Equipment commissioning in Finland

May 31, our company technical team completed the works under the contract on production, delivery and commissioning of a CMM-4/7 unit in Finland (Helsinki).

This equipment is designed for businesses that repair and install high-voltage oil-filled equipment. The first transformer it services was a 400 MVA  transformer.

Operating modes of the unit

CMM-4/7 operates in three modes. Each  mode performs a certain set of functions:

  • “Degassing mode” consists of an automatic warm-up of the unit; heating oil to a set temperature, filtration and degassing ;
  • “Heating and filtration” consists of heating and filtration of oil without degassing in a vacuum column
  • “Manual mode” involves a diagnosis of good condition of units components, i.e.  valves, pumps, etc.

CMM-4/7 processing rate

The unit can treat any transformer oil with viscosity below 70 cSt at 50 ° C. The processing rate in degassing mode, is 4 m3 / h, and in heating and filtration mode  is 7 m3 / h.

Processed oil parameters:

  • Volumetric gas content – below 0.1%;
  • Moisture content by weight – below 10 g / t;
  • ISO 4406 industrial purity class   – / 14/12;
  • Mechanical impurities content – below 8 g / t;
  • Filtration fineness is 5 μm.

Additional Features

TSS (Transformer Security System). is provided to monitor the oil level in a transformer.   It protects a transformer from oil leaks or breaking of hoses.
