Modular hybrid motor starters available from Phoenix Contact With Contactron pro,


Phoenix Contact provides a new version of Contactron hybrid motor starters. The new devices have an


additional simple safety integration and modular exten- sion option. The upstream safety relay


guarantees a secure stop of the connected motors after an emergency stop up to performance level PLe. Using the DIN rail connector,


you can perform an emergency stop group shutdown of all the downstream hybrid motor starters without the need for additional wiring. In addition, all modules can


be supplied from the system power supply. The optional response module allows for monitoring the motor status from the control room. www.phoenixcontact.com


Next-generation AVO800 Digital Multimeters now available from Megger


Megger has launched its new series of next-genera- tion AVO800 multimeters. Designed to provide electri- cal contractors and field service technicians with best- in-class level of data & results validity, they also provide a comprehensive host of new and advanced product features. In line with the company’s


focus on creating easy-to-use and safe portable test solu- tions, Megger’s two newly released units – the AVO830 and the AVO835 – combine the renowned build and performance of the historical AVO units with new, proprietary technologies such as simultaneous AC&DC voltage measurements, smart capacity discharge function and non-contact detection of live circuits and conductors. “We are excited to bring to


market two state-pf-the-art product solutions to truly help our customers make vital decisions about their most important assets with peace of mind, which adds complementary value to our new AVO800 series and


Air in-leak monitoring for steam turbine condensers yields dramatic cost saving plus improved performance INTEK, the developer and manufacturer of


RheoVac® line flow instruments for liquid and gas flow monitoring, now offers the RheoVac® Sentry Monitoring System for real-time, multi-point monitoring of condenser air in-leakage within steam turbine power plants. Excess air in-leakage is a problem which can cost


the power generation industry millions of pounds each year. Determining vacuum quality and the overall health of turbine condenser exhausters can benefit users with huge savings through load optimisation. Further benefits can be realized through minimising forced power outages, and the systematic capability of providing organization-wide predictive maintenance and control. Additionally, accurate air in-leakage and dissolved oxygen measurement correlation's mean reduced corrosion, chemical treatment and maintenance costs. The real time data provided by the RheoVac Sentry system allows plant personnel to easily determine if air in-leakage, degraded exhauster equipment, or fouled condenser tubing is the cause of excess back pressure. "With power shortages nationwide and electricity prices increasing exponentially, the combination of


added fuel costs and power generation losses can add up to millions of dollars very quickly," explains Bob Curry, INTEK Marketing Manager. "Amid such rising costs, it is possible for users of the RheoVac technology to realize the return on their investment in a very short time." Based on INTEK's proven single-probe RheoVac Monitoring Technology, the new Sentry system


enables users of large steam power generation equipment to maximise turbine efficiency by providing probes at multiple points to monitor condenser and exhauster performance. Having multiple sensing points on an extensive condenser vacuum system allows for greater detail in system analysis. This in turn dramatically reduces air-in leakage search times while individual pump problems are readily identified and system validation remains continuous. INTEK customers report significant cost savings from having the RheoVac information available to


diagnose and troubleshoot any condenser performance problem. While not a cure for inevitable air in-leakage problems, continuous monitoring through the RheoVac


system detects air in-leakage before excess turbine back pressures occur, warning the user to make necessary corrections and thereby avoid cost penalties which can vary by plant based on size, age, heat rate, fuel costs, and geographical location. EPRI research shows that a single 400 MW unit can easily waste $125,000 (£158,000) annually for each 0.1" HgA increase in back pressure caused by air in-leakage.www.intekflow.com

testing to the next level once more,” Simon Wood, European Distribution Manager at Megger, tells UKPN. As Megger remains


devoted to safe working conditions, the new AVO800 instruments have the highest level of protection in the industry – CAT IV & CAT III 1000 V rating. In addition, a phase-


sequence indication function proves invaluable on three- phase systems, ensuring the correct run of operations without the needs of additional test leads or probes. For more information or enquiries about Megger’s new AVO800 series please visit: www.uk.megger.com

this new model series offers more power for less space, by delivering a much higher power density and a more reliable power solution. Available from 360-450kVA at 50Hz, the new C400D5 and


C450D5 generator set models are powered by a Cummins 4-cycle, inline, 6-cylinder dual speed engine. The Cummins heavy duty engine is designed to respond to low emissions requirements and delivers fast response to load changes, while using less fuel. In particular, an XPI fuel system is embedded on the engine across all new models for greater fuel efficiency. This series is designed for a wide variety of applications to meet


diverse customer needs in different markets such as hospitals, manufacturing, commercial and industrial facilities. The reduced noise level down to 67Db(A) at 75% makes the series an ideal choice for such industries. All new models, can run in grid parallel mode to fit the diverse


project site customer requirements. Additional features offered within this new product offering include extended service intervals of 500hrs for easier maintenance and unaided cold start capability at -12°C. “This product series includes many design and performance improvements and it is a definitive step forward for us. In addition


to the robust performance and fuel efficiency offering, Cummins customers can depend on comprehensive warranty and worldwide distributor network, making this series a perfect fit for global standby and prime power applications,” said Ignacio González, Executive Director of Power Systems Greater Europe. www.cummins.com
