A motor control center operates your electric motors. You can find a solid-state motor controller or overload relays to protect the engine. Furthermore, you’ll discover overload protection relays and a circuit breaker that offers short-circuit protection. Also, disconnecting control switches to isolate the motor circuit. Separate control transformers serve for the three-phase power to move

While using an electrical panel for your home supply, there is a chance of equipment damage. Besides, the problem may lead to excess power usage or catastrophic equipment failure. Hence, the  Electricity at Work Regulation Act 1989. states guidelines to avoid it. Thermography testing,  detection of defects is becoming popular, as the thermal image can

When lightning strikes, it creates a voltage surge. Both cloud-to-cloud lightning and cloud-to-ground lightning can result in voltage surges.  Now, this voltage surge wants to equalize itself as soon as possible, and it can do so by short-circuiting your electrical equipment. For example, it can either directly hit your house or strike on a cable

Nowadays, electronic devices are present everywhere, whether it’s a commercial building or residential spaces. That means circuit breakers, switches, relays, and other electrical connections work around the clock to prevent electrical damage. However,  as long as two conductors are in contact, you can expect some resistance. And too much resistance leads to power outages and

Residual Current Devices or RCDs monitor the flow of current in electrical installation from the main power supply to the circuit. Upon detecting an imbalance current, the switches automatically cut off the current supply, thus preventing the sudden disposal of electricity that may cause electrical shock, serious injuries, or death in some cases. However, you

A power distribution system can experience different types of faults. One such abnormal electrical connection is a ground fault . The most common reason for ground fault is reduced insulation. This could be due to moisture, mechanical stresses, or atmospheric contamination. Potential consequences of ground faults are dangerous. Thus, you must be aware of them.

Whether it is a fastener such as a nut, screw, or electrical equipment such as an electric motor, it needs a force to turn. However, if you fasten the nut too tight, this excessive Torque can lead to stretching and, consequently, breaking bolts. On the other hand, if you provide it with insufficient Torque, it will

The insulation goes via two insulation paths – electrical resistance and capacitance. So, there shouldn’t be much leaking because of the impressive resistance levels. However, the problems occur due to wear and tear. The experts recommend limiting the length of the one-way feeder to 250ft. That’s because the capacitance goes up in long conductors, which

Now we know the reason. About Polarity Test，You all know that in Direct Current or DC, there is a negative terminal and a positive terminal. Here, the charges move from the positive side to the negative side, and thus battery produces an electric current. This negative and positive of terminals is known as electrical polarity. However, in Alternating Current

Insulation Resistance Test Procedure，People use conductors to carry current, so they should have low resistance. However, people use the insulation of conductors to keep it confined to the wires, so it has to have high resistance. As a rule of thumb, you need common test methods to evaluate insulation integrity. Also, cable manufacturers perform Insulation

You come across various electronic devices to save time in your daily routine. To work efficiently, they need enough power. However, more than required can cause wire insulation damage and a short circuit in the machine. Then, what can you do then to balance out voltage fluctuation? Place a Capacitor Bank so they can get

About the megohm test, every electrical system involves the flowing of current through conducting wires. The insulation of wires prevents electric current from flowing in any non-desired places. As a result, the current reaches its desired destination without any leakage.  However, with time, some flaws develop in the insulation. Environmental factors like temperature, humidity, moisture,
