Considerations for selecting Power Factor Correction

Power Factor Correction (PFC) is one way facility and plant managers can reduce energy costs by eliminating charges for inefficient power usage. In the previous article, we looked at power and maintenance cost benefits of PFC, improving load balancing and site Power Factor, along with different types of PFC. Here, we continue the discussion as we delve into active harmonic filtering and electronic VAR control, installation considerations along with potential payback benefits.

Design considerations for Human Machine Interfaces

Deciding to purchase and install a Human Machine Interface (HMI) can be an expensive exercise if not undertaken with due diligence, so it’s important to select one that is suitable for your application. With a range of different hardware options to choose from, it can be overwhelming to know what to start looking for. Here, we look at size, environmental conditions, materials, IP ratings and outdoor considerations that you need to think about during the initial design process.

Reducing energy costs with Power Factor Correction

Large businesses and industrial operations consume large amounts of energy, making power one of the biggest costs for owners. On top of regular daily power charges, many network providers charge these businesses for the demand they place on the electricity grid. For owners and site managers looking to reduce power bills, this means it is now more important than ever to manage their site’s power consumption and importantly the Power Factor (PF). Here, we will look at the power and maintenance cost benefits of Power Factor Correction (PFC), improving load balancing and site Power Factor along with types of PFC.

Considerations when selecting a data historian

In the first part of this article, we looked at the functions of data historians, how they can help improve operations and different types of historian available. Here, we continue the discussion, taking a closer look at some of the major vendors, the licensing options and the benefits of selecting a suitable data historian system relevant to the industrial control industry.

Data aggregation using historians for informed decision making

Historian systems have become increasingly popular throughout various industries for their ability to provide operations managers with the data needed to operate and manage their assets efficiently. In the first of two historian articles, we look at what a data historian is, the different types of historians available and some of the hardware requirements.

Using PLCs in cathodic protection systems

Corrosion of steel and reinforced concrete in structures such as bridges, jetties, shipping vessels and pipelines can lead to catastrophic failures if not maintained correctly. Employing the use of an appropriate corrosion mitigation method will reduce damage to the structures, increasing their operating life and lowering maintenance costs. Impressed current cathodic protection systems are one of the most effective methods of mitigating corrosion in metal and concrete reinforced structures, however these systems can be complex so must be designed and implemented correctly.

Reducing risks and increasing SCADA network reliability

In previous articles, we looked at different types of networks, security, redundancy, cable types and how to best leverage your network. In this article we continue to explore crucial aspects of SCADA networking, including environmental risks and their impact on reliability, as well as some different networking product options.
