ISA T 3000 Primary current injection test set in action at a HV switchyard in Indonesia. T 3000 is designed to perform primary tests requested in substations commissioning. It performs different tests and measurements on current transformers, voltage transformers, power transformers, protection relays, energy meters and transducers. ⚡ Learn More https://lnkd.in/g6HXvTgh Erif Triandari #DobleTested #substations #electricalengineering

Primary Current Injection Test for testing accuracy of CT Ratio. Actually, our project is only installing OLS (Over Load Shedding) Relay. but there is only installed 1 core for protection device, and the condition now the CT Protection core has been connected to 2 protection device (LCD and OCR). consider the CT burden, we cant add more device to CT connection. so we split the core. core 1 for LCD core 2 for OCR and OLS from this moment, i try the Primary Injection Test Set from Doble Engineering ISA T 3000. Thanks to PLN UP2B Jatim and PLN ULTG Probolinggo that give me the experience, i usually do secondary injection test, now i have experience to do primary injection, in the middle of HV Switchyard
