50hz analysis for proper equipment

Although the use of 400-Hz power is certainly declining, especially in mainframe computer power systems, some existing systems may need upgrading because of additional equipment or retrofitting. As such, it's important that you understand the restrictions associated with this frequency.

    In fact, the accuracy of the clock DEPENDS on the accuracy of the mains power line frequency. A 60Hz clock operated at 50Hz will lose 10 minutes per hour! That doesn’t make for a very useful clock. The converse is also true. A 50Hz clock (say, from England) operating on 60Hz mains power line will run 12 minutes fast per hour.

    50 Hz vs. 60 Hz IN OPERATING SPEED. The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is simply that 60 Hz is 20% higher in frequency. For a generator or induction motor pump (in simple terms) it means 1,500/3,000 RPM or 1,800/3,600 RPM (for 60 Hz). The lower the frequency, the lower will be the iron losses and eddy current losses.

    There are two reasons you may have trouble. 50Hz into 60Hz-designed inductors can always be a problem, depending on how conservatively the original 60Hz design was with respect to saturation. If saturation is more than 20% away at 60Hz, then you'll get away with it at 50Hz. If closer, then the core could saturate, drawing many times more current.

    Oct 27, 2017 · Any transformer supplied for use at either frequency will be designed for 50Hz. Many 60Hz transformers will survive fine on 50Hz provided the voltage is at the low end of the intended voltage range. 50Hz induction motors and vibratory devices will run fast and may lack power on 60Hz, while 60Hz versions will run slow and develop more heat on 50Hz.
