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.
Identifying the Root Cause of Motor Failure
As motors become increasingly sophisticated, the potential for failure due to a combination of mechanical and electrical factors grows. Understanding the root cause of motor failures is essential to minimize costly downtime and ensure long-term reliability.
Solutions to Common VFD Faults
Solutions to Common VFD Faults Key Takeaways Variable Frequency Drives (VFDs) are highly susceptible to environmental conditions. Regular maintenance is key to VFD longevity. Maintenance and voltage/current protection are keys to ensuring mean time between failures of the drives. If not correctly addressed, these issues lead to downtime, equipment misoperation, or failure of the VFD […]
Power Quality Monitoring Devices: Recording Transient Voltage
Power Quality Monitoring Devices: Recording Transient Voltage Key Takeaways Power quality monitoring (PQM) devices are not uniformly regulated in how they measure power quality events. The intrinsic properties of transient voltage are unlike other power quality events, meaning PQM devices capturing other power quality events (i.e. voltage sags, voltage swells, or voltage interruptions) are not […]
Concerns with Common Mode SPD Application
Concerns with Common Mode SPD Application Key Takeaways Common mode (phase-to-ground mode and neutral-to-ground mode) suppression can create unwanted performance outcomes for end users. Common mode suppression can create touch safety hazards. Metal oxide varistors (MOVs) are surge protective device (SPD) components designed to absorb transient overvoltage and dissipate energy as heat. Introduction An electrical […]
Integrated vs. Externally Mounted Surge Protective Devices
Integrated vs Externally Mounted Surge Protective Devices Key Takeaways Integrated surge protective devices (SPDs) create limitations when sourcing parts or replacements that non-integrated SPDs do not. Integrated SPDs can damage the electrical distribution system during failure conditions; non-integrated SPDs cannot. Externally mounted SPDs offer serviceability without the need to de-energize the entire load center; integrated […]
Common Misconceptions About SPDs Nominal Discharge Current Ratings: Part Two
Common Misconceptions About Surge Protective Devices Nominal Discharge Current Ratings: Part Two Key Takeaways The existing single-pulse In test is inadequate to assess robustness or safety. Increasing the kA of a single-pulse test will not give an accurate representation of MOV-type surge protective device (SPD) responses to multi-pulse lightning flashes. Service entrances where ANSI/UL 1449 […]
Common Misconceptions About SPDs Part One: Nominal Discharge Current Ratings
Common Misconceptions About Surge Protective Devices Part One: Nominal Discharge Current Ratings Key Takeaways Nominal Discharge Current Rating (In) tests are not based on normal operating conditions. In ratings are not indicative of surge protective device (SPD) safety nor robustness. The vast majority of SPD failures occur due to temporary overvoltage (TOV) conditions, which the […]
Modern ATS Components Are Highly Susceptible To Failure Caused By Transient Voltage
Modern ATS Components Are Highly Susceptible To Failure Caused By Transient Voltage Key Takeaways Transient voltage is inherent to AC power systems. Modern automatic transfer switches (ATSs) contain sensitive components that are highly susceptible to damage caused by transient voltage. Voltage monitoring control boards and control power supplies commonly fail due to damage caused by […]
