SF6 Optical Gas Imaging Camera
FLIR GF306
The FLIR GF306 optical gas imaging camera visualizes sulfur hexafluoride (SF6) and other gas emissions without the need to shut down operations. SF6 is used in the electric power industry as an insulator and quenching medium for gas-insulated substations and circuit breakers. The portable, non-contact GF306 allows you to quickly scan substations for leaks while maintaining a safe distance from high-voltage equipment. By catching leaks early, the GF306 reduces lost revenue to breakdowns and repairs.

Loop Resistance Measuring Device According to DIN EN 61557-3 (VDE 0413-3)
PeakTech Prüf- und Messtechnik GmbH
A loop tester which is used to test the safety of electrical systems. These device measures the impedance of the short-circuit loop between the outer conductors of a circuit, whereby the probable short-circuit current is calculated. The protection of the circuit (miniature circuit breaker) must therefore trigger at a lower current than the expected short-circuit current, in order to avoid excessive heating of the lines and thus a fire risk. The PeakTech 2715 is due to its function and its robust design almost indispensable when performing new installations, but also for general checking of electrical systems, this device is the ideal companion.

Auto Reclose and Sync Check
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.

Ground Grid Tester
GGT Series
The GGT500 ground grid integrity tester is designed for inspection of the substation ground grid. It can also be used as a portable micro-ohmmeter with Both Sides Grounded and Remote Control functionalities. It is intended to inspection the conditions of a grounding system beneath substations, testing of medium- and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links.In the United States when inspecting the quality of the grounding systems beneath a substation, the proper procedure is to inject 300 A DC during a time period of 60 s. This is what the GGT500 will do, and in that time period, the current path and voltage drop are checked. Also acting as a micro-ohmmeter, the GGT500 can test low resistance values by producing high test currents of up to 500 A.The instrument is placed in an unbreakable, plastic case with IP67 protective rating (with closed lid). Although very portable and lightweight, micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents, as well as the use of thinner/longer test cables. GGT500 ground grid integrity tester generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. This significantly decreases magnetic transients and ensures great accuracy.When used for testing in Both Sides Grounded conditions, a special current clamp powered from the ground grid integrity tester is used for measuring a current through groundings. If even a higher safety level is required, the remote control feature enables the operator to perform measurements from a distant location, away from the instrument and test object.

Multiple Channel Burn In Power Supply
MCPS
The most important features of this burn in power supply is its ability to hold a constant output for each channel even in the event that a unit under test on one channel may short and fail. Since each channel has it''s own transformer, no glitches or voltage spikes can get into any of the other channels. This image shows the results as the second channel from the left is shorted with a small wire and the circuit breaker pops out. Used for burn-in testing and other timed testing where power isolation is required. Very basic simple circuit, see schematic below. Cleans and frees up benchtops, burn in racks and work space clutter. Available in benchtop or rackmount.
