2293

Winding resistance meter with one-time-connection system

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.

The simultaneous winding magnetization (SWM)

method guarantees fast and reliable measurements

even on large power transformers with delta windings

on the low voltage side, where stable measurements

can be seldom reached using traditional winding

resistance measurement instruments.

In addition, the new demagnetization function

eliminates the magnetic remanence in the core after the

application of a DC voltage. This feature can be used

before performing other tests such as frequency

response analysis (FRA), transformer turns ratio

measurement (TTR) or recovery voltage measurement

(RVM) which are adversely affected by remanence

effects.

The transformer is discharged by a state-of-the-art

discharge circuit in a fraction of the time taken by other

instruments. The discharging function and the

“Caution” indicator continue to operate even when line

power is lost.

FEATURES AND BENEFITS

visualization

 Unique simultaneous winding magnetization method

(SWM), equivalent to traditional equipment with up to

100 A test current

 Tap changer control signal

 Heat run function and 6 temperature measurement

channels with automatic resistance value correction

 Data transfer over USB memory-stick or direct to PC

APPLICATIONS

Resistance measurement and demagnetization function for

all types of highly inductive test objects.

 Power transformers

 Distribution transformers

 Generators and motors

 Instrument transformers

The 2293 is a valuable tool for factory test, acceptance test

and regular maintenance.

A test solution optimized for easy and fast

winding resistance measurement on power and

distribution transformers as well as motors and

generators.
