To achieve local and international standards, various testing equipment for our range of transformers are available at our factory. All our measuring instruments are calibrated yearly by recognized calibration agencies. Every transformer we produce is tested individually by skilled engineers for its performance prior to arrival on site to ensure successful operation. Standard factory test reports are provided for all manufactured transformers.
Our clients are always welcome and often invited to the Factory Acceptance Test (FAT) at our factory testing facilities. We can also arrange for 3rd-party testing of our products whenever required.
