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.

Renesas Electronics Corp.
Renesas' family of low-side FET drivers are very high-speed matched dual-drivers capable of delivering peak currents of 2.0 amps into highly capacitive loads and excellent at driving large capacitive loads with minimal delay and switching times. The high-speed performance is achieved by means of a proprietary "Turbo-Driver" circuit that speeds up input stages by tapping the wider voltage swing at the output. Improved speed and drive capability are enhanced by matched rise and fall delay times. These matched delays maintain the integrity of input-to-output pulse-widths to reduce timing errors and clock skew problems. This improved performance is accompanied by a 10 fold reduction in supply currents over bipolar drivers, yet without the delay time problems commonly associated with CMOS devices. Dynamic switching losses are minimized with non-overlapped drive techniques.

GAO Tek Inc.
GAOTek provides state of the art, professional grade Ohmmeters for sale to the United States, Canada and Globally. GAOTek Ohmmeters are portable instruments that accurately measure electrical resistance between two points on a circuit. The Ohmmeters have their own power supply through their own battery, and are needed when the two probes (red: positive side of circuit, black: negative side of circuit) are connected to the two points in the circuit where the desired measurement is to take place. The circuit is turned off, which is when the ohmmeter sends its own current through the circuit. Units of Ohms, symbolized by the Greek letter Ω (Omega), are used as a unit of measure when measuring electrical resistance. In accordance with Ohm’s law, when the current is passing through a circuit is at its maximum, the resistance is said to be the smallest.
