Electrical engineers available for journalists
Brunstock welcomes contact from journalists and the media about our area of expertise—primary and secondary substation ehouses and kiosks that contain medium voltage switchgear (MV GIS), high voltage switchgear (HV GIS), ring main units (RMUs), SF6-free switchgear, circuit breakers and transformers.
Our distributors service the renewables; utilities; infrastructure; and mining industries with power transformation solutions to suit their project timeframes and budgets. Brunstock’s leadership team has a deep understanding of power engineering and manufacturing, which enables them to connect world-class renewable energy products with the industries that need them.
As a relationship and sustainability-focused organisation, Brunstock is committed to delivering high quality substation equipment that prioritises renewables and the environment. This involves ensuring that the factories we have partnered with are certified with ISO 9001 quality management systems, ISO14001 environmental management systems and ISO45001 workplace health and safety management systems; and choosing like-minded businesses throughout our supply chain and distribution network. The substation packages we offer adhere to all the latest IEC and will be customised to your customer’s standards.
Further information
As enthusiastic participants in the energy transitions that are going on around the world, Brunstock prides itself on being part of the solution. Our power transformers solve problems for EPCs (engineering procurement and construction companies) by helping our distributors deliver an end-to-end solution, not just a single product. Our products are designed for government departments, NGOs, consultants, electrical contractors, power utilities and small-scale solar companies on utility scale renewable projects.

You are welcome to contact us for any specific requirements and opportunities. Outsiders to the electrical industry may benefit from perusing our transmission and distribution definitions below.
Transmission and distribution definitions
AIS: Air insulated switchgear
APS: Air insulated primary switchgear
AS/NZS: Australian Standard/New Zealand Standard
BESS: Battery energy storage system
CAPEX: Capital expenditure (business expenses that include fixed assets, such as land, buildings and equipment)
CB: Circuit breaker
CT: Current transformer
Curtailment: Reducing the production of energy due to having too much in supply (also called spilled energy)
DRE: Distributed energy resources (such as rooftop solar, but also commercial and industrial BESS). Distributed PV (solar) would typically be <1MW.
DK: Distribution Kiosk
Ehouse: Ehouses are prefabricated transportable substations (people can walk between two corridors of equipment)
EIS: Environmental impact statement
EPC: Engineering, procurement and construction. Relates to finance/services/contracts etc. (TGOOD website, contracts)
ES: Energy storage (also see BESS)
FAT: Factory acceptance test
FPP: Fatality prevention protocols
GA: General arrangement drawing
GIS: Gas insulated switchgear
Grid: a network of electrical transmission lines that connect power generating stations to consumers
GW: Gigawatts (1000 MW)
HGIS: Hybrid gas insulated switchgear (not to be confused with high voltage GIS, which should be denoted HVGIS, not HGIS), also could be HPS for hybrid primary switchgear
HPC: High power charging

Microgrid: A self-contained electrical network that allows you to generate your own electricity on-site
MV: Medium voltage
MV AIS: Medium voltage air insulated switchgear
MV GIS: Medium voltage gas insulated switchgear
mW: milliwatts (0.001 watts), not to be confused with MW
MW: Megawatts measure power (1,000,000 watts)
NCR: Non-conformance report (when a failure to comply or a defect in a management system is detected)
Network: In the context of electrical engineering, the word ‘network’ could mean anything from the electrical connections of a specific site to the entire power grid of a city or other place.

OHS: Occupational health and safety (see WHS)
PCS: Power Conversion System
PO: Purchase order
PPAs: Power purchase agreements
PS: Primary switchgear
PV: Photo voltaic (solar power)
RE: Renewable energy
REZ: Renewable energy zone, an area intended to provide renewable energy hosting capacity at scale (Simshauser, 2024)
RFQ: Request for quote
RMU: Ring main unit, which is a medium voltage cabinet for integrated electrical equipment to connect, measure and integrate fixed type breakers, with a transformer protection function. RMUs are connected through SCADA system using a RTU and a modem for communication.
RTU: Remote terminal unit. RTUs convert analog signals to digital and vice versa. RTUs receive and send information about RMU devices to HMI (human machine interface) systems. Commands from the control centre are received by RTUs and respective actions take place without the help of a human operator.
SCADA: Supervisory control and data acquisition. It is a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data.
SF6: Sulphur hexafluoride (a greenhouse gas)
Skids: Platforms substations can be built on when they are unitised or containerised, which takes up less space that traditional substations
SLD: Single-line diagram
SMP: Safety management plan
SMS: Short messaging service (text message sent from mobile phone)
SQE: Supplier quality engineer
SS: Secondary switchgear
Substations: Vital for power systems as they transform and switch voltages for different purposes.
SVG: Static voltage ampere reactive (VAR) generator
Switchgear: Broadly speaking it is a piece of transmission and distribution equipment that switches electrical power on and off. Eg. BGS-12 and BGS-40.5, BGP-40.5
