What You’ll Learn

Focused, practical modules that help you evaluate risk, make reliability-focused decisions, and operate critical systems with more confidence.

Electricity Fundamentals Build the electrical base for understanding critical power systems. +

Build the electrical foundation you need to understand every system in this course — voltage, current, power, three-phase distribution, and how power flows from utility to load.

Power Quality Recognize power events and anticipate their operational impact. +

Learn to identify, categorize, and respond to power quality events — transients, sags, swells, brownouts, and outages — so you can anticipate their impact and plan accordingly.

Emergency Generators Evaluate backup power protection against sustained outages. +

Understand how standby generators are specified, sized, and integrated into a facility’s electrical design so you can evaluate whether a site is properly protected against sustained outages.

Automatic Transfer Switches Follow transfer sequences and troubleshoot the handoff to backup power. +

Master the full ATS sequence of operations — from utility loss detection through generator start, load transfer, retransfer, and cooldown — and learn to configure, maintain, and troubleshoot these systems.

UPS Systems Protect critical loads and plan maintenance without exposing the load. +

Understand how double-conversion UPS systems protect critical loads, recognize common failure modes, and evaluate maintenance choices that avoid exposing the load.

Static Transfer Switches & PDUs Understand last-line power transfer and downstream distribution. +

Learn how STSs provide the last line of defense for critical loads, how to perform safe maintenance bypass using key interlocks, and how PDUs distribute power downstream.

Cooling Identify airflow, redundancy, and heat-removal risks before uptime suffers. +

Trace the full heat-removal path from CPU to cooling tower, evaluate airflow and redundancy, and identify cooling risks before they become uptime problems.

Fire Protection Balance life safety with protection of mission-critical infrastructure. +

Understand fire protection objectives, how VESDA early smoke detection works, and how to balance life safety requirements with the protection of mission-critical infrastructure.

Commissioning Validate systems early so facilities function as intended at handover. +

Learn how to run a commissioning program that starts early, catches problems before they become expensive, and produces a validated, fully functional facility at handover.

Monitoring & Controls Use alarms, trends, and controls data to see issues clearly. +

Understand BMS and EPMS architecture, interpret alarms and trends, and use controls data to distinguish routine conditions from issues that require action.

Incident Management Respond to outages with structure, speed, and better communication. +

Develop a structured response to outages focused on safety, speed, communication, and reducing the likelihood of repeat incidents.

Maintenance Management Build preventive programs that reduce unplanned failures. +

Build a proactive preventive maintenance program with a structured equipment list, schedules, and procedures that keep critical systems reliable and reduce unplanned failures.

Capacity Management Spot capacity risk across power, cooling, network, and space. +

Track power, cooling, network, and space resources against actual load so you can spot capacity risk before redundancy or derating exposes a weakness.

Energy Efficiency Reduce consumption without compromising reliability. +

Identify practical opportunities to reduce energy consumption — from variable frequency drives and retro-commissioning to high-voltage distribution strategies — without compromising reliability.

★★★★★

“Brilliant course! I still remember the very first course I took with Dan while preparing for my PE exam — the support he provided made a huge difference and helped me pass with confidence. A few months later I came across the Critical Systems Engineering course, and once again it exceeded expectations. It offers a truly holistic view of system design, maintenance, and best practices, with a clear way to understand the engineering behind complex systems. With the same level of professionalism, clarity, and dedication, Dan delivered yet another masterpiece. Truly appreciated.”

Frequently Asked Questions

Is this course accepted for PDH credit in my state?

In most states, yes. This course meets continuing education standards for licensed PEs and includes a certificate of completion. Most states accept self-directed learning if it’s relevant and well-documented. A few states (NY, FL, NC, LA, IN, NJ) have more specific requirements — check with your board if you’re licensed in one of them.

How many PDH hours will I earn?

12 PDH hours upon successful completion of the course and final exam.

Is there a test I need to pass?

Yes. There’s a short quiz at the end of each section and a final exam at the end of the course. A 70% passing score is required to earn your certificate. You can review material and retake quizzes if needed.

Will I receive a certificate?

Yes. Once you complete the course and pass the final exam, you’ll receive a certificate confirming your 12 PDH credits.

Can I access this on mobile?

Yes. Watch on any device with internet access. Progress is tracked automatically.

Do I need a PE license to enroll?

No. The course is designed for licensed PEs seeking PDH credit, but anyone interested in critical systems engineering is welcome to enroll.
