Electric surges are sudden voltage spikes that can damage electrical devices and disrupt operations. Using high-quality surge protection devices (SPDs) effectively prevents costly equipment failure. LEEYEE’s SPDs offer fast response times, high discharge capacity, and reliable protection for residential, industrial, and PV systems, meeting international safety standards such as TUV and CB certification.
Learn how to prevent electric surges from damaging your infrastructure with proven technical solutions.
Understanding Electric Surge and Why It Matters
An electric surge, also called a transient overvoltage, is a brief but intense spike in voltage within an electrical circuit. These spikes can originate from lightning strikes, power grid switching, or equipment faults. According to the IEEE Std C62.41.1™, over 80% of surges are generated internally within facilities, with external factors like lightning causing the most severe events.
In power distribution, even a surge lasting microseconds can push voltages thousands of volts above nominal levels. Without protection, this leads to insulation breakdown, electronic component failure, and fire hazards.
Why Surge Protection Devices (SPD) Are Critical
Surge Protection Devices (SPDs) act as a barrier against surges, diverting excess energy safely to the ground. The effectiveness of an SPD depends on critical parameters, such as:
-
Rated Voltage (Uc): The maximum continuous operating voltage, typically set at 275V~440V for low-voltage systems.
-
Nominal Discharge Current (In): 20kA-40kA ensures durability against common surges.
-
Maximum Discharge Current (Imax): Up to 80kA for severe lightning strikes.
-
Response Time: Less than 25 nanoseconds for instant protection.
LEEYEE’s SPD products offer high discharge capacity with advanced MOV (Metal Oxide Varistor) technology, ensuring fast response and stable performance. Their SPDs are widely used in power distribution systems, data centers, and photovoltaic solar installations.
Industry Applications for Electric Surge Protection
Electric surge protection is indispensable across industries:
-
Residential Buildings: Protect household appliances from grid instability.
-
Industrial Facilities: Safeguard machinery and automation controls.
-
PV Solar Systems: Prevent inverter damage caused by lightning.
-
Telecommunications: Ensure stable network operation in data centers.
-
EV Charging Stations: Mitigate voltage spikes in car charging infrastructures.
By integrating SPDs, companies improve operational safety, reduce maintenance costs, and extend equipment life cycles.
