Circuit Breaker Analyzer
CAT Standard Series
The CAT Standard series circuit breaker analyzers & timers are stand-alone or a PC-controlled digital instruments for circuit breakers condition assessments. The timing channels record closing and opening of the arcing, resistor, and auxiliary contacts. CAT Standard series records graphs of both, trip and close coil currents and displacements of the HV and MV circuit breaker moving parts. The main contact channels can also measure the resistance value of the pre-insertion resistors (if present in the circuit breaker). Test results can be downloaded to a USB memory stick or saved to internal memory. The CAT Standard series internal memory can store up to 500 test results (numerical and graphical data). Test results can also be printed on the 80 mm (3.15 inch) thermal printer (optional accessory) in tabular and graphical form. CAT Standard series provides an easy selection of different operational modes:

High Voltage Divider
HIGHVOLT Prüftechnik Dresden GmbH
Is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them.

MAX31855 T-Type Thermocouple Arduino Shield
SEN-30004-T47
Four channel MAX31855 digital thermocouple Arduino Shield. Two versions of this shield are avaliable for each thermocouple type: either 'Ch 0-3' (CS pins use Uno/Mega IO pins 7-10) or 'Ch 4-7' (CS pins use Uno/Mega IO pins 3-6), with the only difference being which set of zero-ohm resistors are populated on the board. This allows use of other SPI devices that may be 'hard coded' to specific digital pins on the Arduino, or simply stacking one of each type together to get a total of eight thermocouple channels on one Arduino.

Motor Starting & Control Resistors
Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.
