TRANSFORMER WINDING RESISTANCE METER


Neo Tele Tronix Pvt. Ltd. better known by brand name  NTPL serves in the field of  Electrical and Testing Equipments for over 35 years located in Kolkata, West Bengal.

NTPL manufactures over 60 different types of test and measuring instruments.

This Test set is suitable to measure winding resistance of transformers, single or 3-phase, star or delta connected upto several MVA. Two independent displays read the resistance of both primary & secondary windings simultaneously. However, primary or secondary winding can also be measured separately. DC Power source allows the selected current to flow through the winding /windings and the voltage developed across the winding are sent to instrumentation amplifiers, thereby displaying directly the ohmic value.
