About OLTC Fitted Transformer
OLTC Fitted Transformer is an instrument in transformers which takes into consideration variable swing proportions to be chosen in discrete advances. Transformers with this instrument acquire this variable turn proportion by interfacing with various access focuses known as taps along either the essential or auxiliary winding. These transformers more often than not have 33 taps from the ostensible transformer rating which, thus, takes into consideration ventured voltage direction of the yield. This is the most present day outline of high voltage transformers used to redress the variety in HV supply voltage. These are accessible in three voltage run I. e. 6KV, 11KV and 33KV. This sort of transformers revises the supply voltage by methods for on stack tap changer switch.

Advanced Voltage Regulation with OLTC
This transformer utilizes a motorized On Load Tap Changer (OLTC) to deliver seamless voltage adjustment. With a tap range of +/-10% in 1.25% increments, it ensures stable output even during fluctuations, enhancing operational reliability for distribution and industrial networks.
Customizable Design for Versatile Applications
Each unit is tailored to match client requirements, from impedance selection (typically 4%8%) to preferred insulation class and rating. Supporting both outdoor and indoor installations, these transformers are ideal for diverse environments and power transmission demands, from 100 kVA to 5000 kVA.
Robust Construction and Safety Provisions
Built from electrolytic copper and CRGO steel, the transformer offers durability and high efficiency. It features comprehensive protection (Buchholz relay, PRV, temperature monitoring), minimized noise (<60 dB), and is painted with epoxy powder for enhanced corrosion resistance, all ensuring optimal service life.
FAQs of OLTC Fitted Transformer:
Q: How does an OLTC fitted transformer benefit power distribution systems?
A: OLTC transformers provide continuous, automatic voltage regulation under load conditions, maintaining stable power supply and minimizing voltage fluctuations without interrupting serviceessential for efficient distribution and industrial applications.Q: What is the process for customizing the transformers specifications (impedance, insulation class, output)?
A: Clients can specify impedance, insulation class, output rating, and other parameters during order placement. The transformer is then designed and manufactured to these requirements, ensuring optimal performance for each specific application.Q: When should the OLTC function be operated, and how does it adjust output voltage?
A: The OLTC (On Load Tap Changer) automatically operates when voltage adjustments are required. Its motorized mechanism shifts taps in 1.25% increments within a +/-10% range, compensating for line voltage changes while the transformer remains energized.Q: Where can this transformer be installed, and what environmental conditions does it withstand?
A: This transformer is suitable for both indoor and outdoor installations. It operates reliably in temperatures from -5C to +50C, with sealed or conservator-type tanks providing protection against diverse environmental challenges.Q: What safety and protection features are included in the transformer?
A: Key protection and monitoring features include Buchholz relay, Oil Temperature Indicator (OTI), Winding Temperature Indicator (WTI), Pressure Relief Valve (PRV), and optional accessories like oil level and temperature gauges, and silica gel breathers for moisture control.Q: How is efficiency and noise level maintained within the products operating range?
A: These transformers employ copper windings and high-grade CRGO steel cores to ensure up to 99% efficiency. The design and robust construction result in a low noise level, remaining below 60 dB at a distance of 1 meter.Q: What standards and certifications are met by this product?
A: The transformer meets IS 2026 and IEC 60076 standards and is BIS certified, ensuring it adheres to stringent quality, safety, and performance benchmarks.
