High voltage electrical services
SPS covers the full life of your high and low voltage assets: design, testing and commissioning, switching, and ongoing maintenance and diagnostics. Not sure which service you need? Call 1300 425 498 and talk to an engineer.
Testing & Commissioning
Testing and commissioning confirms that new, upgraded or modified electrical equipment has been installed correctly and performs as designed before it is energised and put into service.
Testing & Commissioning detailsTypical scope
- Switchgear testing and commissioning
- Protection relay programming, testing and commissioning, including Schneider and SEL relays
- Power transformer testing
- Voltage transformer (VT) and current transformer (CT) testing
[TODO: client to confirm scope]
High Voltage Design
High voltage design covers the engineering of the primary (power) and secondary (protection, control and metering) systems that make up a substation or private HV network.
High Voltage Design detailsTypical scope
- Primary substation and switchroom layout design
- Secondary systems design (protection, control and metering)
- Power system studies, such as load flow and protection studies
- Design documentation and drawings

High Voltage Switching Services
High voltage switching is the controlled operation of HV switchgear to isolate, earth and restore parts of an electrical network so that work can be carried out safely.
High Voltage Switching Services detailsTypical scope
- Planned HV switching and isolation
- 24/7 emergency switching response
- Isolation and earthing arrangements for work on HV equipment
- Restoration of supply after work

Maintenance & Support Services
Electrical systems need regular attention to stay safe and reliable. Maintenance and support services keep HV assets in good condition and help find problems before they cause an outage.
Maintenance & Support Services detailsTypical scope
- Preventative maintenance programs
- Inspection and testing of HV switchgear and transformers
- Troubleshooting and fault-finding
- Maintenance reports and recommendations

Earth Testing
A compliant earth system is essential for the safe operation of high voltage distribution. If a fault occurs, the earthing system must carry fault current safely and keep the voltages people could touch within safe limits.
Earth Testing detailsTypical scope
- Soil resistivity testing
- Earth resistance testing
- Step and touch potential testing
- Compliance verification and reporting

Thermographic Imaging
Infra-red (thermographic) imaging scans electrical switchgear and cabling for excess heat. Thermal images give an instant indication of all manner of potential problems in connectors, switches and fuses.
Thermographic Imaging detailsTypical scope
- Infra-red scanning of switchgear, cabling, connections and fuses
- Identification of hot spots and potential faults
- Thermal images with findings and recommendations
