Portable stand-alone cable fault location unit for LV cable installations

• Toolbox philosophy: Identification, prelocation, pinpointing and conversion of faults all in one unit
• Safety interlocks for monitoring of station earth and touch potentials (F-U), as well as earth connections (F-Ohm)
• Fully automatic operation of all modes via motorised switching
• Software-based user interface with single “turn & click” rotary knob control
• ICEplus transient prelocation method for normal unbranched LV cables as well as for branched LV networks
• DC test (DC hi-pot) and burning up to 5 kV, surging (thumping) up to 4 kV, delivers 1000 J

The SPG5-1000-1 is a comprehensive all-in-one-box fault locating solution, tailored for testing, identifying, converting, prelocating, and pinpointing faults in low-voltage cable installations. It effectively handles a wide variety of cable faults: from flashing and non-flashing to high and low resistance, intermittent, main insulation, and sheath faults.

Prioritising user convenience, the SPG5-1000-1 is fully automated and features an intuitive software interface, eliminating most user interventions known from manual analogue instruments. The controller actuates motorised switches so that the unit auto-adjusts to the correct settings based on user input. Simplifying the operation further, a single “turn and click” rotary knob ensures easy accessibility for users of all experience levels.

Utilising the integrated ICEplus method for HV prelocation, the SPG5-1000-1 accurately and precisely locates faults in both unbranched point-to-point low-voltage cables and branched low-voltage networks with T- or Y-joints. ICEplus is a transient prelocation method that evaluates the oscillating current component of a propagating travelling wave which was previously created by capacitor discharge into the cable. Notably, unlike TDR and ARM, this method is unaffected by common issues of attenuation and reflections at T- or Y-junctions, ensuring consistent prelocation regardless of the network’s configuration.

Smart Grid medium voltage sensors for overhead line networks (4 to140 kV)

The MS5000 (Metrysense5000) Smart Grid medium voltage sensor for overhead line networks (4 to 140 kV) provides real-time grid information, giving you unprecedented visibility of your distribution grids through the accurate identification of high impedance faults and predictive analytics for deteriorating network components. It has been designed for FLISR (fault location, isolation, and service restoration), grid analytics, power quality, and flow monitoring.

• Reliable online detection of all types of faults
• Reduces the average interruption duration (SAIDI)
• Reducing number of faults by identifying weak spots (SAIFI)
• Powerful cyber security capabilities
• Unique proprietary algorithms to detect high impedance faults with high accuracy
• Power harvesting for line currents as low as 1.5 A
• Radio communication for rural areas with no cellular coverage
• Operates with earthing systems including solid-grounded, floating neutral, SWER, and Petersen coil
• Connection to existing DMS systems
• Provides on-line grid visibility of currents, power flow etc.
• Reduces wildfire risk, increases safety
• Fast and easy installation

PD Detector

The AIAcompact is a portable instrument for in-service acoustic and electric (UHF) partial discharge measurements on high voltage assets such as:

• Gas-insulated switchgears (GIS)
• Gas-insulated lines (GIL)
• Power transformers
• Distribution transformers
• Cable accessories

To be suitable for all these applications, the instrument adapts to a variety of piezoelectric acoustic sensors and pre- processing units. It can be used with acoustic sensors and external ultra high frequency sensors as well as embedded UHF sensors of the tested asset.

Because of its built-in battery and its standalone capability the AIAcompact can even be used for on-site testing in environments where no mains supply is available.

For a convenient remote control of the device, the USB interface allow the connection to a PC or laptop with the optional AIAcompact software installed.

Every AIAcompact comes with a built-in four-channel multiplexer, which allows switching between four input channels. Buttons at the panel of the instrument enable you to directly select one of the four signal sources. As a result, the partial discharge signal and the voltage signal are split and can be selected separately. All settings, e.g., input and display mode, are stored individually for each channel.

Test van for maintenance and diagnostics of power transformers

The Megger transformer test van is a vehicle equipped with a number of instruments for on-site condition assessment of power transformers. The biggest advantage of the van solution compared to separate or multi-functional instruments is its instantaneous readiness to test, quick proceeding to results and clean up at end of testing. All leads are on drums, preconnected to instruments, through automatic switching no need to climb several times. This results in increased productivity, safety and user comfort, considering an air-conditioned office like work environment.

• Routine and advanced diagnostic tests
• Centralized control and reporting
• Two sets of cables (HV&LV) are shared among different instruments
• Automated test circuit arrangement and switching process
• Safe operation and user guidance through the tests
• Easy extraction of mounted instruments for standalone use

Remote Display True RMS AC/DC Clamp Meter with iFlex

Key features

• Wireless technology allows the display to be carried up to 30 ft. away from the point of measurement with measurement accuracy
• A removable magnetic display can be mounted where it is easily seen
• iFlex® Flexible Current Probe expands the measurement range to 2500 A AC
• CAT IV 600 V, CAT III 1000 V

What once took two people, now takes one

Now one technician can do jobs that would otherwise require two people. Clamp the Fluke 381 around a conductor, remove the display, and walk across the room to operate controls or remove protective equipment, all while watching real-time readings.

The iFlex® Flexible Current Probe (included) expands the measurement range to 2500 A AC while providing increased display flexibility. With a cord that runs 6 feet, you can finally measure those tight spaces, awkward-sized conductors, and disorganized wires.

Multi-function Measurement Instrument

The PMM-2 is an ideal instrument for use in general electrical systems maintenance, electrical machine repairs, protective relay testing or in monitoring power at the electrical service entrance. Motor starting currents, voltages, and power can be captured for analysis.

The PMM-2 is designed to perform fast, accurate checking and testing of protective relay and meter installations during their commissioning and in routine maintenance.

For meter installations, unit can be configured to measure phase-to-phase voltage and single-phase current amplitudes and phase angles. Combined with a voltage or current source, the PMM-2 also becomes an excellent tool for testing and calibrating virtually any type of protective relay.
