Oil Cooled Transformers

One of the products in AEI's repertoire are specialized oil-cooled transformers, the applications of which include smelting scrap iron, refinement of steel, etc. These transformers use transformer/insulation oil as a cooling/heat dissipation medium, and they boast a much higher rate of efficiency at an economical price as compared to their air-cooled counterparts. Our catalogue of oil cooled transformers includes furnace transformers, solar transformers, wind transformers, dual primary & secondary transformers, etc. all up to 2.5 MVA.

High Voltage Breakdown Tester

AEI manufactured quality high voltage breakdown testers apply a high voltage across a specimen of insulation under test through a high voltage transformer making them ideal for carrying out high voltage breakdown tests in any work environment. Due to the rich raw materials that we use to manufacture our products, our testing units are more than flexible enough to work like an absolute charm in all kinds of work spaces.

INPUT : 240 v, 1 ph, 50 hz
OUTPUT : 0 to 80 KV rating step-less variable with zerostart interlocking & audio-visual indication
CAPACITY : Standard rati is 100 m.a. Tripping current canbe select from the given taps (Standard taps are 25,50,75 & 100 m.a. In 100 m.a. Tester)
ACCURACY : +/- 3%
DUTY : Intermittent
TERMINATION : One and at earth potential and the other at H.T insulator
METERING :

  • 3 ½ digit, calibrated digital K.V. meter reads the output s voltage with memory effect .
  • 3 ½ digit, digital M.A. meter to reads the leakage current.

PROTECTION :
  • MCB for protection against short circuit.
  • Instantaneous tripping circuit, having fast acting D.C. relays for positive de-energization of main power contactor to isolate the circuit if L.T. current exceed the rated current or H.T. current exceed the set current.
  • Protective resistance in H.V. side. The unit consists of two sub units viz.
    • Oil cooled transformer with first filling of oil
    • Desk type control panel or table top model panel
    • Interconnecting cable upto 3 meter length
