The OMICRON Transformer Diagnostic System is a unique test equipment which provides automatic testing of important transformer parameters within one portable system.The test system is comprised of the CPC 100 Multifunction Primary Test System and the CP TD1 Tangent Delta unit. The patented CPC 100 is the main control unit for the test system and the CP TD1 unit is used for testing of insulation condition.
Benefits
- No need for multiple test sets
One system for multiple tests
Eliminates the need to train on multiple devices
All test results stored in one device and in the same format - Field Ruggedness with Laboratory Precision
High precision in a rugged design
Excellent line-frequency suppression in the presence of electrical and magnetic interference
High precision components for measuring voltages and currents and a gas-insulated reference capacitor for capacitance and Tan delta measurement - Portable
Easy transportation by single person -heaviest component:29kg (64 lbs)
Practical handling on and off-site with a custom-built trolley with easy and quick break-down into single components - Frequency Sweeps
Testing at different frequencies with switch-mode power amplifier technique
Detailed analysis and accurate fault location by the measurement of leakage reactance, ratio, capacitance and tangent delta - Automated Testing and Reporting
Test plans and parameters can be prepared off-line on the computer. This reduces the time for set-up in the field Tests are executed automatically. This reduces errors in manual measurement and the recording of data.
Reports are generated automatically which reduces the time required to complete the overall test procedure.
The reports can be exportet to MS-Excel™ format which enables easy manipulation for detailed analysis of the results such as trending and graphing.
Applications
- Winding resistance
- Turns ratio and excitation current
- On-load tap changer condition
- Leakage reactance
- Insulation condition (capacitance, tangent delta, power factor)

Further Features
- Integrated test voltage generator for voltages up to 12kV with variable test frequency of 15 … 400Hz
- Safety appliances such as: emergency stop, signal lights and warning sound, ground loop control, cable connection check and current loop control
- Self calibration of the signal processing path
Easy Operation
After connecting the test cables to the test object, the setting and operation of the whole test is performed with the CPC 100. The CP TD1 is connected via interfaces to the CPC 100 and thus does not need further control elements. Besides mode selection, a compensation to the conditions at nominal temperature (20°C, 68°F) is possible. If reference values for Cx (C ref) and the dissipation factor (DF ref) are known, an automatic assessment is possible at the test location. If tests at several test voltages and different frequencies are to be analyzed, a fully automatic test sequence can be recorded.
If the measuring frequency is equal to the mains frequency, the influence of line frequency interference is automatically blanked with an innovative measurement technique. If higher selectivity or precision is desired, the measurement bandwidth can be reduced to ±5 Hz and averaging of up to 20 results can be activated. All measurement results and test object data can be saved at the test location in XML format, which allows an easy transfer to database applications. For printing the test report and for further processing of the data (e.g. with MS EXCEL™) it is possible to transfer it to a PC.
