Reasons Why Transformer Oil Testing Is Important
The powerhouses may be located distant from the load centres, as in hydro powerhouses or the middle of populated regions, as in steam powerhouses. The transmission network is an unavoidable need. Long and high voltage transmission lines are required to transfer large blocks of electricity from generating to load centres, link power-houses for improved supply... Read More
Difference between (CT) Current Transformer and (PT) Potential Transformer
For safety reasons, electrical instruments are not directly connected to high-voltage meters or control apparatus. When connecting electrical instruments to measuring instruments, instrument transformers such as voltage transformers and current transformers are used. These transformers convert high-voltage and high-current instruments to low-voltage and low-current instruments. Current Transformer This device converts higher-valued current to lower-valued current... Read More
Top 5 Benefits of Three Phase Transformer
Three-phase transformers are more cost-effective for delivering massive loads and distributing large amounts of electricity. Even though single-phase transformers link most of the utilization equipment, they are not favored for massive power delivery. Three-phase control is used in almost all electrical power systems, including power storage, transmission, and distribution; all manufacturing industries are either supplied... Read More
How to Choose the Right Insulation Resistance Tester (Megger)
Choosing the best insulation resistance tester to do the job correctly is essential. With so many models on the market, people sometimes get lost in choosing the right one. So, how are you going to pick a suitable insulation tester? To find out the response, it is essential to understand which method of research is... Read More
How to Protect a High Voltage Transformer from Getting Trip?
Problems related to the increase in the transformer temperature above the assumed maximum atmospheric temperature require certain means of protection. Selectivity means that the device must clear any fault of current interruption being the nearest to the fault, even if the fault is detected by other protections associated with other interruption devices. Transformer issues need... Read More
What Is High Voltage Cable Testing?
Cable diagnostic tests are predictive to evaluate a cable’s relative degree of deterioration against the newly created state. The chances are that the cable will work correctly sometime during the lifespan of the cables. Asset managers are expected to determine the ageing and overall state of service-aged cable networks, such as assessing what needs... Read More
What Is HIPOT Testing?
It is essential to test Hipot to ensure that the current flows smoothly from one stage to another. The test verifies the cable’s integrity and its ability to withstand a given amount of electricity at high voltages. Testing guarantees the durability of cable assemblies or wire harnesses, proving life-threatening if a malfunction has occurred. All... Read More
Why Different Kinds of Industries Deserves Different Kinds of Transformers?
A transformer is a remote electrical device that helps in operating the electrical vitality between different circuits. A fluctuating current in the transformer curve provides several different attractive transitions and it also activates a changing electromotive power twisted back to look around the center that is connected. There are different needs and over the transformer... Read More
Ultimate and Comprehensive Guide of Transformer Ratio Testing
A transformer turns ratio is the test taken for the confirmation of the accuracy of the transformer. This test will help in ensuring the correct ratio of both the primary turn and the secondary turns. It can also help in finding some issues regarding the tap-changer performance, incorrect winding connections, shorted turns and open windings.... Read More
What Are The Various Precautionary Steps For Variac Transformer Maintenance?
What is a Variac? A Variac Transformer a transformer that generally has a single winding and a single layer. The top section of the winding is generally flattened and machined. It is done to remove to insulation and provide a smooth surface for the sliding brush that is used to select the required voltage. There... Read More
