25KA Type 1 Surge Protector Application:
• Prevents lightning overvoltage and transient overcurrent from intruding into the power supply line from disrupting the normal operation of the power supply system and electrical equipment.
• It is applicable to lightning protection for the power system in areas with high lightning risk (LPZ0B or the interface between LPZ0B and LPZ1).
• Suitable for three-phase TN-C power supply system with AC of 50 to 60Hz
• Generally installed in the building into the low-voltage main distribution cabinet or low-voltage main switch.
Open-Circuit Failure in SPDs
Open-circuit failure is a common mode of failure in SPDs, particularly those with varistors. This type of failure typically occurs due to the natural ageing process or thermal protection mechanisms. When an SPD reaches the end of its life, an internal disconnector is activated, rendering the SPD inoperative. This disconnector is designed to disable the SPD to prevent further damage.
In SPDs with gas discharge tubes, internal disconnectors (thermal protection) may also be used to protect against abnormal overheating caused by unexpected follow currents or surge currents. It’s important to note that thermal runaway, a common cause of failure in varistor-based SPDs, does not apply to SPDs with gas discharge tubes or encapsulated spark gaps.
A spark gap, another type of SPD, may fail in an open-circuit mode when it can no longer ignite an arc due to electrode wear or a faded electronic ignition circuit. In this state, the SPD becomes permanently open, leaving the system unprotected.
SPD and lightning protection
Surge protection refers to the protection of systems and electrical devices against excessively high voltage peaks caused by switching operations and lightning strikes.
Home today contain an average of $15,000 worth of electronic equipment not protected from voltage surges. BRITEC SPD is specially designed to help protect home appliances from over-voltages induced by lightning current. Complete solution to cover single phase and three phase installations.
