System and supplying transformer information

Please provide basic information of the electrical system and the supplying transformer. Please do not use thousand separators.

Downstream line-to-line voltage (V):

Please contact sales@meruspower.fi for solutions at higher voltage levels.

Frequency (Hz):

Transformer rated power (kVA): Short circuit impedance (6.5 % by default) (%):

4W or 3W connection:

Systems where neutral wire exists can be selected as 4W. 4W connection is needed only when neutral wire currents (harmonics 3rd, 9th, 15th …) need to be compensated (3W by default).

4W 3W

Compensation

Please select the desired compensation level:

Compensation of all harmonics Meeting IEEE-519 1992 requirements Meeting IEEE-519 2014 requirements Meeting IEEE-519 2022 requirements

Meeting EN 50160 requirements Meeting ER G5/4 planning requirements Meeting AS/NZS 61000.3.6 2012 requirements Custom
