Motor failures

The Hindu 3Presses at Hyderabad, Chennai, Meramalainagar

2004 -2006, Repeat jobs.

Three printing news paper presses at Hyderabad, Chennai at Meramalainagar. To eliminate frequent tripping and electronics failures with Mitsubishi supplier fully automatic printing press systems which extensively used VFD and DC Drives,
Supplied six sets Tuned Harmonic Filters for transformer capacity of between 1600 to 2500kva sizes. Limited harmonic distortions and resolved tripping and failure issues for electronics, motors, capacitors, Switchgear and cable overheating.

Comprehensive Power Quality Analysis

Power Quality Analysis

Abstract: Large continuous process plants are increasingly resorting to use of non linear loads (NLL) such as DC drives, variable speed AC drives, UPS, increased electronic controls etc. to improve performance and productivity of their plants. The plant engineers are increasingly facing unfamiliar problems related to power quality (PQ) mainly problem of distortion of fundamental wave shape and associated effects.
