Voltage surges are undesirable in electrical systems. The question does not make sense and/or has insufficient information to be answered.
The best surge protector for a refrigerator is one that is specifically designed for appliances with high power needs, such as refrigerators. Look for a surge protector with a high joule rating and voltage protection to ensure the safety of your refrigerator during power surges.
A surge suppressor or protector is used to protect electronic devices in case of voltage spikes. A surge protector works by limiting the amount of voltage supplied to the plugged in electronic devices by blocking or shorting to ground any voltage above the safe threshold.
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
Surge voltage means sudden big voltage. Surge voltage is of two types lightening surge and switching surge or in electrical engineering, a voltage rise that endangers the insulation of electric equipment. A correct calculation of voltage surges is of great economic and practical importance in the selection of insulation and of measures for power supply system protection, particularly for voltages above 10kilo-volts(kV). There are two types of voltage surges lightning surges and system generated surges.
A sudden and dramatic increase in voltage typically caused by lightning is known as a power surge. Power surges can damage electrical equipment and appliances if they are not properly protected by surge protectors or other safeguards.
A surge is an over voltage and over current situation and a brownout is an under voltage situation.
The maximum amount of voltage that a surge protector will allow through itself before it will suppress the power surge. When the device reaches its clamping voltage, it blocks any further current from flowing through the device and into a computer system or other electronic device.

The line voltage increased over 110% of it's normal level is known as Surge , Whereas the surge monitor is a device which is used to measure the voltage increase than the normal value.
A refrigerator surge protector helps protect your appliance from power surges by regulating the electrical flow, preventing damage to the refrigerator's sensitive components. This can extend the lifespan of your refrigerator and save you money on repairs or replacements.
A surge limiter (or surge suppressor) can be installed into your electrical panel to help protect your home from dangerous electrical spikes. It is usually installed in conjunction with a lighting arrestor. You can also buy single use surge protectors for sensitive appliances, such as computers, tv's, and stereo systems.
