The pressure gage was pegged/stuck at 300psi. Previously under same conditions, i.e. clean filters, the pressure gage burst. This gage had a maximum of 60psi. On another occasion the 3/4" circulating lines that are about 2 feet below the pool water surface jettisoned water about 3 feet above the water surface for several seconds. Does anybody sell automatic (say 50 psi) pressure relief valves to prevent such dangerous operation? Can power disturbances-high voltage/frequency swings create such dangerous conditions? Being an electrical engineer I know that motor torque increases with increase with voltage and that motor speed increases with increase in frequency. These increases then can cause the pump to push more water through and if the water lines cannot handle the volume the result then could cause dangerous pressure to develop.

You must have some form of restriction in the outlet from the cartridge canister to cause such a pressure build up. Check that there is nothing floating around loose that could block the outlet. Are the outlet hoses flexible or rigid, sometimes the inner lining of a flexible hos can separate and block the hose. The idea that power frequency fluctuations would speed the motor up can be ruled out as if the frequency fluctuated enought to cause that to happen the Power Station Generators/transformers etc would all have tripped way before it could happen.

why my swimming pool water gets cloudy?

Your filter might not be working properly. Have you changed the sand or cartridge within the last 5 years? If not, this could be the problem.
You could also be getting an algae problem, in which case you should look into getting some algaecide into your water as soon as possible.
Have you recently dumped in a lot of chemicals? If so, it could be stirring up your water and making it seem cloudy. If it is still cloudy or hasn't improved in a day or two, then it's not from the burst of chemicals.
You can try a water clarifier. You can buy it in a liquid form (often called Clear Magic, Clear Blue, True Blue, etc) or a cube form. It's a coagulant, meaning it bonds to the junk making your water cloudy. After putting it on, leave your pump on for at least 8 hours. The junk should be settling at the bottom and you can use your pool vac or automatic cleaner to vacuum it up.
You should also bring a sample of your water in an old water bottle to your local pool store, they can test it for free and tell you if there is some sort of chemical imbalance in your pool.
