CTC760E Instrument Transformer Analyzer
The CTC760E Instrument Transformer Analyzer performs a range of standard tests for current and voltage transformers. It can assess magnetization characteristics, saturation behavior (ALF/FS), transformation ratio and accuracy, polarity, burden, winding resistance, and remanence. Testing is carried out in accordance with IEC60044-1, IEC60044-6, IEC 61869, and ANSI/IEEE C57.13.1.
Product Details
Features
- Tests CT excitation characteristics below 80 kV using direct-current and variable-frequency (low-frequency) methods for efficient testing.
- Uses the voltage method (secondary injection) to test current transformer ratio and polarity, including transformer bushing CTs.
- The built-in power supply provides an output-current mode for testing CT ratio and polarity and checking the integrity of the CT secondary circuit.
- Supports output up to 200 A with the optional external current booster.
- Tests current transformer secondary winding DC resistance and secondary circuit burden.
- Tests voltage transformer excitation characteristics, ratio, polarity, and secondary winding DC resistance.
- Draws the excitation curve and calculates the knee point in accordance with IEC60044-1 and IEC60044-6.
- Draws 5% and 10% CT error curves and measures CT ratio error and phase displacement.
- Measures CT remanence factor (Kr), magnetizing inductance (Lm), secondary loop time constant (Ts), transient dimensioning factor (Ktd), peak instantaneous error (PIE), accuracy limit factor (ALF), and instrument security factor (FS).
- Draws the current transformer hysteresis loop curve.
- The transparent display presents measured values and curves clearly for indoor and outdoor use.
- A high-speed thermal printer can print test values and curves.
- Automatically checks connecting cables and provides warnings when connections are incorrect.
- Built-in memory stores up to 20,000 winding test values and retains them after power loss.
- Transfers test values to a PC via USB flash drive for report generation and supports software updates using a USB flash drive.
