Description
The Capacitance & Tan Delta Model- QCTD -1Kis transformer arm ratio type Bridge. It is a special development for accurate capacitance and tan delta tests on electrical insulation systems
The Bridge is provided with Modes Selector switch so that once the object is connected; it can be measured in different modes without handling the test leads
Both Measurements of Capacitance & Tan Delta built in Power Supply Unit, Standard Capacitor and Balancing Bridge Unit.
Provision of calibrator to quickly verify the proper operation and calibration of the bridge.
Specially designed for Engineering Colleges LabTest voltage 1000V. This low voltage makes the instrument very safe to operate and easy to understand the concept of Capacitance and Tan Delta testing.
Provision of Guard terminal. No external automatic guard potential regulator is required.
Three different measurement modes can be conveniently selected by a Selector Switch.
Suitable for both grounded as well as ungrounded objects.
