Home » GenRad 1621 Capacitance Bridge from IET
The IET GenRad 1621 apacitance Bridge measurement system is a fully self-contained system, capable of taking capacitance measurements in steps as small as 0.1 aF (10-7 pF) and conductivity measurements in steps as small as 100 aU (10-7 µU, equal to a shunt resistance of 1010MΩ). The measurements are 3-wire, with a 2- or 3-wire connection, and is also provided for connecting an external standard for comparison measurements.
Such capabilities and precision are usually associated with a limited frequency range and complex operation. However, the 1621 avoids these problems. Small performance reductions take place from 10 Hz to 10 kHz and operation up to 100 kHz is possible. Balance is achieved by in-line readout switches – easy to adjust and correctly read. All figures of capacity and conductivity, as well as relevant multipliers, are also made available by BCD coded contact closures, which can be used by printers or data equipment for rear connections.
The GenRad 1621 capacitance measurement system is a combination of three integrated instruments: a precision ratio-arm bridge, a very stable oscillator and an extremely sensitive detector. Most of the bridge’s internal standards are enclosed in an insulated housing to reduce the effects of ambient temperature; unused standards are disconnected to reduce shunt capacity at the detector input. The oscillator provides up to 125V or 5A: sufficient signal to be detected, even with an unbalance of only part 108 of 10 pF. The detector contains three meters to help you speed up the balance: one display shows the size and the other two displays simultaneously show the in phase and quadrature components of each unbalance.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
