new turnS ratio measurement applicationfor the 2293
We are proud to announce the release of the newest functionality of the Tettex 2293 Winding Analyzer – the Turns Ratio Measurement application.
With this addition, the 2293 is the world’s first winding analyzer that combines resistance and turns ratio measurement, demagnetisation and heat run test in one instrument.With the established one-time-connection system all the tests can be done in a row without reconnection.
NEW AKV 9330 for power capacitor testing Tettex announces the launch of a New 300A PD coupler (AKV 9330) for PD testing of large power capacitors. This addresses head-on the twin problems associated with large capacitor PD testing –reduced measurement sensitivity and high test current requirement.By a new approach, AKV 9330 amplifies the PD measuring sensitivity by several folds while simultaneously filtering out the power frequency current up to 300A.It is anideal IEC 60270compliant solutionfor PD Testing of Power Capacitors.
We are pleased to announce “The Motwane Manufacturing Company Pvt. Ltd.” as our new representative for the Indian Market. This arrangement came in to effect as of 2nd October 2012 and covers the entire Hubbell High Voltage Test Business products (Haefely, Hipotronics and Tettex Brands).
The large and well established presence of Motwane in the country convinced us to form this alliance with them and we are sure that the collaboration between our companies will offer a high quality of customer service that will meet your expectations.
Please do note that the contract with our former representative ETM Technologies Pvt Ltd. Gurgaon has ended with immediate effect.
All your queries related to sales and post-sales support should now be sent to our new partner:

NEW DTTS(distribution transformer test system) Distribution transformers are "mass production equipment"; high testing-throughput is a must without compromising quality. Our new DTTS aims at a highly automated test procedure using well-prepared sequences and minimal manual intervention to keep the test duration of a single transformer as short as possible and to avoid human errors.
NEW 2830/2831 The Tettex 2830/2831 is the result of extensive research and years of experience testing dielectric properties of liquid and solid insulating materials. It incorporates a fast and highly advanced procedure to measure Capacitance and tan δ, DC resistance and relative permittivity εr (dielectric constant) of liquid or solid insulating materials.
CTT (cable test teminations) & WPU (water processing unit) Cable test termination systems are used for high voltage testing of power cables. Before high voltage (AC or Impulse) can be applied the power cable need to be prepared and terminated in a special way order to control the electrical field distribution along the ends.
The Tettex 2293 is the result of extensive research and years of experience testing transformers. It incorporates a fast and highly advanced procedure to measure winding resistance. A simple one-time-connection system together with the simultaneous winding magnetization method drastically reduces measuring time.
