Practical Engineering Solutions: Concrete Approaches to Addressing Industrial Electrical and Instrumentation Challenges

Modern industry relies on precision, safety, and efficiency. Nothing provides a better foundation for this than well-designed electrical and instrumentation (E&I) systems. But regardless of the technology used, real-world operations always hold surprises. From unforeseen power outages to harsh environmental conditions, practical challenges require equally practical engineering solutions.

At Jemmatech Engineering Consultant, we believe that the true value of our engineering services lies in solving real-world problems with practical and sustainable solutions. We’ll show you how experienced engineers approach real-world scenarios and the lessons each industry can learn from them.

The Industrial Backbone: Understanding Electrical and Instrumentation Systems

In every industrial facility, E&I systems are inextricably linked. Electrical systems distribute energy and power to motors, pumps, control panels, and safety devices. Instrumentation systems, on the other hand, measure and control critical variables such as flow, pressure, temperature, and chemical composition, ensuring safe and efficient processes.

A failure of any of these systems can have consequences ranging from simple production interruptions to serious safety incidents. Solutions must therefore be both technically sound and practical.

Practical Scenario 1: Power Quality Issues in High-Precision Manufacturing

Industry: Pharmaceutical Manufacturing Facility

Problem:

In a pharmaceutical facility producing injectable medications, precise temperature control is crucial. During peak hours, voltage dips in the power grid affected the variable frequency drives of the critical HVAC systems, causing sudden shutdowns that resulted in temperature spikes in the cleanroom and necessitating the disposal of multiple batches of medication.

The Jemmatech Solution:

Power Quality Audit

• Engineers installed power quality analyzers for a 30-day study to detect voltage dips, surges, harmonics, and transients.
• The voltage dips correlated with the startup of large chillers in a nearby industrial park.

Installation of a Dynamic Voltage Restorer (DVR)

• Jemmatech specified DVR units capable of injecting a compensating voltage within milliseconds to ensure the stability of sensitive loads during voltage dips.

Isolation of Critical Loads

• Redesign of the electrical distribution system so that HVAC systems and critical instrumentation are powered by isolated power supplies with backup UPS.

Result:

No shutdown of the HVAC systems in the clean room 12 months after installation.

Reduced product losses, saving approximately $2.8 million per year.

Realistic Scenario 2: Instrumentation Signal Degradation in Harsh Environment

Industry: Offshore Oil and Gas Platform

Problem:

On an offshore oil platform, a critical pressure transmitter sending a 4-20 mA signal to the control room was producing erroneous readings. Intermittent spikes occurred, triggering unnecessary shutdown alarms and causing hundreds of thousands of dollars in lost production.

The Jemmatech Solution:

Root Cause Analysis

• Engineers traced the signal cables and discovered they ran alongside high-current cables for large motors.
• The cables were also exposed to heavy salt spray, which accelerated corrosion at the connection points.

Signal Isolation and Cable Replacement

• The existing copper cable was replaced with fiber optic cables that are immune to electromagnetic interference (EMI) and corrosion.
• The installation of IP66/NEMA 4X stainless steel junction boxes ensures protection from marine conditions.

Improved Grounding

• A central grounding point was installed to eliminate ground loops that cause signal spikes.

Result:

• Complete stabilization of the pressure signal.
• The platform was able to avoid repeated unplanned shutdowns, saving approximately $1.2 million in production losses per year.

Practical Scenario 3: Integrating Existing Systems with New Digital Platforms

Sector: Food Production

Problem:

A food processing plant was using legacy programmable logic controllers (PLCs) dating back to the early 1990s. Management wanted to integrate plant data with a modern manufacturing execution system (MES) to monitor performance in real time and enable predictive maintenance. However, the legacy PLCs used outdated communication protocols, incompatible with modern Ethernet networks.

The Jemmatech Solution:

Protocol Conversion

• Installation of industrial protocol converters converting legacy serial protocols (Modbus RTU) to Ethernet/IP, enabling communication with modern systems.

Phased Upgrades

• Identification of critical areas for PLC replacement (areas where spare parts were unavailable).
• Development of a phased plan for replacing legacy PLCs during scheduled maintenance periods.

Implementation of Digital Twins

• Creation of digital twins of production lines from existing data to enable virtual testing before physical system integration.

Result:

• Real-time monitoring of production indicators without a complete and costly system overhaul.
• Overall Equipment Effectiveness (OEE) increased by 9% in six months.

Case Study 4: Ensuring Functional Safety

Sector: Chemical Production

Problem:

A chemical plant handling hazardous materials needed to comply with the functional safety requirements of IEC 61511. Safety audits revealed that several safety instrumented systems (SIS) lacked the redundancy to achieve the required Safety Integrity Level (SIL 2).

The Jemmatech Solution:

SIL Assessment

• Risk analysis to identify critical safety loops requiring improvement.

System Redesign

• Replacement of individual transmitters with dual-redundant sensors feeding separate logic solvers.
• Introduction of multi-technology redundancy (use of different sensor technologies for the same measurement) to reduce the risk of common causes of failure.

Lifecycle Documentation

• Implementation of rigorous testing procedures and documentation practices to comply with audits and ensure ongoing compliance.

Result:

• Full compliance with IEC 61511 achieved.
• Increased confidence in plant safety for operators and stakeholders.

The future: Digital tools meet practical engineering

Digital transformation is changing the way we tackle engineering and IT challenges. Digital twins enable engineers to simulate changes without physical disruption. AI-powered analytics can detect anomalies before they lead to failures. While tools evolve, the core principles remain: listening to customers, understanding the real environment, and developing powerful solutions.

At Jemmatech, we combine cutting-edge technology with practical, field-proven experience to deliver solutions that ensure industrial business continuity safely and cost-effectively.

Frequently Ask Questions

Question 1: What are electrical and instrumentation systems in industry?

Electrical systems distribute and manage energy in industrial facilities, while instrumentation systems measure and control key process parameters such as temperature, pressure, and flow. Together, they ensure safe, reliable, and efficient operation.

Question 2: Why is power quality important for industrial processes?

Poor power quality, such as voltage dips, harmonics, or transient overvoltages, can damage sensitive equipment, cause data errors in instrumentation systems, and lead to costly production shutdowns. Engineering solutions help minimize these risks and ensure process stability.

Question 3: How do engineers manage signal interference in harsh industrial environments?

Engineers use shielded cables, fiber optics, proper cable routing, and grounding techniques to protect signals from electromagnetic interference (EMI) and physical damage in demanding environments such as oil rigs, chemical plants, and mines.

Question 4: Can legacy systems be integrated with modern digital platforms?

Yes! Engineers often use protocol converters, retrofit legacy equipment with smart technologies, and gradually migrate systems as part of planned maintenance to integrate legacy systems with modern digital infrastructures without major disruption.

Question 5: What is functional safety, and why is it important?

Functional safety involves designing systems that prevent dangerous failures in industrial processes. Standards such as IEC 61511 require rigorous assessment and development to reduce risks to people, the environment, and equipment.

Question 6: What impact does digital transformation have on electrical and instrumentation solutions?

Digital tools such as digital twins, AI analytics, and predictive maintenance help engineers simulate scenarios, diagnose problems faster, and optimize processes. This results in increased reliability and cost savings for industrial electrical and IT systems.
