A transformer is a device which helps with the transmission of electrical power, it is a static device without any rotating part and is totally enclosed. So the transformer plays a major role in the electrical distribution so the protection of transformers is an important process. The transformer must be protected from faults in order to do effective power distribution. What are the types of transformer faults 1-Over heating Over-heating is caused due to sustained overloads, short circuits and in case of failure of the cooling system, Overexcitation if a transformer is operated at its maximum potential like high frequency or in high voltage the core will get excited. Protection - Resistance temperature indicator can be used near the winding, Thermal overload and temperature relays can be used. Bridge circuits can be used when the bridge is unbalanced more than the permissible duration circuit breaker trips. 2-Winding faults The winding faults are internal faults, over-heating or mechan...

When it comes to power regulation, transformers are everything. Step-up and step-down transformers can boost or lower voltages to apply whatever level of power is necessary for a given application. Transformer noise can be a significant problem. Even small amounts can gum up the works and prevent power transformers from working the way they were designed. It is very important to know exactly what transformer noise is, why it causing it and how to prevent it. What Causes the Humming Noise in an Electrical Transformer? There are actually multiple causes of transformer noise. The main one is the Magnetostriction Effect. This is when the current that flows through the transformer’s coils creates a magnetic field. The magnetic field then changes the dimensions of the transformer’s iron core. The core expands and contracts with the alternating current, which causes a humming sound. As the transformer ages, the layers within the core of the transformer begin to break apart and separate from o...

Transformers are an expensive and important part of any machinery. So for getting optimal performance and increased product life, it is best to conduct regular maintenance checkups on your transformer. There are basically two types of transformer maintenance. One is done on a regular basis and the other is done at the time of urgency.  If maintenance checkups are done on a routine basis then you may not have to undergo breakdown maintenance and hence save downtime. There are a lot of different types of maintenance checks to be conducted on a power transformer. Here are some of the main transformer maintenance actions that have to be performed: Transformer Maintenance Checks on a Monthly Basis: Oil level in the oil cap must be checked on a monthly basis so that it doesn’t drop below a fixed limit and hence avoid damage due to it. Keep the breathing holes in the silica gel breather clean to ensure proper breathing action at all times. If your electrical transformer has oil filling bu...
