  • High Voltage Isolation Switch Contact Pressure Tester

    WA1401 - Wuhan Sangao Electrical Test Installations Limit Co.

    Isolation switch is the high voltage switch equipment, it was large and frequently use in power system . The outdoor isolating switch is the only completely exposed in the atmospheric environment electrical equipment, It is also a electrical equipment affected by climatic conditions influence the most direct and most serious. The operating conditions is relatively poor, It is easy to generate fault of mechanical or electrical. Especially the finger contact part is easy to be affected by rain, dust and harmful gas invasion, resulting in poor contact caused fever, provide the spring with contact pressure due to heating and annealing for reducing the pressure, so that more cause finger heat form vicious spiral eventually burn out finger accident. In maintenance often only pay attention to replace the obvious failure and fracture of spring, but spring to reduce the pressure can not judge and replacement, so again in the operation, each finger current distribution by the pressure difference, The greater the difference between the current distribution is not uniform, long-term operation will occur is bad and the overheating. Fever finger will be vicious spiral, a finger contact bad will spread over the entire bad contact. At the same time, there are a lot of isolating switch contact pressure can be adjusted, if in maintenance adjustment pressure is not enough or each finger to adjust the pressure difference will also appear afore-mentioned phenomena.

  • Single-Phase Transformer Winding Resistance Meters

    RMO-TW Series - IBEKO Power AB

    RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software 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. Finally, a user can export all results in the form of a report.

  • AC Fuel Flow Signal Generator

    TA-100 - Tech-Aid Products

    The TA-100 signal generator was designed to facilitate testing of aircraft fuel flow indicators that require two input signals designated as “Drum” and “Impeller”. This generator provides both signals so as to provide a direct interface to the fuel flow indicator under test. The generator also provides switched power out to the unit under test as well as a 5v source for testing the bezel lighting. The original design was built around the requirements for the AMETEK series indicators (pn: 10171 series). This generator simulates a reference and a time delayed signal of appropriate amplitude for an indication of up to 1200pph for the indicator under test. The “PPH Select” switch provides fixed signal delays representing 0, 200, 400, 800, 1000 and 1200pph flow rates respectively, this provides the mechanic with an expedient check of the indicators accuracy. The “PPH Adjust” control allows the mechanic to vary the signal delay throughout the full range and serves as a good method for checking of pointer smoothness from stop to stop. The unit’s front panel also provides test jacks to monitor the “FDR Output” as well as the drum and impeller signals. The TA-100 requires only 28Vdc to operate. This generator provides a very economical approach to any repair facility or flight department as it becomes an alternative to purchasing two bench top signal generators. The TA-100 generator at the very least can provide a simple functional test and eliminate the high cost of exchanging an indicator as a function of troubleshooting the aircraft system.

  • Circuit Breaker Test Equipment

    IBEKO Power AB

    DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.
