|Multi-tap portable CT test set….by Lithonix Power Inc. for under $10K creates improved competency for testing CT’s for control function or for metering function.. High accuracy of 0.1% with 0.05% typical, fully automatic (2 buttons to push) multi-tap test for ratio and saturation. Accurate power parameter measurements. Several modern ways to extract and report test data. Made in USA. [Click CTMP 2020M brochure].
Watch this demo that shows 2 easy key presses to do full automatic multi tap CT Ratio and Saturation test.
|Ground Grid Integrity test set, Portable and rugged 300Amp current supply to inject 300A at various nodes of the exposed substation ground grid to verify proper grid paths under the surface. Co-developed by a major US utility to inject and be key part of measuring current flow paths thru the grid. Grid deterioration can be caused over time by corrosion, loosening joints, poor installation, poor workmanship, or vibrations (quakes) And oh by the way, this GGT500 is also a very good lightweight 500A micro-ohmmeter for measuring breaker contacts and bus joints.[click for GGT500 pdf].|
|Substation Ground Test system are also offered from Red Phase Instruments. High current sources and Frequency selective meters, to verify the substation’s ground grid overall effectiveness of connecting to true Earth ground.
See attached brochure [click for Red Phase Earth test pdf] on Red Phase products for testing substation grounding to true Earth,,,,not to be confused with above Ground Grid Integrity tester GGT500.
UV Imaging camera for corona detection model UV 260 from Sonel. High sensitivity to UV signals with background noise reduction makes it easy to locate corona emissions. Built in GPS, color screen, fast zoom with auto focus. [Click for brochure UV 260]
|*High end multi-phase relay test sets, DRTS series from ISA, available in 4 configurations (6I-6V, 6I-4V, 3I-4V and 3I-3V) and can provide up to 430VA per current output for each of 6I outputs (see input power supply spec) and all 6I at up to 32Amps per channel. Very high accuracy and ultra-low distortion for hi-res DAC design. Bright front panel display and control makes it useful without PC software. For more complex testing, versatile TDMS software is included with multiple copies and updates being free!|

|*Single phase hi current relay tester model T1000PLUS from ISA can be called the relay engineers toolbox as it is a powerful (Max 200A) single phase source that is very easy to set up and generate signal quickly. Software not required. It can do complex timing measurements plus variable phase and variable frequency via an auxiliary channel to main channel. T1000PLUS [click for T1000PLUS pdf]|
|*Single phase hi current relay tester with differential test built-in, model TD1000PLUS from ISA has same features as T1000PLUS but adds a higher current second channel of current to test differential electro-mechanical relays. TD1000PLUS [click for TD1000PLUS pdf]|
|* CT, VT, PT test set with power, model T2000 and T3000 from ISA, for tap by tap CT testing using current or voltage method. Current method improves test competency. 800A AC and 3000 VAC std and optional 400A DC. Test phase angle, turns ratio, polarity, excitation curve, burden and voltage withstand. Expandable up to 4000A AC with boosters. T3000 includes relay test functions similar to T1000PLUS.|
