a SCADA master station simulator. As part of our FAT testing, we also revise and submit all the secondary documentation as “As built” to ensure compliance with the requirements.

Integral Power utilizes a suite of Inspection Test Plans (ITPs) for all commission engagements to document all necessary test instructions and expected outcomes. The actual test outcomes are then recorded in Inspection Test Reports (ITRs). Documented inspection and test procedures, plans, and records provide evidence of the test results supporting our issued test certificates.
To streamline our business processes and increase reporting efficiency, we utilize a robust field force automation (FFA) system that allows our commissioning engineers to digitally reference field test data to the corresponding ITPs using mobile handheld devices. This eliminates manual data handling and results in a more cost-effective testing and commissioning service for our clients.
All FFA devices are connected to a proprietary cloud application software that extracts field data, compares it against industry standards such as AS/NZS, IEEE, IEC, and NETA, and seamlessly generates draft test reports for our engineers to review and finalize.
Our FFA system is integrated with our more extensive automated work management system, which incorporates other Integral Power business functions. This structured and proven approach to testing and commissioning enables us to stay ahead of the competition while raising the industry standard. Additionally, our FFA system includes pre-built inspection and test plans (ITPs) and HV test templates for the entire HV asset portfolio, ensuring that our test documentation is consistent, compliant, and readily available to our customers.
