Research On The Selection And Installation Points Of Surge Protector

The voltage protection level Up of the surge protective device device should always be less than the impulse withstand voltage Uchoc of the protected equipment and greater than the maximum operating grid voltage Usmax derived from the grounding type, i.e., UsmaxUpUchoc. If the line is unshielded, the line induced voltage should also be taken into account, and Uchoc should be considered at 80% of its value.

The leads between the surge protector device and the protected equipment should be as short as possible, within 0.5m.

Other names for surge protection device:

Power supply protector: AC power supply protector, DC power supply protector, switching power supply protector, etc.

Signal protector: Low-frequency signal protector, high-frequency signal protector, antenna feeder protector, etc.
