Product Introduction
This 500kVA distribution transformer was delivered to a Forest electricity in Trinidad and Tobago in 2023, the rated power of the transformer is 500kVA, the primary voltage and secondary voltage of the transformer are 33/6.6kV. The transformer is equipped with high and low voltage fuses for better protection. Because of the fuse, the height of the transformer is much higher than that of the ordinary transformer. In addition, the transformer high and low voltage bushings are tilted at a 45° Angle to better connect the overhead cables. The 500kVA power transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
SCOTECH ensure each one of our delivered transformers had passed the full acceptance test and we remains 0 fault rate record for more than 10 years so far, our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international

How to Choose the High and Low Voltage Fuses for Transformers
When it comes to selecting the high and low voltage fuses for transformers, there are several factors to consider. These fuses play a critical role in ensuring the safe and reliable operation of transformers, which are used to step up or step down the voltage of electrical power.
Here are some key factors to consider when choosing the high and low voltage fuses for transformers:
1. Voltage Rating: The first and most important factor to consider is the voltage rating of the fuse. Make sure to choose a fuse with a voltage rating that matches the transformer's voltage rating to ensure optimal performance and safety.
2. Current Rating: Another critical factor to consider is the current rating of the fuse. Choose a fuse with a current rating that is suitable for the expected load of the transformer to prevent overloading and damage to the fuse.
3. Fuse Type: There are several types of fuses available, including cartridge fuses, blade fuses, and DIN fuses. Choose the type of fuse that is most appropriate for the transformer's design and application.
4. Breaking Capacity: The breaking capacity of a fuse refers to its ability to interrupt a fault current. Make sure to choose a fuse with a breaking capacity that exceeds the maximum expected fault current to ensure reliable operation and safety.
5. Time-Current Characteristics: The time-current characteristics of a fuse refer to its response time to different levels of fault current. Choose a fuse with time-current characteristics that are appropriate for the transformer's application and protection requirements.
6. Backup Protection: In some cases, it may be necessary to provide backup protection for the transformer in the form of a secondary fuse or circuit breaker. Make sure to choose backup protection that is compatible with the main fuse and provides the necessary level of protection.
In conclusion, selecting the high and low voltage fuses for transformers requires careful consideration of several factors. By taking the time to properly evaluate these factors, you can choose the right fuses for your transformer and ensure safe and reliable operation.
