The (OLTC) Industrial Transformers that we manufacture are available in HT AVR step control type with OLTC. It also improves the power factor and enhances the energy efficiency. These (OLTC) industrial transformers perform as a regulation panel which can better save energy and electric power for greater profits.

On Load Tap Changer (OLTC) is used with higher capacity transformers where HT side voltage variation is frequent and a nearly constant LT is required. OLTC is fitted with the transformer itself. Multiple tapping from HV windings are brought to the OLTC chamber and contacted to fixed contacts. Moving contacts rotates with the help of rotating mechanism having a spindle. This spindle can be rotated manually as well as electrically with a motor. Motor is connected in such a way that it can rotate in both the directions so as to rotate the OLTC contacts in clockwise and anticlock-wise direction. Two push buttons are fitted on the LCP (local control panel) to rotate the motor and hence the OLTC contacts in clockwise and anti-clockwise direction. This movement of contacts thus controls the output LV voltage of the transformer. So rotating of OLTC contacts with spindle or push buttons in this way is a manual process. In case this process of rotating the OLTC contacts and hence controlling the LV side voltage is to be done automatically then a RTCC (Remote Tap Changer Controller) is installed with the transformer HT Panel. The RTCC sends signals to LCP and LCP in turn rotates the motor as per the signals received from the the RTCC

Ultra-Isolation Transformers are important component parts in numerous power supply and electric appliance. We have applied latest technology such as arrangement wire winding without bobbing, the whole transformer is impregnated under vacuum-pressure up to insulation and class F or H to manufacture our range of transformers. The input and output voltage can be developed as per the clients specification.

Some of the salient features of our range are given below:

• High level of isolation
  
• High quality neutral-ground bond
  
• High level of common-mode noise rejection
  
• Conversion from Delta to Wye or the other way around
  
• Easy to change voltage taps
  
• Custom design for specific system
• 
  

Applications:

• Integrated in power conditioner at input or output
  
• Any system requires isolation and shielding.
