WER TRANSFORMER

most every place where people live and work you will find at least one transformer, behind the scenes keeping the supply o

he escalator in the department store, the hotel lift, the office computer, the oven in the local bakery, the farm machinery o

ochemical plant. Nobody gives it a second thought to the important role it plays in the overall power supply. Less you are in

rgy business ensuring grid reliability and stability.

quality of a transformer is of utmost importance for safety, industrial and financial reasons.

T & V.T

The behavior of current and voltage transformers during and after the occurrence of a fault is cr

electrical protection since errors in the signal from a transformer can cause maloperation of the

ays.

In addition, factors such as the transient period and saturation must be taken into account when

ecting the appropriate transformer.

B & Disconnect or

cuit-breakers and disconnect ors lie at the heart of any switchgear installation. However, as well as being extremely

reliable they must also be able to ensure sustained economy and long service life. Consequently, the demands mad

uit-breakers and disconnect ors are stringent:

Dielectric strength test.

Open and close timing test.

Contact D.C resistance test.

Powerful, maintenance-free operating mechanisms.

of the primary reasons why you would need high voltage cable testing is if there were a problem with the installation or if

a mis-wire. Our Power Services Team can introduce the most advanced high-voltage cable tests and installation

he people living or working in residential, commercial and industrial installations,icularly the operators and personnel who are in close operation and contact with

ctrical systems and machineries, should essentially be protected against possiblectrification. To achieve this protection, earthing system is tested,igned and installed according to the standard requirements by ohm electric.
