SFRA Test (Sweep Frequency Response Analysis)
Doble Make SFRA Test Kit

The Purpose of SFRA Test is mainly to check any Mechanical Dislocation inside your transformer during Transportation or due to Fault Condition.

Frequency Sub-Band
< 10 kHz
Main Core; Bulk Winding (Inductance)
10 kHz to 150 kHz
Bulk Component Shunt Impedances
150 kHz to 400 kHz
Main Windings
400 kHz to ~1 MHz
Main windings, Tap windings etc
In This Test Insulation power factor or dissipation factor (Tan delta) and Capacitance measurement of bushing provide an indication of the quality and soundness of the insulation in the bushing.

In this Test voltage upto 10KV is Applied to Bushing and Winding.There are Two type mode of measured in this method UST & GST Mode.

Insulation Resistance Test(5000 Volts)

Insulation resistance (IR) measurement is the simplest and most widely used test to check the soundness of transformer insulation. This test reveals the condition of insulation (i.e.Degree of dryness of paper insulation), presence of any foreign contaminants in oil and also any gross defect inside the transformer (like failure to remove the temporary transportation bracket on the live portion of tap-changer part).

Winding Resistance Test(25aMPs)

Transformer winding resistance are measured in the field in order to check for any abnormalities due to loose connections, broken strands and high contact resistance in tap
changers as a pre-commissioning checks and compare the measured values with factory
test values.

Voltage Ratio Test

To determine the turns ratio of transformer, Turns Ratio: The Turns Ratio of a transformer is the ratio of the number of turns in a higher voltage winding to that in a lower voltage winding. Transformer turns ratio (TTR) meter available in convenient portable form. They have a hand crank power supply, with the voltages commonly used being very low, such as 12-120 V and 50-60 Hz.
