Oltc Installation Youtube In this video, oltc is explained with example with respect to following points.1. structural aspects2. working principle3. switching and diverter chamber4. d. Each tap corresponds to different transformation ratio. for initial installation we need to choose a suitable tap as per our voltage levels. tap changers provides 5 to 20 % voltage range for voltage regulation. an on load tap changer has 3 major steps: a. tap selector it selects the appropriate tap. b. fixed contact these contacts hold a.

Dear viewers, in this video full tap changing procedure is shown with explanation. what is oltc,necessity of oltc, location of tappings, why tapping are take. An oltc certainly cannot be operated under such conditions. this fact must be taken into account during the planning stage of the pst design [2], [3], [4], [6], [12]. there are three methods of solving the above mentioned problem: one way of decreasing the recovery voltages is to install screens between the windings. The world mainly uses resistor type oltc’s and have done so for 90 odd years. the largest producers of oltc’s – reinhausen and abb offer some very good insight to operation of oltc’s, but if you are an engineer involved with transformers and don’t understand these principles, maybe further training is needed rather than posting stupid.

The oltc selector arrangement has 16 steps and 17 positions. in the diagram, the oltc is connected to tap 4 while changing from tap position 4 to tap position 5. first, m 1 opens, transferring the load current via a 1 with resistor r 1 in series. then a 2 closes, putting resistors r 1 and r 2 in series across taps 4 and 5. This instruction provides information of on load tap changer (oltc) transportation, installation, adjustment, test and commissioning. it gives detailed instruction for oltc mounting onto transformer and set forth maintenance interval criteria during product operation. safety notice is also mentioned for every process.
