The Raytech TR-Mark III is a fully automatic, microprocessor-based, single and three-phase transformer turns ratio test system. It is designed for highly accurate readings on-site with laboratory precision. It is the most accurate system available.
The TR-Mark III has a number of features that make it a versatile and reliable tool for transformer testing.
The Raytech TR-Mark III is a versatile and reliable tool for transformer testing. It is easy to use, safe, and accurate. It is a valuable tool for electrical engineers and technicians who need to test transformers on-site.
Features Include:
- Automatic test sequence: The TR-Mark III can automatically apply a test voltage to the transformer and measure the turns ratio. This eliminates the need for manual intervention, and it ensures that the test is performed correctly every time.
- Automatic test voltage range: The TR-Mark III can automatically select the correct test voltage range for the transformer being tested. This ensures that the transformer is not damaged by excessive voltage.
- Graphical tap changer display: The TR-Mark III can display a graphical representation of the tap changer position on the transformer. This makes it easy to see the current tap position and to make adjustments as needed.
- Tap changer interface (In- and Output): The TR-Mark III can be connected to the transformer's tap changer to automatically adjust the tap position during testing. This eliminates the need to manually adjust the tap position, and it ensures that the test results are accurate.
- Load on test object <0.05 VA: The TR-Mark III has a very low load on the test object, which minimizes the impact of the test on the transformer.
- Measures Power transformers, PT's and CT's: The TR-Mark III can measure the turns ratio of power transformers, potential transformers (PTs), and current transformers (CTs).
- Displays % error vs. name plate value: The TR-Mark III can display the percentage error between the measured turns ratio and the nameplate value. This information can be used to identify transformers that are out of tolerance.
- Automatic phase vector detection: The TR-Mark III can automatically detect the phase vector of the transformer. This information can be used to ensure that the test results are accurate.
- Enhanced heavy-duty protection circuitry: The TR-Mark III has enhanced heavy-duty protection circuitry that protects the transformer from damage during testing.
- Extremely rugged (can withstand a drop test of 1 meter): The TR-Mark III is extremely rugged and can withstand a drop test of 1 meter. This makes it a reliable tool for field testing.
- Data exchange via USB-Key: The TR-Mark III can export test results to a USB key for easy transfer to a computer.
- Internal Printer: The TR-Mark III has an internal printer that can print test results.
