Preventive Transformer Oil Testing

Transformer Explosion Breaking News

Transformers are among the most expensive assets in the power network, representing over half of substation capital cost. In that extremely valuable transformer the cellulose insulation is the one component that will degrade with age and cannot be replaced without considerable cost and loss of service. Of the factors that can degrade the cellulose insulation – moisture, temperature, and oxygen – moisture is the most aggressive combatant.

Excessive moisture and other impurities in the paper and oil can significantly reduce the dielectric strength and the partial discharge inception levels; therefore, it has a profound effect on the aging rate.

Transformer Insulation Paper

To put it simply, moisture and contamination in the transformer’s insulation system cause the molecular chains of the cellulose to decompose, in turn accelerating the aging process of the cellulose
and adversely affecting the tensile strength and dielectric properties of the insulation. The result can be catastrophic, ending in premature failure, with replacement involving a considerable amount of time and expense – vital assets that you cannot afford to waste.

Yet, power utilities across the globe are faced with reductions of capital spending, retirement of experienced personnel, and crippled maintenance budgets. Existing resources must be leveraged to get the most out of assets that are nearing the end of their useful life.

Meeting the growing demands of the grid, while maintaining system reliability with this aging fleet is extremely taxing and uneconomical. Without significant changes in the way the utility operates and cares for its transformers, resources will be lost at exponential rates, but traditional maintenance is reactive rather than proactive.

Transformer Oil Testing

For these reasons, regular transformer oil testing saves real time and money to reduce maintenance, and defers the need for capital expenditures to replace these critical expensive assets in the long term. With this no-risk and cost-efficient procedure you can protect a million-dollar investment and ensure that your power transformers perform to their full potential.

OLT Testers by KEP

The OLT Insulating liquid testers by KEP are designed for measuring the oil dielectric breakdown voltage; the A-Series oil testers are fully automatic, produce accurate testing results, safe for the operator, and comply with the industry’s main standards.

The OLT insulating liquid test sets switch off the voltage feed to the electrodes immediately after the testing is over, which allows for testing dielectric liquids susceptible to disintegration due to arcing caused by a breakdown.

Main features of the KEP oil testers OLT A-Series:

Oil Test Set OLT-100A

Fully automatic operation
Fully compatible with IEC 60156
Preset testing programs for different standards
Built-in printer
PC connectivity
Internal test data storage
Precise direct voltage measurement
True sine high-voltage on electrodes
Oil temperature measurement

SCADA

SCADA merupakan singkatan dari Supervisory Control and Data Acquisitio n. SCADA merupakan sebuah sistem yang mengumpulkan informasi atau data-data dari lapangan dan kemudian mengirimkan-nya ke sebuah komputer pusat yang akan mengatur dan mengontrol data-data tersbut. Sistem SCADA tidak hanya digunakan dalam proses-proses industri, misalnya, pabrik baja, pembangkit dan pendistribusian tenaga listrik (konvensional maupun nuklir), pabrik kimia, tetapi juga pada beberapa fasilitas eksperimen seperti fusi nuklir. Dari sudut pandang SCADA, ukuran pabrik atau sistem proses mulai dar 1.000an hingga 10.000an I/O (luara/masukan), namun saat ini sistem SCADA sudah bisa menangani hingga ratusan ribu I/O. Ada banyak bagian dalam sebuah sistem SCADA. Sebuah sistem SCADA biasanya memiliki perangkat keras sinyal untuk memperoleh dan mengirimkan I/O, kontroler, jaringan, antarmuka pengguna dalam bentuk HMI (Human Machine Interface), piranti komunikasi dan beberapa perangkat lunak pendukung. Semua itu...

Persoalan Pokok pada Pembangkit Tenaga Listrik

Pembangkit listrik yang biasa digunakan pada suatu Sistem Tenaga Listrik (STL) terdiri dari pembangkit listrik tenaga air (Hydro plant atau PLTA) dan unit-unit thermal.Pembangkit-pembangkit itu sekarang ini umumnya sudah berhubungan satu dengan yang lainnya, atau yang sering disebut dengan interkoneksi. Setelah beroperasi dalam waktu tertentu, maka dari pembangkit-pembangkit itu ada yang keluar dari sistem interkoneksi dan hal ini disebabkan karena ada unit pembangkit yang rusak dan tentunya perlu diganti atau diperbaiki, kedua karena ada pembangkit yang istirahat untuk keperluan pemeliharaan. Salah satu contoh rencana pemeliharaan unit pembangkit adalah dengan menggunakan metode Levelized Resh dari Gaever . Namun dalam aplikasinya harus dibagi dalam dua kriteria, yaitu pertama unit pembangkit bisa dikeluarkan tanpa adanya penyesuaian. Kedua unit pembangkit yang dikeluarkan harus diatur dalam kurun waktu yang terbatas. Dengan demikian berarti pada waktu tertentu ada unit pembangkit y...

Ferite Core Transformer

What are Ferrite Core Transformers? The transformer made out of ferrite core is called ferrite core transformer . The ferrite core transformer is used for higher frequency applications.The power transformer is made out of CRGO steel core which operate at 50 or 60 Hz frequency. The transformer operating at higher frequency is designed with a ferrite core. The composition of ferrite core in transformer is iron oxides,combined with nickle, zinc and manganese compounds. These compounds have low coercivity and also called soft ferrites. Advantage of use of Ferrite Core ? A major advantage to a ferrite core is its high electrical resistance to high current. The high resistance to eddy current lead lower eddy current losses over many frequencies. Ferrites have an advantage over other types of magnetic materials due to their high electrical resistivity and low eddy current losses over a wide frequency range. These characteristics, along with high permeability, make ferr...

AIRCRAFT MAINTENANCE ENGINEERING'S APP BY MY INSTITUTION

The purpose of this post is introduce an app which introduced my department in polytechnics and developed by one of my lecturer. For my view of point, the app is mostly introduce about the course. So what about it? Let's take a look... In this post, I will introduce about the contents in the app by the phone screenshot which taken from my phone. I will share the way to get this app and the way to install in the end of this post. OK, let's take a look. First, can you guys and girls saw that is one app which named "DAM Students" in the phone screenshot? That is the app which today I want to introduce about. The icon of the app is the aircraft's model located in our hanger. In the front page of the app, you will see there is a few titles in the contents after you entered to the app. In the next screenshot, I will show the example of the contents of the app. These are the content of the courses... The codes are represent different subject. In the subject, they already...
