It is important to keep in mind that solving harmonic problems requires combining measurements with analysis and system calculations. Measurements are used to map harmonic generation.<\/p>\n<p>It is usual to start measuring at the level where problems occur or where filters are to be installed. However, it is important to be aware that harmonics generated by rectifiers can be amplified due to the resonance between inductive and capacitive components in the network. In cases where shunt capacitors or filters are present, these should be taken into account when assessing harmonic generation in the network. In networks with single-phase loads, the current in the neutral conductor must be measured in addition to the phase currents.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row custom_padding_last_edited=&#8221;on|phone&#8221; _builder_version=&#8221;4.20.2&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;#f2f2f2&#8243; background_enable_image=&#8221;off&#8221; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; max_width=&#8221;1920px&#8221; custom_padding=&#8221;2%|5%|0.2%|5%|false|true&#8221; custom_padding_tablet=&#8221;13%||||false|true&#8221; custom_padding_phone=&#8221;26%||||false|true&#8221; box_shadow_style=&#8221;preset4&#8243; box_shadow_color=&#8221;#326403&#8243; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_divider color=&#8221;#90a955&#8243; _builder_version=&#8221;4.20.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_divider][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243; custom_padding_last_edited=&#8221;on|phone&#8221; _builder_version=&#8221;4.20.2&#8243; background_color=&#8221;#f2f2f2&#8243; background_enable_image=&#8221;off&#8221; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; max_width=&#8221;1920px&#8221; custom_padding=&#8221;2%|5%|0.2%|5%|false|true&#8221; custom_padding_tablet=&#8221;13%||||false|true&#8221; custom_padding_phone=&#8221;26%||||false|true&#8221; box_shadow_style=&#8221;preset4&#8243; box_shadow_color=&#8221;#326403&#8243; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.16&#8243; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; custom_padding__hover=&#8221;|||&#8221;][et_pb_text _builder_version=&#8221;4.20.2&#8243; text_font=&#8221;Montserrat|300|||||||&#8221; text_font_size=&#8221;16px&#8221; text_line_height=&#8221;1.8em&#8221; header_font=&#8221;||||||||&#8221; header_2_font=&#8221;Montserrat|500|||||||&#8221; header_2_font_size=&#8221;40px&#8221; header_2_line_height=&#8221;1.5em&#8221; header_3_font=&#8221;Montserrat|300||on|on||||&#8221; header_3_font_size=&#8221;16px&#8221; header_3_letter_spacing=&#8221;1px&#8221; header_3_line_height=&#8221;1.4em&#8221; max_width=&#8221;750px&#8221; custom_margin=&#8221;||-2px|||&#8221; custom_padding=&#8221;|||&#8221; header_2_font_size_tablet=&#8221;&#8221; header_2_font_size_phone=&#8221;30px&#8221; header_2_font_size_last_edited=&#8221;on|phone&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h3>Transients, voltage dips, high frequency disturbances<\/h3>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.20.2&#8243; text_font=&#8221;Montserrat|300|||||||&#8221; text_text_color=&#8221;#000000&#8243; link_font=&#8221;|600|||||||&#8221; link_text_color=&#8221;#b11f23&#8243; header_font=&#8221;||||||||&#8221; header_2_font=&#8221;Montserrat|300|||||||&#8221; header_2_text_color=&#8221;#212d3b&#8221; header_2_font_size=&#8221;40px&#8221; header_2_line_height=&#8221;1.5em&#8221; max_width=&#8221;600px&#8221; custom_margin=&#8221;|||&#8221; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; link_text_color__hover=&#8221;#202020&#8243; link_text_color__hover_enabled=&#8221;on|desktop&#8221;]Measurements are carried out in connection with device failures e.g. insulation faults in transformers, capacitors, cables, motors, flashover in electronic circuits or in case of protective trips of e.g. frequency converters and converters.<\/p>\n<p>The measurement procedure depends on the type of transients to be recorded.
