Megger Delta4000: How to Perform a Power Factor Test using NBDFR and ITC

This video is a detailed walkthrough of how to perform a power factor test using the Narrow Band Dielectric Frequency Response (NBDFR) and Individual Temperature Correction (ITC) functions of the Megger Delta4000 and the PowerDB Two-Winding Transformer Power Factor Test Form (Form 93500). These unique features add significantly more data to your typical power factor measurement.
The DELTA4000 Series is a fully automatic 12 kV insulation power factor/dissipation factor (tan∂) test set designed for condition assessment of electrical insulation in high voltage apparatus such as transformers, bushings, circuit breakers, cables, lightning arresters and rotating machinery. In addition to performing insulation power factor tests, the DELTA4000 Series can be used to measure the excitation current of transformer windings as well as to perform automatic tip-up tests and HV turns-ratio testing (an optional TTR capacitor is available).
Megger PowerDB is a powerful software package providing data management for each of your acceptance and maintenance testing jobs. It controls a vast variety of Megger electrical test sets and effectively manages the data accumulated during testing. Customer and contract information is quickly sorted and searched. Opening a specific record shows detailed information about the job, such as type of service, order date, sales contact, and invoice information. Job information and related test results can be transferred between field-use databases and a master database. Job and Device Productivity Reports track the time spent testing, which aids in bidding future jobs as well as personnel evaluation.
