Minnesota’s school districts operate modern technology-rich facilities through extreme temperature swings and ice storms that challenge building electrical systems year-round.
K-12 schools generate thousands of transient voltage events daily from their own infrastructure — HVAC systems cycling between classrooms, elevator motors, kitchen equipment, and lighting ballasts switching. 80% of damaging transients originate inside the building, not from the utility. Standard surge protectors stop the big spikes but do nothing about the high-frequency noise that degrades security systems, network infrastructure, and classroom technology over time.
School security systems, fire alarms, and emergency communications depend on clean, reliable power. Transient voltage events can cause false alarms, system resets, and gaps in coverage.
Access control, surveillance cameras, fire alarms, and emergency communication systems are mission-critical in school environments. Transients cause false alarms, system lockups, and gaps in security coverage that put students and staff at risk.
Switches, access points, servers, and district-wide network equipment are both essential and sensitive. Transients cause connectivity drops, data corruption, and accelerated hardware failure — disrupting instruction and administrative operations.
Interactive displays, projectors, Chromebook charging stations, and audiovisual equipment in every classroom multiply the impact of power quality problems. A single transient event can take an entire wing of classrooms offline.
Variable frequency drives, building automation controllers, and energy management systems are among the largest sources of transients — and among the most vulnerable. Failed HVAC means cancelled classes and uncomfortable learning environments.
These are documented outcomes from educational facilities that installed TPS power conditioning and surge protection.
Minnesota’s school districts — Minneapolis Public Schools, St. Paul Public Schools, Anoka-Hennepin, Osseo, Rochester, and Duluth — operate technology-rich facilities through some of the most extreme weather in the continental U.S. Ice storms, severe thunderstorms, and temperature swings from -30°F to 100°F stress electrical systems year-round. These districts depend on reliable power for 1:1 device programs, security systems, and modern HVAC.
