Transformer Turns Ratio Meters
-
Vanguard Instruments Company, Inc.
The ATRT-01 S3 is Vanguard’s fourth generation, micro-processor based, single phase, automatic transformer turns-ratio tester. The ATRT-01 S3 uses the IEEE C57.12.90 measuring method to determine the transformer turns-ratio. The transformer turns-ratio is determined by precisely measuring the voltages across the unloaded transformer windings. The ATRT-01 S3’s measuring circuitry self adjusts before each measurement to ensure turns-ratio accuracy. Two selectable test voltages, 4Vac and 40Vac, offer flexibility in testing different types of transformers.

The JSC family of devices provides a highly reliable way to determine if voltage is present downstream of the disconnector or circuit breaker knives during zero-energy shutdowns. They dramatically increase the safety of personnel performing maintenance on electrical equipment. When voltage is present downstream of the disconnector knives, one or more LEDs on the JSC-88A will remain illuminated. The JSC's compact design allows for direct installation on the disconnector door, starter, or control panel.

Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.

For decades, Motwane Voltage Detector has been a standard for international quality and safety ratings. Voltage detectors are used to signal the presence of voltage in a conductor since they make visible what we normally can’t see. Its application lies mainly in safety reasons during research, or when a service operation is under way. Most of the time, the monitored conductors come from low impedance sources whose voltage and energies are considered life-threatening.

Low Voltage DC / Battery Powered High Voltage Amplifiers
WMA-005 And WMA-005LF
-
The Falco Systems WMA-005 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-005LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.
