Soken DAC-CTC-7 - Current Transformer Checker
An instrument transformer that rated secondary current (voltage) is very low is usually composed of
electric devices like electronic power meters, watt-hour meters or transducers, so that the secondary
current (voltage) can directly be supplied to electronic circuits in the devices. DAC-CTC-7 for CT and
DAC-VTC-7 for VT are applicable to test such transformers and measures ratio errors and phase angles
Specimen and application
Measuring ratio errors and phase angles of low current transformers (CT) or low voltage transformers (VT) in watt-hour meters, smart meters, digital current meters, and different transducers.
Two-Mode to measure
Two measuring modes are available. One of them is a comparison measuring mode which compares a reference CT (VT) and a CT (VT) under test. Another one is an absolute measuring mode which measures only a CT (VT) under test. Because a suitable CT (VT) sorted from mass productions in the absolute measuring mode can be used as a reference one in the comparison measuring mode, no need to prepare any reference CT (VT) especially.
Absolute Measuring Mode
Comparison Measuring Mode
- The wide Phase angle of 0.0 to 2000 minutes.
- Fast measurement.
- Light in weight and compact in size.
- Simple operation and clearness display.
|Test Current/ Test Voltage range||2% - 120% of rated Current / Rated Voltage|
|Phase Angle||0.0mim - +/-2000min|
|Ratio Error||0.00% - +/-20.00%|
