|
Designed to measure DC winding resistance of highly inductive test objects Transformers, Generators, Motors etc. |
|
|
| |
Quick stabilisation of reading even on large test objects by deploying high open circuit voltage |
|
| |
Saves down time, measurement of resistance of 1/2/3 windings simultaneously |
|
| |
Available for continuous testing powerful, truly continuous DC source with excellent heat management through forced cooling |
|
| |
Total instrument and human safety ensured through automatic & quick back-emf discharge after test completion |
|
| |
Discharge possible through either voltage or current lead in case of accidental lead disconnection operator risk is minimised |
|
| |
Quick & simple tool to check the condition of OLTC discontinuity during tap change, if any |
|
| |
In-built stable DC source and direct display of resistance value |
|
 |
Single compact instrument |
|
|
No need to spend time in bridge balancing |
|
|
No need of manual calculation |
|
|
| |
Accurate comparison with factory test results at specified temperature possible through Temperature Measurement Channel* & Automatic Temperature correction* facility |
|
| |
Increases testing throughput as complete operation is possible through external PC/Laptop* |
|
| |
Easy to use self guided operation through interactive menu and keyboard |
|
| |
No need to compensate lead resistance as Kelvins Four wire measurement method is used |
|
| |
