Archer Electrical Engineering turns electrical theory into solutions that work.

Services

Power System Analysis & Planning

AEE is committed to understanding the role that electrical power plays in the business of every one of its clients. Our experience of power system planning is that most customers know what they want. What they actually want to know is whether or not their plans will work. That is where AEE can help.

Protection Scheme Design

AEE provides secondary system designs for the protection and control of power system plant components such as, generators, transformers, cables, overhead lines, busbars, capacitor banks, reactors, motors and power converters.

Protective Device Settings

AEE has a wide ranging experience in setting relays over all three generations of relay technology: electromechanical, solid state electronic and programmable numeric relaying.

Arc Flash Hazard Analysis

Safety conscious operators need their electrical workers to be fully informed of the potential hazards posed by electrical arcing faults. AEE’s arc flash hazard analysis will identify areas of high risk.

Earthing Design

Competent earthing design is a key component of substation safety. AEE identifies the relevant generic case studies provided in Australian Standard, AS 2067:2016 to assess acceptable levels of step and touch potential.

Other Services

NER Services, Expert Witness, (Grid) Access Applications, HV Submissions, Relay Maloperation Investigations, Power Quality Investigations and Drafting are among the other services AEE provide.

Projects

Switchgear Short Circuit Rating Studies

This Power Station was designed in the 1970’s when the fault current contribution made by induction motors into short circuits was not widely recognised.

Process Plant Protection Settings

When construction of a $60 billion LNG plant commenced, AEE was chosen to provide the time graded protection settings for the entire power system from the 240 V lighting and small power circuits up to the 150 MW gas turbine generators.

Process Reliability

When this gold mine operator contacted AEE gold production was punctuated by unexplained MCC outages in the processing plant. After visiting the facility and meeting the electrical staff AEE developed the following remediation work package for application in each of the plant’s substations.

Protection Maloperation Investigations

Protection maloperations happen and the effects can sometimes be costly. AEE has successfully completed investigations into unexplained switchgear operations at power stations, substations and motor control centres.
