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. Installation of an on load tap changer.
Oltc Maintenance And Install Oil Filter Youtube Mr on load tap changer vacuum model vv installation in power transformer, includes unpacking, installing in the transformer cover, installing the taps connec. Figure 1 – on load tap changer. the tap changer has four essential features: 1. selector switches. these switches select the physical tap position on the transformer winding and, because of their construction, cannot and must not make or break the load current. 2. 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 article briefs about oltc. in off load tap changer transformer, the main supply connection is disconnected while changing the tap. whereas on load tap changer transformer there will be continuous power supply even when tap positions change. the main advantage of oltc is that is can operate without disconnecting.

On load tap changers (oltcs) are indispensable in regulating power transformers used in electrical energy networks and industrial applications. this content explains the technological developments of resistor type oltcs and reactor type oltcs. the general switching principles for oltcs are discussed and oltc applications are presented. 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.
