  Timers for Industrial Electrical Panels

  A timer consists of a set of switches with open and closed contacts. It works by receiving electrical current, and based on its settings, it will change the state of its internal contacts after a specified time. These timers are used to start automatic devices or initiate industrial processes. There are two types of timers: analog and digital.

  • Analog Timer: This type does not display elapsed time but shows the timer’s status via a marker.
  • Digital Timer: This type allows you to see the set time and the elapsed time. Digital timers are more accurate than analog ones.

  Common industrial timers include:

  • Clockwise/Counterclockwise Timer: Used for rotating motors in either direction.
  • Restart Timer: Used as a protective timer with a delay before reconnecting and operates for a short time.
  • Star-Delta Timer: Used for motor startup and converting star to delta.
  • Command Hour Timer: Used for tasks at regular intervals, such as daily, weekly, or monthly.
  • Multipurpose Timers: Used for situations not covered by the above timers.

  Terminal Blocks

  The primary function of terminal blocks in industrial electrical panels is to connect wires in a standardized manner. Using terminals ensures a safe connection, preventing overheating and fire risks that might occur with tape. The main types include rail-mounted terminals, fork-type terminals, and screw-type terminals.

  • Rail-mounted Terminal: Installed on rails inside the panel for branching wires.
  • Fork-type Terminal: Used for creating strong and standard connections between two wires.
  • Screw-type Terminal: Used to connect wires without terminal caps, providing a strong connection.

  Busbar and Insulator

  The busbar is a metal strip used to connect high and low-voltage equipment in electrical panels. Busbars distribute phase power within the panel, with types such as earthing busbar and neutral busbar. Insulators are used to insulate parts and prevent contact with the panel’s body. They are typically made from ceramic materials with high electrical and mechanical resistance.

• Troubleshooting Industrial Electrical Panels

  Troubleshooting electrical panels is an important issue for electrical engineers in industrial units, and having knowledge of how to troubleshoot them is an essential part of their job. A malfunctioning electrical panel in a factory or industrial unit can cause production line stoppage, leading to significant losses for the company. Therefore, it is crucial for engineers and operators of electrical panels to have sufficient knowledge of troubleshooting.

  In the event of a problem with the electrical panel, before paying attention to other factors, it is advisable to first check the main switch of the panel. If you notice that the MCCB switch is in the middle position, it means that the main switch is in a fault condition. To fix this fault, you must first determine the cause of the fault. Potential causes of the fault include:

  • Short circuit
  • Damage to the switch
  • Overload
  • Faulty auxiliary contacts inside the switch

  In the fault condition, you should not reconnect the switch without following proper safety procedures. To do so, first disconnect the switches and fuses to remove the load from the switches, then follow these steps:

  • To ensure that the fuses and switches are properly connected, check the busbar connections.
  • Check the main switch for proper functioning. Use a multimeter to measure the voltage difference between all phases at the input of the switch. Under normal conditions, they should all be the same.
  • Check all input and output connections of the switch. This includes both internal and external connections.

  After you have checked all the above, and while observing all safety precautions (wearing proper clothing, shoes, and insulated gloves), and with the switch and fuses completely disconnected, you can reconnect the switch.

  Next, check the operation of the auxiliary switches and fuses. (This step is very critical, and if an untrained person is careless, there is a high risk of personal injury.) If the auxiliary switches and fuses are working correctly, then there is no issue.

  However, if there is a problem with one of the fuses, you should check the output connections and quickly find the cause of the overcurrent. It is essential to have a complete understanding of all the components of the electrical panel and their assembly and operational methods.

  Therefore, it is very important to be able to identify the function of each component if several contactors or other devices are used in an electrical panel. Phase control is one of the essential components in electrical panels, which is sometimes found to be missing. Prioritize checking the phase control.

  You should also check if a fault has occurred. Faults usually happen due to overcurrent, phase displacement, or even a two-phase condition. Then, check other measuring equipment. For example, check the load controls that can detect overcurrent in the circuit via the CT3, and the circuit will enter fault mode, causing the current to be cut off.

  If no fault has occurred but the control circuit is not functioning, you should check the power supply to the control circuit fuse to ensure it has not been damaged or burned out. Additionally, components like the start and stop buttons, mushroom stop button, selectors, auxiliary contacts of the contactors, and the correct supply to the contactors must also be checked.

  In some cases, the issue is not with the electrical panel itself, and the problem may lie elsewhere. For example, if the electrical panel is programmed to activate a fuse after starting and the motor has been cut off by the circuit, you need to check the motor and troubleshoot from there.

  Start by disconnecting the motor cables from the output terminal and try starting the panel without the motor. If the panel starts without issue and stays connected, it indicates that the motor is faulty, and it may have a locked rotor. You should apply this approach to other cases as well.

  Industrial Electrical Panel Price

  Several factors affect the cost of an electrical panel. These include the material of the enclosure, which can be metal or plastic. The metal type may be iron or stainless steel, and the plastic type can be either plain or transparent. The size and volume of the enclosure must also be considered.

  Additionally, the equipment and components used in the panel, the brand of equipment, and the design voltage also affect the price. Each of these factors contributes to the final cost.
