Question: The influence of voltage on the refrigerator
Answer: … If the voltage is lower than 187 V, the refrigerator can’t work on and even burn down the compressor. If the voltage is higher than 242 V, the compressor and other electric parts are easy to be burnt out.
How does an on delay timer work? With ON-delay operation, the Timer receives an input and then an output signal is output by switching the Timer contacts after a set time delay. This name is used because there is a delay between when the input signal is received (i.e., turns ON) and when the output signal is output.

Do rolling blackouts cause power surges? Today, rolling blackouts present another source of harmful surges. Surges can be created when a disconnected electrical load is reconnected. For example, when the utility recovers from an outage and power is reintroduced to a building, a very fast high-voltage pulse is induced.
What is the term brown out? A brownout is like a blackout, just not as bad. Where an electrical blackout means a loss of electricity, a brownout is a reduction in power.

How does on delay and off delay timer work? Operation of On Delay/True Off Delay Function
Upon application of input voltage, the time delay (t1) begins. At the end of the time delay (t1), the output is energized. When the input voltage is removed, the output remains energized for the time delay (t2). At the end of the time delay (t2), the output is de-energized.
How do you interpret on delay timer circuits?
