Only the simplest powered electrical systems and equipment require just an on-off switch. In reality, most processes need a control system to manage commands and/or direct or regulate the behaviour of other devices or systems. Originally, these control systems would have been designed using Relay Logic which is a large array of hard-wired controls utilising […]

Variable Speed Drives (VSD) control motor speed in response to varying process demands in your plant. The motor speed adjustment can be based on feedback from the process; for example flow rate, temperature or pressure so that process control can be improved. Due to the ‘magic’ of affinity laws, small decreases in the speed of […]
Emergency Lighting is designed to ensure that if there is a power failure, there will be enough lighting to allow people to exit your building safely. The Australian and NZ Standard AS2293 outlines the level of light (lux) required to ensure people can exit safely from the building. Different levels of lighting may be required […]
Instrumentation is the term used to describe all the different devices (or instruments) that are indicating, measuring, and recording physical quantities within your plant to ensure that your production processes are operating effectively. Some types of measures commonly monitored include: Flow Flow meters are used to measure the flow in a process pipe. This […]

The third room is the safest because the lions would have died of starvation.
Equipotential bonding and earthing are essential parts of electrical safety. Both play an important part in preventing electrical shocks in your plant. Electrical equipment requires earthing to ensure that if a fault occurs that the voltage has a safe path to travel where the surge in current will trip a breaker, cutting power to the […]

Copper with its corrosive resistance, electrical conductivity and superior heat transfer make it one of the most important metals in use today. When it comes to the electrical industry, nearly all electrical wires and cables today use copper. This means that the increasing demand and pricing is having a significant impact on cable pricing. What […]
Circuit breakers can go long periods of time without activation. If they fail when activated, this can have catastrophic consequences for your staff and plant if an arc flash were to occur; and will certainly cause extensive damage to your electrical systems. Primary & Secondary injection testing should be included as part of your Preventative Maintenance […]
