Product Description

I. General Information:
Transformer DC resistance is a necessary test item for factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department. It can check the welding quality of the winding joint and whether there is turn to turn short circuit in the winding. It can check whether the contact of each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the outgoing line is broken, whether there is broken strand in the parallel winding of multi strand wires, etc.

EPWT series Transformer Ohmmeter, also called DC Winding Resistance Tester is applied to detect the welding quality of winding contactors are in good condition or not, and if there is turn-to-turn short circuit in winding. It also can detect the connecting and its' indicators of voltage on load tap changer are in good condition or not. EPWT is designed specifically to measure DC resistance values of transformer windings and any DC resistance of an inductive device.

II. Features:

• Controlled by high speed SCM, easy to use.
• Selectable current positions, large measurement range, suitable for the DC resistance values measuring of large-medium transformers.
• Full protection functions to ensure safety and availability.
• Auto discharging and discharging indicator.
• Intelligent power management technology, small consumption, less heating.
• True color LCD screen.
• Built-in thermal printer.
• 1000 groups' data storage no lost even power failure.
• RS232 and USB interface, easy communicate with PC and U disk.
