1) Step-up transformer power – nominal power capacity of Step-Up Transformer (for reference only).

2) Max U tap of SU Trans-r – max tap voltage in SU Transformer (for reference only).

3) Nom. U SUT – nominal input (primary) voltage of SU Transformer (380 V, 480 V, 500 V).

4) Nom. U / F of power supply – nominal parameters of power supply system (voltage / frequency).

5) Cable length / cross section – nominal parameters of cable line (length / cross section).

6) Max oper. Fmax operating frequency which is used in SUT tap voltage calculation. (It is recommended to run ESP system exactly at this frequency).

7) Max oper. Umax operating voltage at Freq. Converter when running at Max oper. Frequency (it is recommended to use value 320 V for stable operation of ESP system in case of input voltage drops).

8) Current limit – actual value of current limit preset in Freq. Controller for the given motor power capacity.

9) Desired current lim.: 150% – min recommended current limit in Frequency Converter.

10) Required tap voltage U in Step-Up Transformer – recommended tap voltage in Step-Up Transformer which was calculated with all losses in ESP system.

11) Tap voltage in Step-Up Transformer – selected actual tap voltage in Step-Up Transformer (it is recommended to choose the tap which is the nearest to recommended).
