DACPOL offers a wide range of surge protection devices. Surge protectors have various applications: for photovoltaic protection, for vision systems, for power line protection, for Fieldbus networks, for LED protection, for RF applications and for weighing systems. Our clients have known for many years that they can rely on the quality of our products. We constantly strive to make the ordering process from the semiconductors department as convenient as possible, which is why we allow orders to be placed via Internet and phone.
What is a surge protector?
A surge protector is a device designed to protect electrical equipment from overvoltage. The device limits the follow current. Overvoltages occur during lightning strikes into the power line or when switching on or off an unloaded overhead line. Overvoltages can lead to insulation damage or other component failures.
What are the main parameters of surge protectors?
- Impulse current Iimp – is a current with a 10/350 µs waveform, defined by the peak value and charge Q. Used to test type 1 surge protectors, corresponds to a lightning current
- Nominal discharge current In – is an impulse current with an 8/20 µs waveform. Used to test type 1 and type 2 surge protectors, corresponds to indirect lightning strike or switching overvoltages
- Maximum discharge current Imax – is the maximum 8/20 µs impulse current value that will not damage a type 2 surge protector
- Maximum continuous operating voltage Uc – the AC voltage value that can be permanently applied to the surge protector terminals
- Voltage protection level Up – parameter characterizing the operation of the surge protector, indicating the maximum voltage to which the overvoltage is limited
- Temporary overvoltage UT – the maximum overvoltage value which, if applied for a certain time, will not damage the surge protector
- Maximum back-up protection – the maximum fuse rating installed before the surge protector to protect against long-duration short-circuit currents.
What are the types and applications of surge protectors?
We distinguish the following types of surge protectors:
- Type 1 – protects against direct and nearby lightning strikes
- Type 2 – protects most equipment from switching overvoltages and overvoltages reduced by type 1 surge protectors
- Type 3 – protects especially sensitive/expensive electrical and electronic equipment
- Type 1+2 surge protector sets
Type 1 surge protectors are most often installed at the beginning of the installation, powered from a cable line or overhead network, e.g., in the main LV switchboard. Their task is to divert the lightning current, resulting from a direct lightning strike into the network, to the ground.
Hybrid type 1+2 surge protectors are installed before the meter, protecting it from potential overvoltages. These devices provide protection against atmospheric overvoltages caused by lightning strikes to objects near overhead lines, directly into the line, or at some distance from the surge protector installation.
Type 2 surge protectors protect the installation from potential overvoltage effects caused by atmospheric discharges or switching processes in the power network. Their task is to limit overvoltages resulting from the operation of protective devices. Used to protect motors, transformers, or welders.
Type 3 is used to protect audiovisual equipment or computers. Their purpose is to protect sensitive devices from overvoltages reduced at earlier protection stages. These devices are used when the impulse withstand capability of equipment is undefined or when the distance between the sensitive device and the last protection stage is several tens of meters.
