Electrical supply tolerance
Tension whilst the machine is functioning +/- 5% the standard tension.
Frequency
+/- 1% the standard frequency in a constant manner.
+/- 2% the standard frequency for a short amount of time.
Harmonic
Harmonic distortion for the sum of the harmonics from the second to the fifth not superior to
10% of the total tension. An extra distortion is allowed from the sixth to the thirtieth for an
amount of 25% on the total value between the tension conductors..
Unequal tension in the three phase
Neither the sequence component inverted and the component zero must be superior to 2
% of the direct tension sequence component.
Tension impulses
The impulses must not be superior to 1,5 ms with a time of up/down between 500 ns and 500
s, and a diving value not superior to 200% of the efficient value of the tension.
Tension interruption
The tension must not be interrupted and/or the tension must not go to zero for a time
superior to 3 ms, no matter the instant of the tension wave. Between the following two
interruptions a time superior to 1s must pass by.
Intervals in the tension
The intervals in the tension must not be superior to 20% of the diving tension for one cycle.
Between the following two interruptions a time superior to 1 s must pass by.
Responsibility
NOTE
3.2
Qualified operator
The installation of the machine must be carried out by qualified personnel, personnel
exclusively trained and authorised and following careful study of this manual.
