Handheld Turns Ratio & Winding Resistance Tester TWR-H -
Amperis sl
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.

NI
2-Channel, 8 V, ±3 A PXI Programmable Power Supply—The PXIe‑4154 is a specialized programmable power supply for battery simulation. It is designed to simulate a lithium‑ion battery cell’s transient speed, output resistance, and 2‑quadrant operation (source/sink). Critical to many RF and wireless applications, the simulator’s fast transient response time allows it to rapidly respond to changes in load current with minimal voltage dip, which makes the PXIe‑4154 ideal for powering devices under test (DUTs) such as RF power amplifiers, cellular handsets, and a variety of other mobile devices. To model the behavior of a battery more accurately, you can use the onboard programmable output resistance to simulate a battery’s internal resistance. For quiescent and standby current measurements, the PXIe‑4154 features integrated current measurement.

Megger Group Ltd.
AC insulation tests are a popular response to the increasingly demanding industrial, power and domestic marketplaces. Insulation materials have had to become more efficient to keep up with demand; more efficient equipment requires less insulation material to meet the minimum acceptable value of insulation resistance. In turn, cables have become smaller and lighter. However, under certain higher stress testing conditions such as DC testing, cables like Crossed Linked Polyethylene (XLPE) can quickly degrade.
