CD23/223 -
Validyne Engineering
The CD23 and CD223 Digital Transducer Indicators are designed for use with variable reluctance and differential transformer transducers. The CD23 accepts input from a single transducer, and the CD223 accepts two switch-selectable inputs, with Zero and Span controls for each input. The indicators provide 5 Vrms, 5 kHz carrier excitation voltage to the transducer(s) and solid state circuitry to amplify, demodulate and filter the transducer output signals. A 3 1/2 digit front panel display is standard, with a 4 1/2 digit display optionally available.

AS-RXFEP RX -
Array Solutions
The AS-RXFEP Receiver protector limits input RF signal threshold from 1 to 150MHz to less than 0.3 Vrms to protect a receiver front end from damage due to nearby transmitted signals. The receiver still actsnormally and measured signal strength is not affected.The circuit uses a multi-stage design of transformer saturation coupling and current limiters. It also incorporates a low voltage GDT to protect from lightning events. These are for receiving only - you cannot transmit through them without damaging the unit.

Signals & Systems India Private Limited
The Display used to monitor the 20Hz and 50Hz current passing through NGT transformer. This could help to monitor the stator earth fault and could record the current every minute. The current shall be displayed in milliamps for both 20Hz and 50Hz. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. The current can be measured using clamp-on CT which would be clamped between load resistor and NGT. It gives an indication of the current values are lower or higher than the set threshold.

Yangzhou Power Electric Co., Ltd
Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.

Analog Devices Inc.
Analog Devices TimerBlox parts are small, accurate, and simple timing devices designed for six basic operations: voltage controlled oscillation (VCO), low frequency clocking, pulse-width modulation (PWM), one-shot generation and signal delay, and power-on reset (POR). TimerBlox devices combine an accurate programmable oscillator with precision circuitry and logic. No capacitors, no crystals, no microcontroller, and no programming are required. A 20 mA source and sink capability enables the devices to directly drive opto-isolators and transformers for electrical isolation. An ideal solution for space-limited applications, each TimerBlox device can be placed at the point of use.

B-1020-C -
ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.
