This is what was found... Published: 23 July 2021 Download PDF Case study: True dynamic resistance measurement Pinpointing concealed problems inside a resistive-type OLTC before physical inspection - the application of true DRM.A maintenance team at the Electric Power Transmission Network in the City of Karbala performed routine electrical tests on a transformer including: winding resistance measurements (WRM), transformer turns ratio (TTR), short circuit impedance (SCI), excitation current, and line-frequency power factor (a.k.a. dissipation factor or tan delta). This case study looks into their investigations and their results. Published: 15 June 2021 Download PDF Case study: Identifying aging and installation issues in an HV bushing The subject 69 kV bushings are installed on a 10 MVA, 69/13.09 kV Dyn1 two-winding transformer. After completing on-load tap changer (OLTC) maintenance on this 1969-vintage transformer, the utility owner followed with electrical tests. Published: 30 April 2021 Download PDF Case study: BSES Rajdhani Power India Electrical maintenance departments are often faced with the challenge of performing different tests on instrument transformers according to official standards and within a limited shutdown time. This is made even more difficult when multiple instruments are needed to perform all the required tests.
