Can I get a replacement Basler transformer?
Custom low VA transformers are replaced directly through the original OEM, while single-phase and three-phase Power Potential Transformers (PPTs) for AVRs and excitation systems are quoted by our local sales representative.
Basler Electric designs and manufactures a wide range of dry-type transformers that support both the Power System industry as well as Industrial applications.
**Power Potential Transformers (PPTs) for Automatic Voltage Regulators (AVRs)**
Power Potential Transformers are used to step down low and medium power system voltage signals to lower levels that can be safely used by control equipment. In the context of Automatic Voltage Regulators, a PPT provides the appropriate voltage input so the AVR can provide power to the exciter.
For most Basler AVRs, applicable single-phase PPTs are listed in our online catalog under the Accessories section for each AVR model. These listings help you match the correct transformer to your specific regulator. Once the appropriate PPT is identified, your local Basler sales representative can provide pricing information and expected lead times.
**Three-Phase PPTs for Excitation Systems**
Basler also supplies three-phase PPTs designed for use with our excitation systems. These transformers are often engineered to work as part of a complete excitation solution, providing the three-phase sensed voltage required for accurate control and protection of generators.
Typically, three-phase PPTs are:
- Quoted as an integral component of a new excitation system, or
- Provided as a spare part for an existing Basler excitation system.
Because they are frequently application-specific, these three-phase PPTs may not appear in the online catalog. If your installation does not already have a defined PPT, Basler excitation application engineers can work with you to:
1. Review your system parameters (voltage levels, connection configuration, burden, insulation requirements, and standards).
2. Determine which Basler PPT configuration will meet the requirements of your excitation system.
After the appropriate PPT has been selected, your local Basler sales representative will supply detailed pricing and lead-time information.
**Low VA Transformers for Industrial OEM Applications**
In addition to PPTs, Basler Electric manufactures smaller, low VA-rated transformers that are widely used in industrial OEM equipment. These transformers are typically custom-designed to meet the mechanical, thermal, and electrical requirements of a specific piece of equipment. Common applications include:
- Lighting equipment
- HVAC systems
- Industrial ovens
- Industrial irrigation systems
- Other specialized industrial control and power distribution equipment
Because these transformers are customized for individual OEMs—often with unique voltages, mounting styles, and approvals—replacements are obtained directly through the original equipment manufacturer. This ensures that the replacement transformer matches the original design and complies with the equipment’s safety and performance certifications.
If you need to identify the correct OEM contact for a specific Basler-manufactured transformer, you can reach out to Basler’s Magnetics Customer Service department. By providing the transformer markings and any available nameplate information, they can help you determine the associated OEM and guide you to the proper source for a replacement unit.
