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.
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.
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.
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.
