I currently have some professional sound equipment connected to a power/surge protector that, when initially connected, indicated a 120 volt connection. Now, for unknown reasons, the power/surge protector is flashing, indicating a change in voltage has occurred, and when a voltage meter was used to check the line, it indicated that a voltage of approximately 132 volts is now present. What could have happened, given that nothing has been changed, and what do I do to correct the problem?

You may have something else on the circuit that is drawing power - freezer, heat, water heater etc. When they come on your voltage drops to 120 and when they cycle off it jumps to 132.
Try another circuit.
Other possible causes are your house main box is overloaded or your power company is not able to keep up with demand.

Line voltage fluctuations are common in most power grids. Utilities deliver within a range of 108v to 135v commonly. If you've got large commercial or industrial users in your sector of the grid their usage cycle can affect your voltage. The best way to protect ALL of the sensitive electronics in your building is to install both a surge arrestor AND and surge capacitor on your service panel. You can get them at a local electrical supply house like Graybar or call an electrician. Modular portable surge arrestors/suppressors that you plug into are not the best protection. I know because I used to be a sales rep for manufacturers of the suppressors. Suppressors only block sharp spikes. The panel mounted surge capacitor will even out the voltage fluctuations. Well worth the investment.

You should call y our power company and tell them that your voltage is wrong.
