Frequency Change

Well, it rather depends on what the circuit consists of, which cannot be seen from here. If it were a synchronous clock, for example, it would run at 60/50 times its design speed, and only show the correct time about twice per day.

About twice per day? You mean there's a chance it could be correct three times per day?

How would you ever know that it was correct.

Motors: Changing between a 50 and 60Hz supply. - Electric motors ...

the effect of changing the frequency is also the cycle of all eletrical equipment, thats why today we have all king of equipment that have a auto HZ frequency, this application is to protect our appliances<

Ego clash between US and UK engineers .

One of the answers is given by Mr. PWSlack GURU.

I will try to explain some other affects.

Well known Voltage equation for AC equipment based on Induction principle is

1. For Transformer: V=4.44xAxBxFxN----------1(for Transformers & Induction Motor)

Where: V= Volts; A= Area of magnetic circuit in M2; B=Flux density Web/M2; N= number of turns F= design frequency & F_N applied new frequency.

For transformer: V=4.44*A*(B*F_N /F)*F*N; Therefore; Iron losses will decreases

2. For Induction Motors (Pumps & Fans): Speed N= F/p

Where: N =Speed of the motor; F= Design frequency; p=pair of poles; F_N =applied frequency

N_N =F_N*(N/F); Speed increases so the effects are

1. Volume Flow (Q=M³/s) varies as: Q_N = (N_N / N)*Q; So Flow increases

Head (H=Meter) developed varies as: H_N = H*(N_N/N)²; So Head increases

Power (P) absorbed varies as: P_N = P* (N_N /N)³; So Power increases

Similarly follows Fan motor.

3. For impedance of cable or wire:

Inductive (L) impedance per unit length: Z = R+J 2πF* L; impedance value increases

Capacitive(C) impedance per unit length: Z = R+1/ (J2πF*C); impedance value decreases

Where: Z, R, L & C are Impedance, Resistance, Inductance & Capacitance respectively:

4. In Long Transmission Line: Wavelength, velocity of propagation of wave and frequency are λ, ν and F respectively.

Velocity of wave propagation given as: ν = F* λ miles per second. The typical values for 60Hz are as follows:

V= 182,580 miles/second

λ= 3043 miles; Velocity of propagation of wave increases
