Understand transient voltage through real-world application.
Surge Protection Industry Terminology Explained
SPD. TVSS. I(n). kA. MCOV. VPR. SCCR. The surge protection industry is a virtual swamp of alphabet soup.
Most SPD specifications describe device capability under controlled conditions. Very few describe system behavior. Effective surge protection is determined by how the device interacts with the electrical system, not how it performs in isolation.
Below we’ve compiled the definitions to these (and more) to help electricians, maintenance personnel, and engineers wade through industry jargon.

Surge Protector Manufacturer | Maxivolt
Maxivolt is an American surge protector manufacturer that produces custom and standard industrial and commercial solutions to protect against transient voltage.
Why Power Outages Cause Equipment Failure — And How to Prevent It
Power outages don’t just interrupt operations — they can trigger transient overvoltage events that damage and/or destroy equipment, and cause equipment malfunctions. Understanding why this happens and how to prevent it is critical for reliability, uptime, and safeguarding sensitive assets.
Transient Voltage Threatens EV Charger Reliability
Transient voltage events—short, high-voltage spikes—pose a serious threat to EV charging systems. Left unaddressed, these disturbances can degrade, disrupt, or even destroy sensitive components in both chargers and connected vehicles.
Diagnosing “Ghost Faults”
Ghost faults—also sometimes called phantom or elusive faults—are intermittent electrical anomalies that cause unexpected and unwanted behavior in equipment (e.g. nuisance trips, resets, flickers).
3 Must-Haves for Power Quality
Protect equipment and reduce downtime with three power quality essentials: transient voltage mitigation, harmonic control, and proper grounding. Learn how a layered approach improves reliability, efficiency, and asset life.
Transformers Do Not Stop Transient Voltage
Transformers are a staple in electrical systems, stepping voltage up or down as needed. But when it comes to one of the most prevalent power quality threats—transient overvoltage—transformers fall short. Here’s why that matters more than one might think.
Common Pump-Off Controller Failure Modes and Their Fixes
Like all automation technologies, POCs are not without their challenges. Despite their advanced capabilities, they can become sources of inefficiency or downtime if not properly configured, hardened, and maintained. Understanding the common failure modes associated with POCs is essential for technicians tasked with ensuring reliable and optimized pump operation.

How Transient Overvoltage Affects Microprocessor Logic
Transient overvoltage events—such as lightning, switching surges, or electrostatic discharge (ESD)—introduce brief but disruptive voltage spikes into microprocessors. These transient overvoltages induce logic faults that manifest as unexpected malfunctions or system errors.
How to Reduce Electrical Failure In Mini-split Units
While mini-split systems, also known as ductless systems, are hailed for their flexibility and energy efficiency, they are prone to electrical issues.
Persistent Equipment Failures Despite SPD Usage: Unveiling Potential Causes
SPDs are essential components in safeguarding electrical systems from damaging voltage spikes and surges. However, their effectiveness can be compromised by a variety of factors, including oversizing, improper grounding, and insufficient protection. Moreover, issues such as TOV, voltage sags, spikes, harmonics, and frequency variations present additional risks that must be addressed through a comprehensive approach to power quality management.
Best Practices: Extending the Life of Lithium-Ion Batteries
Optimizing lithium-ion battery lifespan requires understanding how environmental conditions, SoC management, charging/discharging rates, and current exposure impact battery health. With careful handling and modern technology such as BMS, controlled charging infrastructure, and surge protection, users can significantly extend the lifespan of these essential power sources, ultimately reducing environmental impact and lowering costs over time.
Decades of Experience & Knowledge Protecting Industries from Transient Voltage
Product selection, placement, and installation are critical to the performance of a surge protection system. Maxivolt determines what devices are needed based on the immunity level of the specific electrical load to be protected. The placement of the devices is then determined based on the ideal location to maximize protection against both externally and internally generated power surges. Next the device must be installed as “the path of least resistance” in the system. Coordination of these 3 critical factors ensures the client’s surge protection system will perform to it’s optimum capabilities.
