MECO TTR8100 Transformer Turns Ratio Meter Instruction Manual

MECO TTR8100 Transformer Turns Ratio Meter

Product Information

• The MECO TTR8100 is a portable Transformer Turns Ratio Meter. It is designed to accurately measure the turns ratio, excitation voltage, current, phase angle, and deviation of 1-Phase and 3-Phase Transformer VT/CT. The TTR8100 ensures the correct turn ratio and quality of the transformer. It also checks for live test points, short circuit, open circuit, and reverse polarity before each measurement.
• The TTR8100 features a graphical and literal illustration of measurements and connections on a large backlit dot matrix LCD display. It displays turns ratio, deviation, secondary output, excitation voltage and current, phase angle, and nameplate transformer/VT/CT values in one page for easy interpretation. It can store 4096 files of transformer nameplate values and measuring data. The meter offers ten test frequencies (50~400Hz) and nine types of 3-phase winding connections pre-installed. It also supports wireless Bluetooth communication with a PC.
• Other features include the ability to select a filter to remove field noise, record measurements with date and time stamp, a powerful lithium battery with built-in charging circuit, user programmable RCF (Reference Correction Factor) to correct accuracy within 1% error, PC application software included, and a friendly file system for easy on-site data retrieval and nameplate values management.
• The electrical application ratio range for VT/PT is autoranging from 0.8000 to 10000:1 with an accuracy of (%of Reading) 0.8000 to 999.99, 1000.0 to 4999.9, and 5000.0 to 10000. For CT, the ratio range is autoranging from 0.8000 to 2000.0 with an accuracy of (%of Reading) 0.8000 to 2000.0. The excitation signal for VT/PT mode is 34Vrms max, and for CT mode, it is auto level 0 to 1A, 0.1 to 20Vrms. The meter supports excitation current display in the range of 0 to 1000mA and excitation frequencies from 50Hz to 400Hz. The TTR8100 comes with a 5 large dot matrix LCD display (240×128) with backlight for easy viewing. It is powered by a rechargeable lithium battery with a capacity of 3400mAh, providing  over 10 hours of continuous operation. The battery life isindicated as a percentage. The meter includes a universal input battery charger with a charging time.
• Transformer is a very important element in the Electric Power Distribution System. It needs to be maintained from time to time to guarantee smooth power supply at consumer end.
• MECO TTR8100 is portable instrument for accurate measurement of 1-Phase & 3-Phase Transformer VT / CT Turns Ratio, Excitation Voltage, Current, Phase Angle and Deviation. TTR8100 ensures the Correct Turn Ratio and Quality of the Transformer.
• It checks live Test Points, Short Circuit, Open Circuit and Reverse Polarity before each measurement.

Product Usage Instructions

1. Before each measurement, ensure that the test points are live and check for short circuit, open circuit, and reverse polarity.
2. Turn on the TTR8100 by pressing the power button.
3. Connect the TTR8100 to the transformer using the appropriate cables and connectors.
4. Select the desired test frequency using the frequency selection buttons.
5. Ensure that the filter setting is appropriate for the measurement (slow, normal, or fast) to remove field noise.
6. Press the measurement button to start the measurement process.
7. Wait for the measurement to complete and observe the results on the LCD display.
8. If desired, record the measurement with date and time stamp for future reference.
9. If necessary, correct the accuracy of the measurement using the user programmable RCF.
10. To communicate with a PC, enable the Bluetooth function on the TTR8100 and establish a connection with the PC.
11. For data retrieval and nameplate values management, use the included PC application software.
12. To recharge the battery, connect the universal input battery charger to the TTR8100 and wait for the charging process to complete.
