Protection devices, quenching effects of lightning, a surge voltage limiter, or discharger (OPS). OPS are compact and are installed in the shield, like other machines, fuses. OPS are the first stage protection and are connected to the input voltage in place of the house. But can be devastating not only a sharp jump in current, and voltage that exceeds the norm. For example, the voltage at 250-260 volts is too high, and 190 and below - undervalued.
Especially dangerous is the power for refrigerators and office equipment. Since the voltage drops in these limits to cope voltage regulator that supports it within the normal range - 220 volts. But if the voltages beyond the 190-250 B? In this case, not everyone copes stabilizer and this regime is for him an overload that threatens to damage it. Some regulators are equipped with protection function to disable it in an emergency situations. You can use and complete solution by installing an additional module that will control the voltage. Voltage relay switches off the load when the network parameters are beyond the norm, if stabilizer can not cope with the emergency high or low voltage. When you return the network settings to normal, the voltage is applied again in the house reappears electricity. Such a system, the relay voltage regulator voltage, set in one apartment, rescued from 275 volt appliances.
Everything happened very clearly, when a 255 volt relay power outages in the apartment, while returning the voltage to 250 and hold it for three minutes, the light turned on, thus equipment working in the comfort mode, while the high voltage cut off. Caused by local electrician made sure that the house too high voltage is applied, and went to take action. This system has one drawback: at the moments when the stress of emergency in the house there is no light protection tripped. By adding an uninterruptible power supply can be an ideal protection for your home from overcurrent, overvoltage and Error electricians.
