Private Sector Good, Public Sector Bad? (2)

This is the second part of a look at former public services and utilities in Britain that have been privatised in the name of neoliberal economics and the mistaken belief that private enterprise is ALWAYS more efficient than publicly  run bodies.

Prisons

The first privately run prison in the UK was opened in 1992 under a Conservative government and private sector involvement in Britain’s penal system has grown steadily ever since. The UK is now second only to the USA in the number of privately run prisons.

Premier Custodial Group was formed in 1992 and in 2005 was the largest private company running UK prisons. It was a joint venture between the American private prison operator Wackenhut Corrections Corporation and the British firm Serco PLC. From a turnover of £7.52 million in 1994 it had increased its revenues to £127.4m, with pre-tax profits of nearly £10m, paying out a £2m dividend to shareholders. In 2002 Wackenhut was taken over by Group 4 Falck.

In 2003 Serco gained control of Premier, estimating that Premier's

 “income over the life of its existing contracts for five prisons, one secure training centre, two immigration facilities and court escort custody and electronic monitoring services was £2bn” (Cited in Prison Reform Trust: Private Punishment :Who Profits; January 2005)

Group 4 Securicor (G4S) was a company created in 2004 when Group 4 acquired Securicor. Since these takeovers these companies have gone from strength to strength, with Serco, G4S, and GEO Group branching into immigration and other services.

In 2018, the Guardian reported that the Home Office paid these companies:

 “hundreds of millions of pounds to run the UK’s immigration removal centres, but no one knows for certain just how profitable the industry is…Commercial confidentiality agreements mean the Home Office and outsourcing companies are not obliged to publish detailed financial information about immigration detention centres in the UK.” (Guardian: 10/10/22)

In 2022, one of these companies, Sodexo was awarded a £264 million UK prison contract over a ten year period. On receiving the contract, Paul Anstey, CEO, Government, Sodexo UK & Ireland stated:

“Our vision is to provide a secure and safe environment which reduces re-offending through education, builds new skills and offers respect, equality and inclusion.” (Facilities Management Magazine: 16/08/22)

If only that were true! As long ago as 2013 Sodexo Justice Services  was facing charges of prisoner torture and degradation.

'Cruel, inhumane and degrading': Female prisoner kept segregated in 'squalid' cell for five years.”  (Independent: 21/08/2013)

In 2016 a video of naked Prisoners pretending to be dogs led to an investigation into violence and humiliation of prisoners by Sodexo. In September 2017, a female prisoner died under Sodexo care. An inquest into her death concluded:

“serious failures at Sodexo run HMP Peterborough contributed to death of Annabella Landsberg”  (Inquest: 04/04/2019)

Another prison run by Sodexo was accused of residing over a “spice” epidemic, which led to the death of a male prisoner. (Manchester Evening News) In 2018 Sodexo was again accused of neglect and systematic failures resulting in the death of yet another inmate. In 2019, a different prison run by Sodexo was accused of “systemic breaches of inmate human rights”.

In February of this year 20 prison staff resigned from the Sodexo run HMP Lowdham Grange, which was deemed so unsafe the government was forced to take it over.

The appalling levels of service cited above are not restricted to Sodexo alone. In her book “Profiting from their misery: Britain’s private prisons”, Hatty Nestor reveals that:

“outsourcing companies like G4S encourage prisoners to work 40-hour weeks, all they are paid (is)  as little as £2 an hour. Such practices amount to slave labour. Companies are profiting from prison labour, paying fewer well-trained, low staff wages. In private prisons, staff are paid 23% less than public prisons, and they also outsource security, healthcare and cheap food. Private prisons aim for a profit margin of 8-10%, which is met by cutting costs and the increased exploitation of staff and inmates.”

Given that privately run prisons pay their staff less, are more overcrowded, and employ fewer prison officers you would think they would at least be more cost effective yet this isn’t the case. The governments own figures for 2022/23 reveal that it cost £32,762 per prisoner, per year in publicly run prisons, while the cost for privately run prisons was £33,628 per prisoner. (Ministry of Justice: “Costs per place and cost per prisoner by individual prison.", 21/0324)

 What is more, the government gives 23% of its allocated budget to private companies despite the fact their prisons only house 15% of the total prison population. It seems that whichever way you measure private prison success (apart form profits for its shareholders) private prisons do far worse than those still in the public sector.

Know About the Versatility and Efficiency of PM Fiber Splitters

Devices known as PM fiber splitters are made to divide an incoming optical signal into two or more output signals while maintaining the input signal's polarization. Specialized optical fibers that preserve the polarization of light passing through them are used to accomplish this. PM Fiber Splitter guarantees that the polarization state stays constant during the splitting process, in contrast to traditional fiber splitters, which are susceptible to polarization variations.

PM Fiber Splitters' Operation

An optical fiber that maintains polarization is the central component of a PM fiber splitter. These fibers are designed to direct and restrict light in a way that maintains the light's polarization condition. Usually, tension is added to the fiber core to do this, producing a birefringent effect. The fast and slow axes are the two orthogonal polarization states that occur from this splitting of light as it passes through the fiber. A birefringent element in a PM fiber splitter divides entering light into its fast and slow axis components as soon as an optical signal arrives.

Uses for PM Fiber Splitters

PM fiber splitters and PM PLC Splitter are utilized in fiber optic communication systems for signal splitting and routing in telecommunications networks. They are essential in spreading optical signals to several locations with the least amount of signal loss and impairments caused by polarization.

