For industries to operate properly, they need a reliable way to regulate their voltage levels. When there’s an error in your machine, it’ll stop working and cause you to lose money. All this can happen from fluctuating voltages because of different loads put on the transformer for the products being produced. Because of this requirement for stability, many industrial businesses are looking for industrial transformer manufacturers who provide them with an On-Load Tap Changer (OLTC). It is a device that allows the transformer to automatically adjust its output voltage without interrupting the power supply.
What is OLTC in Distribution Transformers?
An On-Load Tap Changer is a mechanical device contained inside a transformer that allows the transformer to change the number of coils it has while maintaining its output voltage as well as the load on the transformer. As the input power to your transformer changes, OLTCs automatically change the input coils so that they match the voltage coming into the transformer and keep the output voltage steady. The use of an OLTC in a distribution transformer is critical for ensuring that the power going to your machines is steady and reliable.
Reasons Industries Like to Use OLTC Distribution Transformer
Improved Voltage Regulation
The major benefit of OLTC transformers is that they help ensure a stable output voltage. Industrial operations often experience fluctuating loads as a result of changing production schedules, machine operation or electrical grid conditions.
Reduced Production Interruptions
An interruption in power causes a production shutdown and delay in processing orders. Unlike off-load tap changers, OLTCs adjust the voltage of a transformer without having to disconnect the unit from the distribution system.
Enhanced Equipment Protection
Electrical motors, drives, and automation systems are designed to function within a certain voltage range. Constant fluctuating voltages can cause excessive temperature on these products, malfunction due to damaged insulation, and shorten the life of the equipment.
Better Power Quality
Steady state voltages significantly improve the quality of power used by a facility. Steady state voltages improve the way that equipment operates and decrease the potential for performance issues from under- and over-voltage. Maintaining power quality is essential in industries that are based on precision equipment and automated processes. For this reason, many industrial transformer manufacturers recommend OLTC-equipped transformers for industries seeking greater reliability.
Adaptability to Changing Load Conditions
Electrical loads in today’s manufacturing environment are not consistent. Factories experience varying amounts of electrical demand due to production needs, shift schedules, and seasonal demands. Transformers equipped with OLTCs allow for automatic adjustments to changing load conditions, making them perfectly suited for industrial facilities with varying electrical loads.
Conclusion
OLTC-equipped transformers offer an excellent power delivery solution as electrical infrastructure is being expanded and load variability is increasing. Top industrial transformer manufacturers know how critical it is to reliably distribute electrical power and provide OLTC-based transformer solutions that support uninterrupted and efficient operations in today’s industrial environment.
