Test & Measurement
July 23, 2013 - When a voltage problem is suspected as a cause of equipment failure, Ideal Industries suggests using its VPM voltage performance monitor, which works at the point where equipment is connected. The VPM offers real-time monitoring of TRMS voltage, frequency and harmonics. Once plugged into an outlet, it will measure, categorize and list each voltage event, including its magnitude, duration and exact time of occurrence. With this information, the technician can identify whether voltage is the cause of the equipment failure or some other issue exists. Up to 512 events can be logged onto the VPM for analysis. The VPM can also be used to determine whether voltage is stable enough to connect additional equipment to a circuit, or if power conditioners—such as a UPS or surge protector—are required.
July 23, 2013 - T3 Innovation is now shipping its dual-mode Arc Chaser cable tester and TDR, which is capable of finding faults (e.g. opens, shorts, arc faults) on energized cables up to 600V up to 12,000 feet. It can monitor live cables for intermittent conditions, capturing these events and reporting where and when they occur. Using Spread Spectrum Time Domain Reflectometry (SSTDR), Arc Chaser promises accuracy to better than 1%. Arc Chaser features a colour, touchscreen that displays results in graphical or text format, and saves reports saves reports that can be transferred to PCs. The unit self-calibrates, says T3, and provides imperial or metric measurements.
July 9, 2013 - Megger now offers four “enhanced” 4-terminal earth/ground resistance and soil resistivity testers promising greater testing flexibility: the DET4 series. The DET4TC2 and DET4TCR2 include ART (attached rod technique) capability that is already included in Megger’s DET3TC, as well as stakeless (clamp-on) testing for applications where traditional fall-of-potential testing is not possible. ART testing allows onsite grounds to be tested separately without having to remove the utility connection. Stakeless testing allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate a fall-of- potential tester when necessary. All four models offer selectable output voltage of 25V and 50V, and are rated to 100V Cat IV. DET4TC2 and DET4TCR2 have a resistance measurement range up to 200,000 ohms, while the DET4TD2 and DET4TR2 have a resistance measurement range up to 20,000 ohms. All of the units are IP54-rated and are designed to meet safety standards.
June 20, 2013 - EA Technology has launched an instrument for identifying defects in live cables of distribution voltages. The CableData Collector tests for Partial Discharge (PD) activity in live cables by measuring radio frequency currents. It works with most types of single and three phase insulated cables at distribution voltages, up to several miles/kilometres in length. Information about PD activity is recorded by the CableData Collector hardware and can be sent to EA Technology for analysis. Alternatively, users can buy EA Technology’s software package to perform their own data analysis.

Updated electronics also reduce unit power consumption and increase battery life, says Greenlee.
May 31, 2013 - Megger now offers a handheld, high current micro-ohmmeter that delivers up to 240A of current, ideal for testing busbar and cable joints as well as carrying out contact resistance measurements on low-, medium- and high-voltage circuit breakers. The MOM2 features DualGround testing for circuit breakers, allowing both sides of a circuit breaker to be earthed while testing and eliminating potential hazards from induced voltages. The tool’s rechargeable batteries permits use in the field where no power supply is available. The instrument can store up to 190 test values and transfer test data to a PC via Bluetooth.
May 16, 2013 - Megger says its new KC series of test leads are long enough to be used for assessing the continuity of lightning protection conductors in wind turbine blades. Developed and designed in conjunction with wind turbine manufacturers, the KC series is the first commercially available product of its kind to have been specifically designed for wind turbine applications, boasts Megger. The leads promise accurate results and eliminate the time-consuming, inconvenient and unreliable process of engineers and technicians fabricating their own test leads, adds Megger. Available in three lengths (328 ft, 164 ft and 98 ft), the KC series can be used onsite or in a manufacturing plant; each lead comes standard on a heavy-duty cable reel that is fitted with a friction brake to avoid tangles when reeling out the cable.

Cable Prowler measures cable length (using TDR technology) and generates tone levels for signal tracing and cable identification on all pairs, a selected pair or a selected pin. All of this displayed in a full colour graphical display. Cable results can be exported to a computer via micro USB cable for record keeping and printing.
May 13, 2013 - Klein Tools expanded its test & measurement line with “Made in the USA” multimeters and receptacle testers promising higher durability and superior quality (see photos below). The meters are built to endure a 10-ft drop and include a raised rubber boot for increased display protection. They also feature improved accuracy, says Klein, and an easy-to-access fuse and battery compartment. The upgraded receptacle testers can withstand a 6-ft drop and include a new design that reinforces the prongs. The MM5000 and MM6000 True RMS meters have increased DC accuracy of ±0.3% and ±0.2%, respectively. They include a low impedance setting to eliminate ghost voltages as well as a µA setting for checking flame sensors. The RT500 and RT600 receptacle testers are designed to detect the most common wiring problems in standard 120V receptacles. These products test for correct wiring, open ground, reverse polarity, open hot, open neutral, and hot and ground reversed. The RT600 also tests GFCI receptacles for proper operation.
April 19, 2013 - Megger offers a hand-held TDR (time domain reflectometer) featuring a 2ns pulse width that, says the company, virtually eliminates dead zones, locating faults less than 3 ft from the point of connection. Designed for use by linemen in the communication and power industries on all metallic pairs, including twisted pair copper and coax, the CFL510G is suitable for CATV/cellular, power and telephony applications. Incorporated into the CFL510G is an auto set-up feature that determines the impedance of the cable under test, sets the instrument accordingly and selects the optimum gain and pulse width chosen by the operator. A large, high-resolution backlit display comes standard, and the unit features four output impedances, and a velocity factor between 0.20 and 0.99. The IP54-rated CFL510G is lightweight, powered by AA batteries and comes standard with a three-year warranty.
April 2, 2013 - Ideal Industries—a manufacturer and supplier of tools, connectors and testing products for the electrical and datacom trades—introduced its next-generation SureTrace circuit tracer, which helps electricians locate wires or cables behind walls, pinpoint opens/shorts, and identify fuses and breakers on both energized and de-energized circuits from 0-600V AC/DC. SureTrace circuit tracers have four defined ranges that allow you to select the proper sensitivity for a specific job. Rather than blinking lights and beeps, its display provides a numeric value between 0 and 99, and a variable pitch/tone audible indication as fast-response tracing feedback, while its peak detector instantaneously registers signal strength. Another time-saving advantage, says Ideal, is that handset signal communication is tuned tighter to reduce false signalling on noisy circuits.
