When it comes to electrical engineering, a customised maintenance plan is the key to a safe environment and a long life-span for your equipment.
We specialise in delivering end to end solutions for high voltage engineering, including earthing systems, protection design, and lightning protection. We provide complete design and project management services from inception to completion, throughout all voltage ranges.
Protech Energy Group’s engineering staff are considered industry experts for network consulting and reinforcement. They are regularly sought after by OEMs to solve complex electrical engineering issues.
Design & Consulting
We provide the full range of design services, from preliminary conception through to design, planning and construction phases of a wide range of schemes.
Our engineering team can undertake all aspects of high voltage electrical substation design. From early planning and investigation to project management of plant installation within live substation environments.
Project Management & Procurement
Our team of Engineers and Project managers can manage your project from conception to completion, from minor augmentations to major projects for both brownfield and greenfield sites.
Our range of project management, construction management, contract administration and site superintendent services will ensure your project stays on budget.
HV Audits, Engineering Compliance, Owners Engineer Services & RPEQ Certification
HV Audits are required for new or Altered Installations to minimise the risk to people, plant and equipment, environment from the normal and abnormal operation of High Voltage Equipment. Protech has fully qualified and experienced HV auditors to carry out HV Audits through Design Examination and Physical Site Audits.
Owner’s Engineer serves as an independent representative or advocate of the project owner. It is a critical supporting role that provides project management and quality assurance support during all stages of the asset lifecycle. High quality in the planning and construction of a plant is important for its safety and long-term reliability. Engaging Protech as an independent owner’s engineer can ensure that your project complies with international standards, thereby reducing the risk of liabilities and address potential quality issues. In addition, we can help to reduce your project’s costs through greater control over the project scope, schedule, orders, and various other aspects.
Protech has experienced in-house RPEQ engineers to provide RPEQ design and certification and Third-party validation of design.
PROTECTION DESIGN, PROTECTION COORDINATION STUDIES AND LIGHTNING PROTECTION
Protech provides comprehensive solutions for Protection Design and Coordination Study, Relay Upgrades and Advanced Protection Testing services.
We will model all protective devices in your system and carry out a comprehensive Protection coordination study to ensure all electrical equipment is adequately protected against overloads, fault currents & earth fault, evaluate and confirm adequacy and performance of Protection CTs. We confirm coordination between upstream and downstream devices using graphical Time Current Curves (TCCs) and sequence of operation analyser to avoid and eliminate costly spurious trips in the power system. Determine optimal settings of all protective equipment and evaluate impacts of motor starting on Protection settings and calculate relays settings to cater for impacts of in-feeds and mutual couplings in parallel and Tee -feeders for HV & EHV systems.
Protech Engineering’s highly developed expertise in lightning Protection systems design allows us to work with you to develop cost-effective designs, ensuring your new and existing assets are protected from the harmful effects of lightning strikes. We carry out Engineering studies and design, compliance standards and system testing and inspection.
Arc Flash Studies
An arc flash hazard analysis is critical to the safety of plant personnel working on or near exposed energized electrical equipment. Protech Arc Flash analysis will quantify the release of thermal energy associated with potential arc flash hazards and will describe safety recommendations such as establishing protection boundaries and specifying protective equipment for personnel.
PEG’s highly qualified and experienced Engineers have performed numerous arc flash studies for all types of industries. We use of commercial software utilizes IEEE and NFPA equations and methods for comprehensive and accurate calculations, including fault current momentary duty, device clearing time, arcing fault currents, duration of arc and incident energy, analysis and develop recommendations in a comprehensive written report.
Protech Engineering expertise and methodologies give you the confidence that your earthing system, small or complex, will function as intended.
Protech Engineering specialises in the engineering studies and design, modelling, testing of earthing systems, and developing cost-effective mitigation solutions. Earth testing is carried out to ensure compliance with the design criteria and requirements mandated in AS3000 and AS2067. Our test engineers utilise industry’s leading current injection methods and latest analysis technology to assess soil resistivity, earth resistance, touch and step potentials associated with your earthing systems.
Upon completion of the tests, we provide you with a detailed test report that includes analysis, test methodology, results obtained and expert recommendations. These reports would form the basis of your asset management plans and will support any future auditing process. Our earth testing service includes Soil Resistivity, Earth Resistance, Voltage Contour Measurements, Step and Touch Potential, Earthing Continuity Checks, AS3000, AS2067 & ENA-EG1 based Inspections.
SPECIALIST ENGINEERING SERVICES, FAULT INVESTIGATION AND ROOT CAUSE ANALYSIS
Types of failure include Power Transformers, High voltage cable, and termination failures, Inadvertent protection tripping, Electric shocks and incidents, High voltage switchgear, switchboard faults. PEG engineers have considerable experience and expertise necessary to adequately investigate electrical equipment failures.
We gather all relevant data including test reports, SCADA logs, operator notes, protection relay event records and piece information time sequence chronological order to determine the root cause of the failures and trips.
Protech Engineers are highly sought after by high-value clients for their technical expertise on complex engineering issues fault investigations and regularly provide this expertise to Mining and Infrastructure – utilities, generation and Manufacturing industries.
Design & Consulting
Protech provides comprehensive Electrical designs and schematic CAD drawings for various electrical projects to the client’s requirements.
Our team of Electrical Engineers and CAD designers have wide-ranging industry experience of HV and LV electrical designs and schematics, electrical site plans, general arrangement drawings for plant and equipment layout, sizing of transformers, switchgear, HV equipment’s, bus duct, and single line diagrams for electrical distribution systems.
We provide expert engineers for site visits to existing installations, provide redline mark-up drawings of existing systems and convert to As-Built drawings to accurately reflect the existing as-installed status of your plan and equipment and electrical systems.
Advanced Testing & Commissioning
Proper commissioning and periodic testing of high voltage equipment are vital to the longevity of your valuable assets. Research shows that improper commissioning along with “set-and-forget” mentality has been the leading causes of premature failures.
Protech Engineering offers a comprehensive range of testing and commissioning services so you can ensure that your assets have been installed properly and are performing to the required standards for operation. With state-of-the-art in-house test equipment, our test engineers can provide you with a comprehensive suite of construction, commissioning and condition monitoring services for all industries and high voltage equipment. Our high voltage condition monitoring services, you can enhance the reliability and longevity of your assets.
