Delta Energy: Your Clean Green Solution for Superior Power Quality Assurance

Introduction

The explosion of industrial automation in the latter half of the 20th Century has brought untold benefit to today’s business processes, delivering convenience and cost savings from higher efficiency production and output.

But as with any ‘efficiency dividend’, what you gain on swings, you inevitably lose on roundabouts.

Indeed, our increasing dependence on energy-hungry automated processes is contributing to a host of systemic power distortion issues, leading to increased costs, protracted equipment downtime and dramatic energy losses that negate many of the efficiency gains of automation.

Facing years of economic uncertainty and rising energy costs, the need for high-efficiency, low-maintenance, automated processes is crucial to reducing costly overheads.

Moreover, as one of the top five per-capital greenhouse gas emitters in the OECD,1 New Zealand’s rising energy costs should give us greater cause to act on our corporate and ethical duty to minimise our carbon footprint.

Why Today's Electronics Pose a Threat to Automated Processes

As we bear witness to a progressively digital-dependent work space, power quality assurance has become vital to safeguarding equipment and systems essential to today’s industrial and commercial processes.

Until the 1960s, almost all electrical loads were linear, meaning that the AC current flowing through appliances created a perfect sine wave oscillation (sinusoidal current), causing no distortion to the local supply.2

The advent of modern electronics, which draw from mains power non-linearly, has proved a major source of damaging voltage fluctuations, reactive power events, and harmonic distortion.3

These drastic power fluctuation events contribute greatly to equipment failure rates, increased energy consumption and reduced lifecycles.

A particular bane of electrical engineers, the injection of harmonics – even in small quantities – can adversely affect electrical devices, overheating sensitive electrical components, including induction motors, transformers and capacitors.4

This unavoidable increase in harmonically disruptive loads – sourced anywhere from endpoint computers and printers to ‘big load’ and non-linear variable frequency drives (VFDs), heating/air-conditioning (HVAC) systems, uninterruped power supplies (UPS) and building lift systems – has resulted in flood of distorted (non-sinusoidal) current hitting the local grid.

Fight the Power: Finding the Right Solution for Your Power Distortion Woes

A quality load balancing solution or active power filter can mitigate the ill-effects of harmonic distortion and drastically improve power factor discrepancies.5 This will not only ensure operational stability of automated systems (i.e. preventing system stoppages, errors and alarms), but will reduce the stress and duty cycle on conductive components.

What’s more, a tailored energy management system can reduce and even regenerate energy consumed, increasing the overall efficiency of automation or building utility systems.

Today, there exist four key methods for improving power quality and efficiency, each with unique benefits to meet the needs of your business operations.
