The Raytech TR-1 is a single-phase transformer turns ratio meter. It is a fully automatic, microprocessor-based instrument that can test ratios up to 4000:1. The TR-1 is designed for highly accurate readings on-site with laboratory precision. It is a lightweight system that comes complete in its own rugged waterproof fieldcase.
The TR-1 has a number of features, including:
- Fully automatic operation: The TR-1 automatically applies a preset test voltage to the high winding side of the transformer and measures back through the low side of the transformer. The results are displayed on the easy-to-read liquid crystal display.
- High accuracy: The TR-1 has a high degree of accuracy and can test ratios up to 4000:1.
- Rugged construction: The TR-1 is housed in a rugged, lightweight, waterproof case.
- Battery operated: The TR-1 is battery operated and can be recharged with line voltage or an optional DC car adapter.
- Reverse polarity protection: The TR-1 has reverse polarity protection to prevent damage to the instrument.
- Continuity test: The TR-1 can also be used to perform a continuity test on a transformer.
- Test current up to 1 A for CT testing: The TR-1 can be used to test current transformers by providing a test current up to 1 A.
- Internal storage of the last 50 test results: The TR-1 can store the last 50 test results for later retrieval.
- RS-232 interface: The TR-1 has an RS-232 interface that can be used to connect the instrument to a computer for data logging or analysis.
The Raytech TR-1 is a versatile and accurate transformer turns ratio meter that can be used for a variety of applications, such as:
- Troubleshooting transformers
- Testing transformers for compliance with standards
- Calibrating other test equipment
- Designing new transformers
The TR-1 is a valuable tool for any electrician, electrical engineer, or anyone who works with transformers.
