Maxivolt Services
Maxivolt is a trusted supplier and integrator of surge protection devices that deliver American-made power protection supported by decades of engineering, training, and on-site experience. Our team goes beyond providing a reliable surge protective device and offers additional training programs, on-site assessments, and client by client-by-client-based strategies that optimize protection while staying within budgets or timelines. Browse our additional services below that include Transient Voltage 101 education, to complete facility evaluations to identify problem areas or conditions that may keep your business from operating at full capacity.
Transient Voltage 101
Studies show that transient overvoltage is now the 3rd leading cause of unplanned shutdowns. This interactive training session educates teams on the causes, vulnerabilities, and mitigation of transient overvoltage. Properly mitigating these events provide users with difference-making improvements in equipment reliability and lifespan.
IEEE-Approved Transient Voltage Course
Despite advancements in our understanding of transient overvoltage and its mitigation, outdated assumptions still influence many design decisions, potentially leading to system vulnerabilities and equipment failures. This engaging and informative training is designed to challenge misconceptions, provide clarity on transient overvoltage standards, and empower participants with actionable insights for designing robust and resilient systems.
Transient Voltage Mitigation Assessment
During an on-site assessment, Maxivolt professionals comb through a facility’s electrical system to identify transient overvoltage vulnerabilities. This helps our team create a custom mitigation and application strategy for our client’s facility. All on-site assessments include our Transient Overvoltage Mitigation Training, and Installation, Operation & Maintenance Training.
