  • Megohmmeter Insulation Tester

    AMIC-30 - Amperis sl

    The AMIC-30 insulation tester is a small portable meter designed to measure insulation resistance in electrical and telecommunications installations, cables, motors, transformers and other equipment. The test voltage can be programmed in steps from 10 V to 1000 V. The instrument can measure both insulation resistance over a wide range (0,1kΩ...100GΩ), and insulation leakage current, capacitance and other parameters. All test results can be stored in the internal memory and sent to a computer via the included wireless USB receiver. The meters are supplied with rechargeable Ni-Cd batteries.

  • Micro-ohmmeters

    MMR-650 - Sonel S.A.

    Designed to measure very low resistances of both resistive and inductive types of objects, including amorphous core transformers. This product is made to be used in power plants, railways and maintenance companies, to measure welded and soldered connections, equipotential bondings, earthing conductors, contacts, bolted connections, windings of motors and power transformers and other resistive and inductive objects. MMR-650 can be also utilized on a production lines (eg. at the final production control stage). An innovative combination of a high-performance measuring device with a modern user interface and advanced data management system. Wireless data transmission, enhanced system of 2D codes and ability to print labels to identify test items, all contribute to bringing new quality of work and allow the user to perform a wide range of measurements.

  • Single-Phase Transformer Winding Resistance Meters

    RMO-TT Series - IBEKO Power AB

    RMO-TT series is perfect for measuring winding resistance of inductive objects such as power and distribution transformers or autotransformers. Additionally, every transformer resistance meter from RMO-TT series can analyze:tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.Transformer demagnetization can also be performed with all RMO-TT instruments.The series is consisted of 3 models, with maximal test current from 40 A (RMO40TT) to 100 A (RMO100TT). RMO100TT is the only portable transformer resistance meter in the market with 100 A DC output current.The three independent channels enable testing of three windings in series. Consequently, a user can measure winding resistance in every tap position of an on-load tap changer without discharging between the tests.In addition to winding resistance measurement, a user can perform a detailed on-load tap changer analysis by analyzing recorded graphs (10 kHz sampling rate) and by measuring vibrations on an external tap changer tank.All RMO-TT instruments have a built-in tap changer control unit. Because of this, it is possible to remotely control on-load tap changer (OLTC) directly from the device. Also, a user can program DV-Win software to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test.All results can be exported in the report format.

  • Adjustable Press Plate Bed of Nails Testers

    Protector Adjustable Family - Test Electronics

    Designed for testing heavy massive boards. Boards with heavy components like large transformers and inductors can destroy normal test fixtures. This design utilizes a 3 plate system where an internal lever actuated sub plate containing the test pins raises to probe the circuit board when the handle is pulled. Heavy boards can bend and break exposed test pins. Similarly large boards which need to be probed by very small delicate test pins can also benefit from this protected test fixture design. This fixture is recommended in situations where there is a high board mass to pin size ratio and pin protection is required. Front and rear panel modular inserts allow for easy updates and customizations to the user hardware interface.
