Lighting emergency gear – what waveform should we use?

This article explains the pitfalls in providing DC or a modified sinewave to drive LEDs in emergency mode. Many LED luminaires have built-in drivers, so emergency gear must either simulate mains or attempt to drive the LED with DC power. Lower-power LEDs with low power factors are easiest to drive due to their simple circuitry. […]

Register now for the 2019 SAIEE national conference

South Africa’s energy crisis demands an all-hands-on-deck approach that embraces the necessary change we need. We know that local government and utilities have a critical role to play in how we shape our energy future. The question is, how do empower municipalities and utilities to lead the way? Join us at the SAIEE National Conference, […]

SABS: Industry to use independently verified, type-tested switchgear only

Both local and international standards have been amended since 2015 and this has created confusion in term of the compliance requirements of low-voltage switchgear. Inadequate testing and purchasing of untested products can have dire consequences to the supply of electricity. The South African National Standards (SANS) that apply to switchgear have been adopted from the […]

The fourth industrial revolution: Are we fit to face the future?

Rapid urbanisation, demographic and social change, climate change and resource scarcity, technological breakthroughs in the energy sector, and economic shifts are major disruptors in South Africa’s energy and social structures. The fourth industrial revolution is likely to introduce disruptive elements to every aspects of our lives. The generation, distribution and sale of electricity will not escape […]

Public lighting: Lighting the way to smart city development

Public lighting is one of the services most visually seen by the general public within a city (though it almost goes unnoticed). Lighting provides a sense of visual safety and security. This improved sense of safety and security will often lead to an increase and further promotion of community activities, events, sport, trade, industry and […]

Anticipating silicon solar cells with significantly improved efficiency

Theoretical calculations indicate that under certain conditions silicon can endow solar cells with a much higher efficiency. Small silicon clusters may provide a source of accordingly modified silicon. However, to date these clusters have not been accessible in soluble form, a prerequisite for flexible processing. Researchers at the Technical University of Munich have now discovered […]
