Just a Fluke: 1740 Series Three­Phase Power Quality Loggers


The compact Fluke 1740 Series Power Quality Loggers are used for studying and monitoring utility power quality and demand to industry stan- dards. They offer advanced data aggregation and analysis that saves time, reduces manpower, and eliminates errors associated with traditional data collection and reporting. The Fluke 1740 series log-


gers are fully compliant with the international power quality standard IEC 61000-4-30 and meet Class A requirements. They are capable of simultane- ously logging more than 500 parameters for each averaging period, allowing technicians to to identify the root cause of disturbances. www.fluke.com


EM330 3­phase Energy Analyser With 5A CT Connection From Carlo Gavazzi


Carlo Gavazzi introduces the EM330 3-phase energy meter with 5A CT input. As with all meters in EM300 Series, the EM330 utilises touch screen technology making standard user operations such as page scrolling, programming and parameter checks not only simpler but faster; as well as, easier to read avoiding any mechanical issues normally associated with using traditional keypads. EM340 is housed in a 3-DIN module and offers outstanding ease of use, performance and measuring of imported and exported energy. The EM330 3-phase energy meter with 3x8 digit backlit LCD data display and integrated touch keypad; suited to active energy metering, cost allocation and dual tariff management. The meter is optionally provided with pulse output as an alternative to the serial communication via RS485 Modbus port or M-bus output. A selection of variables can be programmed


providing for active and reactive energy measurement, options include: system variables such as kW, kvar, kVA, VLL, VLN, PF, Hz, kWdmd, kWdmd peak; phase variables including kW, kvar, kVA, VLN, A, PF. Energy measurement: kWh and kvarh (imported/ exported); kWh+ by 2 tariffs; kWh per phase.


Instantaneous variables are displayed as 3 x 4 digits, with energy meter readings to 8 digits. Accuracy is ±0.5% RDG (V, A), and the meter is rated Class B (kWh) accord- ing to EN50470-3 and Class 1 (kWh) of EN62053-21. The EM300 series of meters


are also available as MID certified. The European Union’s Measuring Instruments Directive (MID) is designed to guarantee the accuracy and reliability of meters. www.carlogavazzi.co.uk


Megger’s improved & popular all­in­one EZ­THUMP™ unit


D


etecting faults on underground MV power cables has been made easier than ever, thanks to the introduction of a new and


enhanced version of Megger’s popular all-in-one EZ-THUMP™ cable fault location system. Designed specifically to be readily transportable – it will fit into


an average-sized car – and is said to be easy to operate, even for inexperienced users. The EZ-THUMP V2 is an ideal choice for first responders, but its extensive capabilities mean that it is also well suited to more demanding applications. The EZ-THUMP V2 incorporates a single-stage capacitor surge


discharge system that delivers 500 J at 12 kV. This is partnered by an integrated time-domain reflectometer (TDR), which facilitates pre- location of low-resistance faults and, by using the arc-reflection method (ARM), high-resistance faults. In addition, the EZ-THUMP V2 can be used in conjunction with


an acoustic/electromagnetic receiver to pinpoint the precise location of faults. Sheath testing and sheath fault location are also supported. Advanced safety features provided by the instrument include the F-OHM system that automatically checks that earth connections have been made correctly and inhibits testing if it detects a problem, and facilities for connecting external safety devices such as warning beacons and emergency stop pushbuttons. All of the instrument’s functions are controlled with a single


rotary knob, and the test results are shown on a high-brightness colour display that is easy to read even in bright sunlight. No settings at all are needed when the instrument is used in automatic mode – users simply connect the test set to the cable and switch it on. The cable end and the fault location are then automatically detected and displayed. More experienced users can access expert mode to optimise results in particularly challenging applications. Light in weight and exceptionally compact, the EZ-THUMP V2


Asset Optimization Software to support Digital Transformation for power utilities is now available from ABB


ABB has announced the global launch of its new ABB Ability™ Ellipse software solution delivering a cross-enterprise approach to connected asset lifecycle management. The comprehensive solution suite will enable electric power utilities to optimize asset utilization, drive down maintenance costs and reduce equipment failures and system outages. Electric utilities are increasingly challenged to maintain high asset availability, performance and reliability against the backdrop of aging infrastructure and financial pressures. In addition, the number of new assets entering the grid is exploding – from smart meters and switches, to distributed energy sources such as solar and wind, to electric-vehicle charging stations. Meanwhile as grid complexity grows, utilities


face rising customer expectations and new regulations requiring higher levels of service reliability and improved product resilience. “We understand the challenges electric utilities face in driving greater levels of performance in an increasingly complex grid” reports Massimo Danieli, head of ABB’s Grid Automation business within the company’s Power Grids division. “With ABB Ability Ellipse, utilities can now use a single, streamlined solution for the management, maintenance and monitoring of assets enabling a stronger, smarter and greener grid.“ The new ABB Ability Ellipse solution offers utilities a proactive approach for predictive maintenance


that combines an asset management system with collection and analysis of performance data and a comprehensive workforce management solution for dispatching crews and maintaining critical assets. Specifically, the solution unifies the functionality of ABB’s world-class solutions for Enterprise Asset Management (EAM), Workforce Management (WFM) and Asset Performance Management (APM). “The biggest risk utilities face on the journey to digital transformation is the inability to unify applications and data,” Kevin Prouty, Vice President IDC Energy Insights, tells UKPN. “One of the most obvious starting points for utilities is to address the silo approach to asset management and workforce management in their organizations. As Asset Performance Management becomes a focal point for transforming the modern grid, it is vitally important that utilities manage their assets and labour with a cohesive strategy.” new.abb.com/uk

can be powered either from an AC mains supply or from its own internal rechargeable battery. These features mean that it can be used in any location, even where access is difficult and no mains supply is available. The internal battery is designed to have a long operating life but, when replacement eventually becomes necessary, this can be done in the field by the user. www.megger.com
