Soken DAC-VCTT-8 - Instrument Transformer Test Set
DAC-VCTT-8 is an automatic balance bridge incorporating a current comparator-type transformer. The meter is desirable for measuring ratio errors and phase angles of instrument transformers according to the international standards IEC 60044-1 and -2. Combining an optional different-ratio adapter, DAC-RAC-2/RAV-2, different-ratio testing is also available.
Options: Ratio Adaptor DAC-RAV-2/RAC-2
Range of ratios to be set
Ks: Transformation ratio of a measurement standard
Kx: Transformation ratio of an instrument transformer to be tested
VT: DAC-RAV-2: Ks/Kx: 0.5000 - 2.0000
CT: DAC-RAC-2: Ks/Kx: 0.5000 - 2.0000
Optional Burdens
- Current transformer (CT) testing in accordance with the current ratio error test of the international standard IEC 60044-1 is available.
- Voltage transformer (VT) testing in accordance with the voltage error test of the international standard IEC 60044-2 is available.
- The ratio error, phase displacement, test voltage, test current, and test frequency of CT/VT can be measured.
- Units of indication, either “%” or “RCF” (Ratio Correction Factor) for the ratio error, and either “Min “(minutes) or “Crad” (centiradians) for the phase angle, are available. Thus, it is appropriate for ANSI/IEEE tests.
- USB interface is a standard fixture.
- Error values of standard VT/CT can be registered, and automatically compensated.
- Registration: 10 units for each VT and CT (Test point: 20 points for every unit)
- Different-ratio testing is available by incorporating an optional CT or VT different-ratio adapter.
- An internal burden compensation circuit realizes the internal burden of DAC-VCTT-8 as small as 0.1VA.
