TRANSFORMER OIL (BDV) TEST SET
Make: Clear Flow Corporation
Motorized Oil Testing Transformer: Oil testing transformer is equipment designed to test dielectric strength of Insulating oils as per reference standard IS 6792/1992 or IEC 156. Specification: Model: Motorized with auto manual switch. Input: 230V/ 240V, single phase, 50 C/s AC. Output: 0- 100 KV center tap earthed. Indication: Mains ON & HT ON lamps. Metering: Digital or Analog Voltmeter duly marked in KV. Protection: Electronic, fast action over current tripping device sensing HT current.
|Input Voltage||230V A.C.|
Transformer oil serves mainly two purposes one it is liquid insulation in electrical power transformer and two it dissipates heat of the transformer, acts as coolant. In addition to these, this oil serves two purposes, it helps to preserve the core and winding as theses are fully immersed inside oil and another important purpose of this oil is, it prevents direct contact of atmospheric oxygen with cellulose compromised due to aging / contamination; it leads to catastrophic event due to insulation flashover. The voltage withstands capability of oil often reduced due to contamination. The contamination can be due to dirt, water ingress and particulate cellulosic fibers.
