Oil BDV Test Set (Motorized & Manually Operated)

In all H.T. Transformers and Circuit Breakers etc. transformer oil or other insulant is a very important ingredient.
The liquid insulant used should have a very high dielectric strength. To test the dielectric strength of the INSULANT,
a very high voltage is passed through it. The failure of the dielectric strength of INSULANT is shown by a spark across
two electrodes. The apparatus to carry out this test is manufactured by us in various voltage ranges and models,
as per IS:6792/1972 and IEC-156, known as SAKOVA OIL TEST SET.


Oil Test Set

FEATURES:

The set comprises of the following parts viz. Control Panel, H.T. Transformer and Oil Test Cell (with electrodes & Gauge), housed in a sheet-metal cabinet, having an acrylic covered housing for Oil Test Cell.


CONTROL PANEL:

  • Continuously variable auto-transformer (variac) for smooth variation of output voltage, operated manually or by a constant speed synchronous motor, as desired.
  • “MAINS” & “H.T.” “ON & OFF” Switches, incorporating automatic tripping mechanism for protecting the H.T. Transformer against overloading.
  • Voltmeter to monitor output voltage, calibrated in Kilovolts.
  • Zero Start interlocking device, so that the set will not be energized unless the variac is brought back to zero output position.
  • Two pilot lamps, green and red for “MAINS ON” and “HT ON” indications.
  • Fuse for the L.T. side, one 3-Pin plug with 1.5 meter long cable for mains connection.

    • Oil Test Set

    H.T. TRANSFORMER:

    H.T. Transformer is RESIN CAST or OIL COOLED and of compact type, properly designed and treated for perfect tropicalization.


    TEST CELL:

    Test Cell is made of synthetic polymer and is mechanically tough, transparent and non-absorbent. The cell is complete with adjustable gap electrode arrangement and gauge, as per IS:6792/1972.


    SHOCK PROTECTION:

    The above equipment is wired and housed in a highly finished sheet-metal cabinet. A hinged perspex cover is provided in the unit for covering the H.T. Terminals, with suitable interlocking device. The set will not be energized unless the cover is closed.
