Electrical condition monitoring excellence at your fingertips
We supply state-of-the-art testing and monitoring instruments through collaborations with our Global Partners and support them through training, local calibration, and repairs.
Electrical Signature Analysis
Electrical Signature Analysis (also known as ESA or MCSA) is the standard technology for online detection of broken rotor bars, air-gap eccentricity, interturn shorts and mechanical defects in motors by analyzing the current and voltage spectrum. ESA analyzers also provide the capabilities to perform harmonic analysis, estimate motor efficiency and identify load related defects. We offer handheld, portable and continuous monitoring instruments for this application.
Motor Circuit Analysis
Motor Circuit Analysis (MCATM), also called motor circuit evaluation (MCE), is a deenergized test method for evaluating the health of a motor. Initiated from the Motor Control Center (MCC) or directly at the motor itself, this procedure evaluates the entire electrical portion of the motor system, including the connections and cables between the test point and motor.MCA is capable of detecting ground faults, internal winding faults, open connections, rotor faults and contamination.
AT-34 : The AT-34 TM is a mid-range off-line motor tester that includes many of the features of the flagship AT-7 model. It can diagnose ground faults, test stator windings, find induction motor abnormalities and display results all on the screen within minutes.
It enables technicians to efficiently and accurately evaluate motors whether in the field or on the shop floor – improving motor reliability, increasing technician and asset productivity, and reducing energy consumption.
Motor Genie: The MOTOR GENIE® is an entry-level hand-held motor tester that uses patented technology to troubleshoot low-voltage AC induction motors rated less than 1000 V. It is capable of finding winding faults, including coil-to-coil, turn-to-turn and grounded windings. It also measures impedance, phase angle, current/frequency response, phase to phase resistance and insulation-to-ground resistance.
With its advanced features, the MOTOR GENIE® outperforms other traditional meters such as the Megohmmeter, RCL meters and other resistance meters, that only take measurements. It goes beyond measurement capabilities and analyzes the condition of the motor. These conditions are sent to the associated mobile app on the user’s phone or tablet.
Partial Discharge Analysis and Monitors
Partial Discharge is the industry standard for evaluating the insulation condition of all high voltage equipment. We offer a variety of PD test equipment ranging from basic testers to analyzers as well as continuous monitors. These can test cables, motors, generators, switchgear and transformers and detect any incipient defects.
PDS Insight: PDS Insight™ 2 Is a handheld on-line PD detector for condition-based maintenance and substation access safety. It is used to check for insulation degradation in switchgear, transformers and cables. The PDS Insight™ 2 acquires data using TEV, HFCT and ultrasonic sensors, stores it onboard and transfers the data to Windows-based software that can enable asset and substation registration, PD data analysis, benchmarking and trending. Theseeasy to use handheld meters are suitable for rapid preliminary scanning of a large population of assets with a test time of ten seconds per asset.
Kronos Spot Tester : The Kronos® Spot Tester is a 6-channel, synchronous, battery-powered analyzerwith a rugged and compact design optimised for field portability. It is used for in-depth assessment of insulation degradation in rotating machines, cables, transformers and switchgear.The Kronos® Spot Tester is compatible with every single PD sensor, including coupling capacitor, HFCT, TEV, ultrasound, bushing tap adapter and UHF.
Kronos® is the only analyzerin the world that can combine three unique technologies – electrical PD for all assets, acoustic PD for transformer PD localization and MCSA for rotating machines. The Kronos® Ultimate software has advanced denoising capability (event recognition, pulse waveform clustering, etc.), along with automated analysis and machine learning.
Kronos Permanent : The Kronos® Permanent Monitor is designed for 24/7 continuous monitoring of complete electrical networks. It is capable of detecting both intermittent partial discharges (PD) as well as longer-term trend increases in PD activity. The monitoring system provides early warning against MV and HV insulation faults and supports condition-based maintenance schedules, reducing unplanned outages, downtime and maintenance costs.Kronos® features patented technology that enables a motor, its cables and its switchgear to be monitored using sensors installed only at the switchgear, eliminating the need for retrofits and modifications to the existing motor terminals.
With up to 24 channels and synchronous acquisition on six channels, the HVPD Kronos® can be used to monitor multiple assets simultaneously in addition to comparing data from different sensors.Monitors are available approved for installation in hazardous gas zones. ATEX EEX-D IIB T5 IP66 for zones 1 and 2.
Line Impedance Resonance Analyzer (LIRA®)
LIRA is a patented technology from Wirescan, Norway to diagnose degradation as well as determine fault locations in all cables, from LV to EHV. This is It achievedby injecting low voltage; and high frequency signalsinto the cable and performing frequency domain reflectometry.LIRA can be performed both offline and online.
LIRA Acquire: The Acquire is a portable, offline analyzer that uses LIRA technology to diagnose cable condition. It can detect localized defects, overall aging and termination degradation. The LIRA Acquire has a proven track record of testing cables over 100 kms. in length; and has the added benefit of being completely non-destructive (the applied voltage is less than 10 volts) and does not require the cable to be disconnected.
The types of localized defects that it can diagnose include mechanical damage, mechanical stress, water ingress and heat induced oxidation, with an accuracy of better than ± 1 %. LIRA Acquire is widely used for factory quality control, site acceptance testing after laying new cables, condition monitoring of older cables and fault location in failed cables.
Wirescan Digital (by Wirescan, Norway): Wirescan Digital (WD) is a proprietary automated cloud-based cable monitoringsolution.Specialized sensors are permanently installed on cables (upto 33 kV). These, in conjunction with the LIRA data acquisition system send the data to the WD cloud platform, which analyses the data and presents the results in a user-friendly visualization platform on your computer or tablet.
The system is designed to incorporate historical data (if available), reference/benchmark data and any future data for continuous health assessment, comparison, trending, etc. WD uses GPS coordinates and geographic locations for easy pinpointing and visualization, and is an open platform that can also incorporate other measurements such as tan delta, PD, optical TDR, DTS, etc. to provide solid decision support in assessing whether to keep, repair, replace or monitor your cables. Even if a cable should fail for some reason, rapid fault localization and the comprehensive information available will minimize the downtime.
Generator Rotor Shorted Turn Analyzer
Shorted turns in generator rotor windings can contribute to vibration problems due to rotor thermal bending from the uneven heating associated with non-symmetrical dc current flow and watt losses in faulted windings. Shorted turns can also cause unbalanced magnetic flux in the air gap that aggravates vibration problems. Such defects can be easily detected by the Sumatron RSO Analyzer.
