Transformer Tap Changer

A Transformer Tap Changer is utilized to increase or decrease voltage.  A Transformer Tap Changer has the ability to alter the level of current it can draw, or tap, from the supplying energy circuit.  A really easy way to understand this process is to think of a water faucet.  Just as turning the handle on a water faucet alters the flow of water, a transformer tap changer alters the flow of electrical current.

The way a mechanical Transformer Tap Changer operates is by physically making a new voltage connection before releasing the old voltage connection. By utilizing multiple tap selector switches; this connection switch can be easily accomplished. To avoid creating high circulating currents, a Transformer Tap Changer uses a diverter switch to temporarily place large diverter impedance in series with the short-circuited turns.  This process solves the possibility of problematic open and short circuited taps.

Designs of Transformer Tap Changers

There are several different types of transformer tap changers and they handle a variety of power source needs.  We will explore the various Transformer Tap Changer designs further as follows:

  • Off circuit Transformer Tap Changer – This is a de-energizing type of tap which is used only in applications in which a loss of power supply can be tolerated.  This type of transformer tap changer is often found in high voltage designs.  Off circuit tap changers are also found in power distribution networks on the primary winding where they handle variations within normal ratings and within a narrow band.
  • On load Transformer Tap Changer – This type of transformer is also known as an under load tap changer and is designed to change back and forth between the second and third tap positions.   On load transformer tap changers are generally classified as fully electronic, electronically assisted, or mechanical.  They are often outfitted with a complex and more costly on load tap changing mechanisms.  This type of transformer tap changer is employed in those applications where uninterrupted supply must be guaranteed during tap changes.

  • Reactance Transformer Tap Changer – This type of transformer uses a dedicated, preventive, autotransformer winding and usually designed to indefinitely sustain off tap loading.  In this scenario, the autotransformer winding functions as a diverter impedance.  When this type of tap changer operates in oil, allow for additional inductive fly back that will be generated by the autotransformer.   
  • Thyristor-assisted transformer tap changer – This type of tap changer uses thyristors to take the on load current.  At the same time, the main contacts handle the change over from one tap to the other. When operating in this sequence, arcing is prevented on the main contacts with the additional benefit of potentially longer service life between maintenance periods.
  • Solid state tap changer – This type of tap changer is the result of relatively new developments.  This new development involves thyristors which are utilized to pass and switch the load current, all in steady state.  Typical applications for solid state tap changers involve smaller power transformers.
