The DELTA4000 series tests electrical insulation in power apparatus The DELTA4000 series is an automatic 12 kV insulation power factor/tan delta test set for assessing the condition of electrical insulation. The DELTA4000 is an automatic 12 kV insulation power factor/tan delta test set designed for the immediate condition assessment of electrical insulation. In addition to traditional power frequency (50/60 Hz) testing, the DELTA4000 uses 1 Hz power factor/tan delta to enhance power frequency assessment of high voltage transformers, bushings, circuit breakers, cables, lightning arresters, and rotating machines. Using the same connection and software as power frequency tests, 1 Hz improves maintenance planning by reducing the need for historical trending and proprietary databases. The high power variable frequency design generates its own test signal independent of line frequency quality, and the hardware design uses the latest technology available for digital filtering of the response signal. As a result, the DELTA4000 series produces reliable results and stable readings in the shortest time with the highest accuracy, even in high interference substations. The DELTA4000 series operates with PowerDB software for automatic testing and reporting or with Delta Control software for real-time manual testing. Measurements include voltage, current, power (loss), power factor/tan delta, inductance, power factor, and capacitance. The test results are automatically stored in the computer and can also be downloaded directly to a USB drive or a printer.
