SCR ELEKTRONIKS
Dry Arc Resistance Tester is designed to conduct high voltage,low current Arc Resistance test on solid electrical insulation material as per:ASTM standard D495-99 (2004) and UL 746A. Why Arc Resistance Test? Many Cases of insulator failure are due to deterioration of its surface because of sustained electrical discharge or Arc. This test method is intended to test the resistance of insulating material when a high -Voltage low -current Arc close to the surface of insulation, intending to form a conducting path therein or in causing the material to become conducting due to decomposition and erosion.AdvantagesThis Test ensures that your products meet high standards of quality & safety. This product is meant for all Switchgears/ insulator/ Polymer/ electro plastic manufacturers and manufacturers who use insulators in their products e.g. Wiring Accessories, Appliances, HT/LT line insulators etc.

MC142 -
Powertek LLC
Multifunction calibrator MC142 is a precision voltage, current and power calibration source serving as a measurement standard in calibration laboratories and production lines; where verification of electrical measurement equipment & sensors is required. It can be used for calibration and adjustment of meters measuring voltage, current, power, resistance, capacitance and frequency. Internal harmonic and non-harmonic signals make it possible to test electrical performance of meters using signals with various crest factors. Frequency modes enable selection of frequency, amplitude and duty cycle of the output signal. These are suitable for basic calibration of digital and analog oscilloscopes along with transient recorders. The calibrator is equipped to measure temperature with TC and RTD temperature sensors. Its built-in multimeter can be used independently or simultaneously with the calibrator output. Testing of transducers of various types, regulators and sensors can be performed, without the necessity to use any other measuring instrument.

GGT Series -
IBEKO Power AB
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.

Datexel
The DAT4530 can convert any process signal (Thermocouples, RTD, mV, Voltage, mA Resistance and Potentiometer) to a voltage or current output (4-20mA, 0-20mA or 0-10V). Each output can be different and it also has a built in limit alarm which is an SPST relay. The DAT4530 is PC programmable with the aid of the Prodat programmer and the Datasoft software which is available from the Datexel down load page. The DAT4530 is also programmable with the aid of 3 DIP switches which can be found on the side of the DAT4530. There is full isolation between the input, power supply, limit alarm output and two outputs.

Extech 480172 -
Extech Instruments Corporation
This Extech 480172 Line Splitter provides a fast and easy way to “open” standard 120 Volt AC electrical lines, eliminating the need to cut off the plug and separate the conductors. When connected between a 120 Volt AC outlet and a device under test, this splitter separates the hot/live conductor from the neutral and ground, which enables users to measure AC current up to 15 Amp on a two-wire or three-wire lines using a clamp meter. This splitter also features two Voltage Test jacks so that voltage can be measured using a multimeter.
