DV-Power-RMO-TT PENGUJIAN TEMPERATURE RISE TRANSFORMATOR 3 PHASA-Heat Run Test

May 10, 2021May 10, 2021 bdmandiri0 comment

ABSTRAK Panas merupakan salah satu penyebab menurunnya ketahanan isolasi trans-formator, padahal tipe isolasi transformator mempunyai tingkat ketahanan terhadap suhu yang berbeda-beda. Tujuan pengujian kenaikan suhu adalah untuk mengetahui kenaikan suhu minyak dan belitan transformator. Pengujian menggunakan metode “HEAT RUN.” Salah satu fitur yang disediakan oleh Software DV-Win adalah mode uji Heat Run otomatis. Instrumen melakukan pengukuran resistensi berliku / winding resistance. Instrumen perlu dihubungkan ke Trafo Winding secepat mungkin setelah transformator dimatikan/ Off-Line. Metode ini memastikan bahwa hasil interpolasi yang paling akurat akan diperoleh. Saluran pengukuran resistensi 1 (VS_1) digunakan…

DV-Power – Handheld Circuit Breaker Analyzer & Timer CAT-H

April 27, 2021April 27, 2021 bdmandiri0 comment

Handheld Circuit Breaker Analyzer & Timer CATH is a digital instrument for circuit breakers condition assessment. CAT-H records graphs of both, open and close coil currents, timing of main arcing contacts, DC substation battery voltage.The timing channels record closing and opening of the main contacts and can also measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).CAT-H provides an easy selection of different operating modes: Open (O) Close (C) Trip free (CO) Reclose (O-C) Close-Open (C-O) Open-Close-Open (O-C-O)Multiple operations, such as Open-Close and Open-Close-Open, can…
