Transformer Test

TEST

Each transformer must be tested before leaving the factory. The routine tests include: •Ratio, Polarity, and Phase Relation •Resistance •Applied Potential •Induced Potential •Loss Test •Leak Test •Operation tests of all devices: All electrical and electro-mechanical devices shall be operated both in auto and manual mode for proper sequencing/staging and function.

If you need special tests like short circuits, DB Transformer can do that too.

DESIGN PERFORMANCE TEST

The design performance tests include the following:
*Temperature Rise: Our automated heat run facility ensures that any design changes meet ANSl<sup>® and IEEE® temperature rise criteria.
* Audible Sound Level: Ensures compliance with NEMAO requirements.
* Lightning Impulse: To assure superior dielectric performance, this test consists of one reduced wave,two chopped waves and one full ave in sequence,precisely simulating the harshest conditions.
* Other perfomance tests such as short-cicuit capability test,liting and moving devices test can be execuled while specified by the customer.</sup>
