Step Up Transformer
MagD
-
SCOPE proudly introduces Step-Up Transformer - MagD, specially designed to cater the needs of testing of instrument Transformers. Before new systems are put into service or after any occurrence of fault, the instrument transformers need to be tested for their outputs. It is to be ensured that these instrument transformers are giving proper outputs to the protective relays. MagD is used to plot excitation curves for instrument transformers. Inbuilt voltmeter and ammeter, eliminates the need of external meters for plotting of curves. It can also be used for de-magnetization of transformer cores and also turns-ratio tests can be conducted using MagD.

Automatic Winding Turns Tester
-
This tester has the advantage of high accuracy and efficiency, limited influence due to the form and size of the coil to be analyzed, and fast & easy operation thanks to the precision sensor and microprocessor that adopt the patent know-how developed by the manufacture. This tester, when in operation, does not need any further adjustment and calibration. Just connecting the clip leads to each terminal lug of the coil winding, then the tester instantly shows the exact number of the winding turns on the digital display. Unlike other similar devices, input the data of standard coil to test against is unnecessary. In this way, this tester greatly upgrades the inspection and analyzing efficiency.

Handheld Turns Ratio & Winding Resistance Tester TWR-H
-
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.
