Bagaimana cara mendeteksi kerusakan isolasi tanpa mematikan peralatan penting?
Detektor pelepasan parsial daring memungkinkan Anda mendeteksi kerusakan isolasi yang tersembunyi dengan aman. Anda dapat menghindari pemadaman listrik yang merugikan, mendeteksi tegangan dinamis sejak dini, dan melindungi peralatan penting Anda dari kegagalan mendadak.
Apa itu detektor pelepasan parsial?
Detektor pelepasan parsial adalah alat pengujian yang berfungsi untuk mendeteksi percikan listrik berukuran sangat kecil di dalam isolasi tegangan tinggi. Alat ini menggunakan sensor untuk mendeteksi gelombang ultrasonik, tegangan tanah, dan sinyal elektromagnetik.
VLF vs. DC Hipot Testing: Which is Safer?
VLF testing is the only safe way to test modern XLPE power cables. It stops space charge damage, follows IEEE standards, and saves your expensive electrical assets from sudden failure.
What are the Best VLF Hipot Testers in 2026 for Your Buyer’s Guide?
Choosing the right VLF tester requires checking the frequency, matching the cable voltage, and comparing brand data. KVHIPOT gives you the best balance of price, power, and reliable field performance.
How Do You Perform No-Load and Load Tests on Power Transformers During Substation Commissioning?
Substation commissioning is hard work. Bad transformer tests cause huge power failures later. I will show you how to do no-load and load tests the right way. You perform these tests by applying voltage to one winding while keeping the other open or shorted. The no-load test measures core loss by opening the secondary winding. The […]
What is VLF cable testing?
VLF cable testing is a safe and smart choice for your cables. By choosing the correct frequency, you find hidden defects easily and keep your power network running perfectly.
What is the IEEE standard for transformer insulation testing?
Selecting the right parameters for a Transformer Megger Test is not a guessing game; it is a science based on standards and physics.
What is battery test equipment and why do you need it?
Battery test equipment is the insurance policy for your backup power. Whether you use a quick handheld tester for monthly checks or a load bank for annual verification, regular testing ensures your systems stay online when the grid goes down.
Panduan Lengkap Mengenai Rasio Putaran Transformator dan Rasio Arus di Seluruh Tingkat Tegangan
Sifat putaran dan arus transformator di berbagai tingkat tegangan pada dasarnya merupakan hasil dari desain komprehensif berdasarkan hukum induksi elektromagnetik, dengan mempertimbangkan tingkat tegangan, kapasitas nominal, skenario aplikasi, dan persyaratan jaringan listrik. Dari rasio putaran 1:25 di jaringan distribusi tegangan rendah hingga rasio putaran 2:1 di jaringan tegangan ultra-tinggi, variasi pada rasio transformasi secara langsung menentukan jarak, kapasitas, dan efisiensi transmisi daya.
Five Common Problems Found During Circuit Breaker Maintenance
The five most common problems found during circuit breaker maintenance are high contact resistance, failed timing tests, high SF6 gas moisture, slow mechanism operation, and distinguishing between mechanical and electrical faults. Using a systematic checklist helps you diagnose these issues efficiently and safely.
