Sigma Tek, Inc.

Sigma Tek, Inc.

These airspeed indicators have unrestrained movements.These instruments are actuated by ram air and ambient atmospheric pressure obtained from the aircraft pitot and static pressure systems. A moveable pointer and a fixed dial indicate airspeed with the zero index at the 12 o??lock position. Temperature compensation is internal and there is no external zero adjustment. Pointer damping is internally adjustable.

Transformer Turns Ratio Testers

IBEKO Power AB

IBEKO Power AB

Transformer turns ratio testers from TRT series are DV Power instruments mainly designed for the measurement of power transformer turns ratio. Also, they measure transformer excitation current and phase shift. Special tests, such as automatic vector group detection and magnetic balance, can be performed on three-phase transformers and three-phase autotransformers.All models, except TRT03 series, have a built-in true three-phase power source, which is necessary for testing turns ratio of transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.DV Power turns ratio testers can output various test voltages for different applications. From the extremely low test voltage of 1 V AC that enables turns ratio verification of the majority of current transformers, up to the highest test voltage of 500 V AC that provides the most accurate turns ratio testing of power transformers used in power generation and transmission. By using the external booster, test voltage increases up to 5 kV AC in order to successfully test capacitive voltage transformers.All DV Power turns ratio testers have a built-in tap changer control unit. Because of that, it is possible to control the on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, the instrument and included DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option significantly facilitates and shortens the turns ratio testing time.TRT turns ratio testers use the same set of cables as three-phase winding ohmmeter & tap changer analyzers from the TWA series. Consequently, it enables one-time cable setup for performing eight tests:turns ratioexcitation currentphase anglemagnetic balancevector group detectionwinding resistanceon-load tap changer DVtestand demagnetization.

MEATEST, s.r.o.

MEATEST, s.r.o.

Impedance Calibrator is to replace countless single value RCL standards with one calibrator that can switch between the standards like a CD changer in your car. The calibrator contains stable and temperature independent resistance standards, partial capacitance standards and partial inductance standards, simulated by RC T-type passive network. Calibration values of both complex parameters of partial standards are displayed on large LCD screen in preselected pairs of parameters as well as voltage, current and frequency readouts from built-in test signal meter. OPEN and SHORT reference positions are available as well.

PPS Clamp Transformer

Techimp HQ S.r.L

Techimp HQ S.r.L

PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.

MIL-STD-1553 is a military standard published by the United States Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus. It was originally designed for use with military avionics, but has also become commonly used in spacecraft On-Board-Data-Handling (OBDH) subsystems, both military and civil. It features a dual, redundant, balanced-line, physical layer; a (differential) network interface; time division multiplexing; half-duplex command/response protocol; and up to 31 remote terminals (devices).
