Final answer:
A good surge suppressor should have large inductance or capacitance to filter out high-frequency noise, a ground fault interrupter (GFI), and an isolation transformer to prevent shock. Components such as circuit breakers or fuses, along with a three-wire system, are also important for preventing thermal hazards and ensuring electrical safety.
Step-by-step explanation:
To protect a computer from power surges, a good surge suppressor should have certain features that enhance its effectiveness. Firstly, it should have a large inductance or capacitance to filter out high-frequency noise in AC power that can potentially damage computers. A surge suppressor with a large inductance is more effective in absorbing or blocking high-frequency spikes, while a large capacitance would help smooth out the noise.
Additionally, key protective features should include a ground fault interrupter (GFI), which prevents electric shock by rapidly cutting off power whenever it detects that the flow of current is taking an unintended path, such as through a person. An isolation transformer is also important as it provides galvanic isolation from the main power source, which can prevent not only shock but also reduce the transmission of noise and surges.
Moreover, effective surge protection may include components like circuit breakers or fuses, which shut off electrical power in cases of excessive current to prevent fire and thermal hazards. The use of a three-wire system that includes live/hot, neutral, and earth/ground wires, with the device's case and neutral wire being grounded, further enhances safety by preventing electric shock and thermal issues.
