IGS is a Waikato based company specialising in diesel generation.
We offer expert, fully independent advice on your diesel generator installation, upgrade or project.
IGS specialises in the control systems that automate your generator and control and interface with your site electrical systems.
IGS was started in 2012 to meet demand in the market driven by modern generator controllers.
Microprocessor based controllers are now found on nearly every modern generator and engine system, and with new tools required to install, test and modify these controls specialists trained to use and understand this equipment are required.
A generator has multiple systems on board, traditionally requiring different trades to understand and maintain it.
A diesel mechanic for the engine, a motor/generator winder for the alternator, an electrician for the electrical connections and more recently an automation technician for the control systems.
IGS brings all these skill sets into one company.
Using our knowledge base of trained generator technicians country wide we can bring you quality expert service to your installation for maintenance, modifications and fault finding and analysis.



The modern control systems used in generators has allowed new types of applications for generators that were previously unobtainable.
IGS works with its customers to develop and deploy these new systems.

Electrical lines company products: No break between generator and utility supply. This technology has been used for many years now using the Comap Combi software. IGS has developed a method of using this technology at high voltages (11-13kV), even when the disconnection point is many miles away from the generator connection and control area.

VSUP voltage support: Under heavy loads network voltages decrease as the current flowing in the supplying conductor rises. IGS has developed software and procedures to allow a generator to autonomously detect this voltage sag and correct it. No user intervention is required. This system is designed for areas where there is temporary high loads on the network, or maintenace is being performed.

Generator WAN Black box integration: IGS is working with customers to develop a single point interface for multiple generators spread across a wide geographical area. This allows for a common control system to call for network generation. This system allows for peak load limitation when a network is under pressure, by injecting kW where they are required, at the points of heavy use.
