LV Iron Core Shunt Reactors
-
Iron core Shunt Reactors act as an absorber of reactive power to increase energy efficiency of the power system. Shunt Reactors are used in order to compensate capacitive reactive power generated by long and lightly loaded transmission lines as well as underground cables, thus allowing the flow of more active power through the system and avoiding over voltages. Shunt Reactors can be directly connected to the power line or to a tertiary winding of a three-winding power or distribution transformer.

Differential Voltage Probes
DP150/DP200pro
-
The DP differential isolation probes are an important accessory for any laboratory involved in power electronics and high voltage systems. These probes allow isolated and floating measurements with any oscilloscope or data recorder, whilst the oscilloscope can remain grounded. Using a DP150 or DP200pro probe, differential and floating measurements can be made on a variety of ac power systems like 230V/110V ac input power supplies, chopped and switching power supplies, thyristor controllers, variable speed motor drives (PWM signals), motor inrush current and measurement across current shunts. The isolated input is made via two 4mm/banana safety sockets. The BNC output allows easy connection to an oscilloscope. The DP probes can be powered from a 9V battery or external power supply.

50 Pin Breakout Interface
VSI-Breakout-50
-
The VSI-Breakout-50 is a very useful tool in debugging signals or software in a system. It allows unlimited access to signals within the cabling that might otherwise be difficult to access. The board gives test points at each side of the connector and jumper with a easy to use tabbed shunt to allow for easy disconnection of any particular signal between the connectors. The jumpers also give an opportunity to inject a signal regardless of what signal was originally being driven.

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.

SparkFun Current Sensor Breakout
INA169
-
The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.

The panel switches and adjustment pots are labeled to match the test procedure numbers and the duplicity in marking makes it easier for the technician to understand each function. The UUT interface is through a 96 pin zero insertion force(ZIF) type connector to minimize contact wear. The expanded localizer and nav input pins J2-34/35 are exposed on the panel to facilitate the insertion of a 200 ohm shunt when required. The fixtures rear panel has connectors for the required dual API/Synchro transmitter interface while the panel switches provide the correct routing of each.