Sensing and Instrumentation: PM fiber splitters are used in many different types of instrumentation and sensing applications, including optical gyroscopes and interferometric sensors. Since polarization effects can create errors, their ability to sustain polarization makes them perfect for preserving the integrity of optical sensor systems.

Benefits

PM fiber splitters offer constant performance in polarization-sensitive applications by preserving the polarization state of input signals. This is one of its key advantages.

Low Insertion Loss: By reducing signal attenuation and increasing system efficiency, these splitters have low insertion loss.

High Reliability: PM fiber splitters have a solid reputation for durability and dependability, which makes them appropriate for long-term deployment in difficult applications.

Compact Design: Because PM Fiber Splitter usually has small sizes, it is simple to incorporate them into optical systems that already exist without taking up a lot of room.

How Switchgears Contribute to Power Quality and Equipment Longevity

In today’s industrial landscape, facility uptime, energy efficiency, and equipment lifespan are directly tied to power quality. Poor power quality doesn’t just inflate energy costs — it silently wears down critical machinery, causes unexpected shutdowns, and leads to costly repairs. One often overlooked hero in this equation is the switchgear. Modern switchgears do far more than just control and protect power circuits; they actively safeguard power quality and extend the life of your equipment.

In this article, we’ll explore the vital role switchgears play in maintaining power quality and ensuring long-term reliability in industrial and commercial facilities.

Understanding Power Quality: Why It Matters

Power quality refers to the stability, reliability, and cleanliness of the electrical power supplied to equipment. Factors that degrade power quality include:

· Voltage sags and swells

· Harmonic distortion

· Transient surges

· Frequency variations

· Imbalance between phases

When power quality is compromised, sensitive equipment like drives, motors, PLCs, and even lighting systems can suffer reduced lifespan, malfunction, or complete failure. High-quality power is not a luxury; it’s a necessity for operational efficiency and safety.

Switchgears: The Gatekeepers of Power Integrity

Switchgears serve as the nerve center of power distribution in any facility. Here’s how modern switchgear solutions help maintain and enhance power quality:

1. Voltage Regulation and Stabilization

Advanced switchgears monitor voltage levels in real time and protect equipment from harmful sags or swells. Features like automatic voltage regulation and voltage balancing ensure your sensitive loads receive stable power, preventing stress on motors and electronic devices.

2. Harmonic Filtering

Some modern switchgear systems come integrated with harmonic filters or support external filtering solutions. Harmonics generated by variable frequency drives (VFDs), UPS systems, and other non-linear loads can cause overheating and inefficiencies. Switchgears mitigate these distortions, protecting downstream equipment and improving overall energy efficiency.

3. Surge and Transient Protection

Switchgears equipped with surge protection devices (SPDs) act as the first line of defense against voltage spikes and transient surges caused by lightning strikes or grid switching events. This protection extends the life of connected equipment by shielding them from these destructive forces.

4. Fault Isolation and Selectivity

When a fault occurs, fast-acting circuit breakers within the switchgear isolate the problem area without disrupting power to the entire facility. This selectivity ensures that critical processes continue running while the fault is contained, preventing system-wide stress and downtime.

5. Power Factor Correction (PFC)

Switchgears can be integrated with power factor correction capacitors that optimize the power factor, reducing losses and improving voltage stability. A better power factor not only saves on utility bills but also reduces the strain on transformers and generators, thus enhancing their longevity.

Equipment Longevity: The Silent Benefit of Quality Power

The connection between switchgears and equipment lifespan is profound:

· Motors last longer when protected from voltage imbalances and harmonics.

· Transformers operate cooler and more efficiently when power factor is optimized.

· Variable Speed Drives (VSDs) avoid overheating when shielded from surges and harmonic distortions.

· Sensitive electronic controls avoid malfunction due to transient spikes and voltage dips.

In essence, well-maintained and properly specified switchgear reduces the electrical “stress” that causes premature equipment aging and failure.

The Shift Toward Digital and Smart Switchgears

The rise of digital switchgear takes power quality management to the next level. Smart switchgears offer:

· Continuous real-time monitoring of voltage, current, harmonics, and power factor

· Predictive analytics to forecast equipment wear and prevent failures

· Remote control and automated fault response for faster issue resolution

Facilities that embrace digital switchgear solutions can transform their maintenance strategies from reactive to proactive, leading to even longer equipment lifespans and lower total ownership costs.

Practical Steps: How to Maximize the Benefits

To harness the full power quality and longevity benefits from switchgears, consider the following best practices:

· Regular Maintenance: Inspect and test switchgear components to ensure optimal performance.

· Correct Specification: Choose switchgears rated for your facility’s load characteristics and future growth.

· Integration with Monitoring Systems: Leverage real-time data to track power quality indicators.

· Invest in Smart Solutions: Upgrade to digital switchgears with built-in diagnostics and analytics.

Conclusion: Switchgears as Strategic Assets

Switchgears are far more than circuit controllers; they are strategic assets that can directly impact your facility’s operational excellence. By stabilizing power quality, filtering disturbances, and protecting against electrical faults, switchgears extend the service life of every connected piece of equipment — from heavy-duty motors to delicate electronic controls.

For engineers, procurement managers, and facility operators, investing in high-quality, modern switchgear solutions isn’t just about compliance — it’s about securing long-term savings, boosting reliability, and optimizing performance.
