What should I do?” open=”on” _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n
Switch off the transformer as soon as possible and call in a qualified organisation to analyse the noise in the transformer and carry out tests.<\/p>\n

Possible causes:<\/p>\n
– Low oil level;
– No vacuum;
– Presence of gases inside the transformer due to possible partial discharges or C.C.<\/p>\n

It is advisable to carry out maintenance on any piece of equipment, from cleaning to retightening and electrical testing, in order to guarantee:<\/p>\n
– That the transformer is in compliance;
– Early detection of possible problems such as oil leaks, hot spots (pins or wiring), state of condition (insulation resistance).<\/p>\n

– Oil spill;
– Electrical discharge.<\/p>\n

Yes, if it’s significant, it requires rapid intervention.<\/p>\n

This means that the transformer will have to come into the workshop and generally undergo electrical entry tests, descaling, a drying process, replacement of the insulating oil with new oil, replacement of all the seals, final tests and painting.<\/p>\n

It is advisable to carry out maintenance on any piece of equipment, from cleaning to retightening and electrical testing, in order to guarantee:<\/p>\n
– Conformity of the motor\/generator;
– Early detection of possible problems such as hot spots (pins, wiring or winding), broken components, condition of the motor\/generator insulation resistance.<\/p>\n
