Two Output DC Sources
A common issue when testing winding resistance of distribution transformers is the selection of test current. Distribution transformers have high turns ratio, and therefore high difference between rated HV and LV currents. Testing HV and LV winding simultaneously with the same current source can be challenging – test current must be less than or equal to 10% of the HV rated current, which is very often too low for LV winding. For this reason, TWR-H has two output DC sources – one for transformer HV side, and the other for transformer LV side. This way, transformer HV and LV windings can be tested simultaneously using different test currents.
Built-in AC and two output DC sources enable performing multiple tests on a same transformer – winding resistance, demagnetization, turns ratio, excitation current, and phase angle – with a single cable and test setup.
TWR-H is supplied by internal Li-Ion battery. Up to 100 tests can be performed with fully charged battery.
TWR-H has internal SD card of 8 GB memory space. This enables saving tens of thousands of results.
All results from TWR-H internal memory can be easily transferred to a DV-Win software via Bluetooth communication. This allows user to analyze results in the office, to print them, or to create customized test reports. The software is included in the purchase price.
