Megger Group Ltd.
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.

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.

LXinstruments GmbH
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

BOP Series -
Kepco, Inc.
Kepco's bipolar BOP power supplies are available in 100W, 200W and 400W sizes. For applications requiring higher power, see Kepco's 1KW High Power BOP. For applications requiring higher voltage, Kepco's Series BOP-HV are available in 500V and 1000V models.BOP are high speed power operational amplifiers that can be used to provide dynamically agile voltage for test and simulation. They are not general purpose power supplies. By the nature of the bipolar high speed design, they do not have any energy-storage noise discriminating output capacitors. These power supplies offer ultra low noise and ultra low ripple at the output and are MIL-STD-461 compliant.

Ruetz Technologies GmbH
Ross High Current Switches are available up to 36,000 amps continuous and over 1,700,000 amps 20µsec RC pulse, with voltage ratings of 6 volts to 400kV peak test. Standard Ross high current switches are built with 80 to 120psi air cylinder actuators. Air cylinder or motor operated for high contact force. Arcing contacts optional for closing current. G-10 epoxy glass laminate is standard insulation on most models. G-7 silicone glass is used on models available for RF applications above 100kHz. Most Ross high current switches are available with additional lengths of insulation, where the high voltage contacts need to be spaced at a greater distance from the actuator and control circuit. Voltage withstand value is at least doubled and the interrupt capability is much greater when high current switches are immersed in insulating oil, fluid or SF6 gas. For gas atmosphere, no modifications are necessary; however, oil or fluid immersion requires modification at a slight extra cost.
