Motor Manufacturing LEARN MORE
Motor Manufacturing

Motors play a significant role across various industries by converting mechanical energy to electrical energy or facilitating motion. They are utilised in vital applications such as power generation, transportation, and medical equipment, as well as in non-critical applications like household appliances. Within processing industries, motors help control conveyor systems, pumps, compressors, and other equipment. Additionally, motors are employed in robotics for manufacturing, logistics, and healthcare sectors.

Motor failures in critical applications can lead to severe consequences. Consequently, testing is crucial for manufacturers to identify any flaws or malfunctions in the motor's design and production process, allowing them to implement necessary improvements for enhanced reliability. Testing also enables manufacturers to assess and benchmark motor performance under various operating conditions. As such, it is imperative for manufacturers to test their motors, ensuring adherence to quality standards and reliable operation under expected conditions.

Circuit Breaker Manufacturing

Circuit breakers are critical elements in electrical systems, safeguarding equipment, preventing electrical fires, and enhancing safety and reliability. They function by automatically disconnecting the electric supply during an overload or fault, thus protecting equipment from damage. Circuit breakers also shield individuals from electrocution, lessen downtime due to electrical faults, and ensure compliance with standards and regulations. Industry requirements mandate that manufacturers test all circuit breakers to confirm they meet quality standards and perform as designed. This testing process helps identify and address any potential issues with the breaker mechanism, contact quality, or overall reliability. In addition, manufacturers can verify the efficacy of their design and production processes through testing, ensuring the circuit breakers meet the intended design specifications.

Railways & Metros

Traction motors, typically utilised in electric or diesel-electric locomotives and electric multiple units (EMUs) found in metro systems, supply the power needed to propel the train by driving the wheels. In addition, they deliver high torque at low speeds, essential for initiating and accelerating the train's movement.

To safeguard and interrupt short circuits in the overhead catenary system, electric locomotives and EMUs employ Vacuum Circuit Breakers (VCBs). These VCBs halt the electricity flow in case of a fault or overload, protecting the electrical system and the locomotive from potential damage.

Regular testing and maintenance of circuit breakers and motors are crucial to ensure safe and reliable operation. For circuit breakers, this testing involves verifying the trip mechanism's proper functioning and checking the condition of the electrical contacts. Motor testing includes assessing the insulation resistance, conducting vibration analysis, and examining bearing wear. Adhering to these testing and maintenance protocols can effectively minimise the risk of equipment failure, operational downtime, and safety incidents.

Power Transmission & Distribution LEARN MORE
Power Transmission & Distribution

Power transmission and distribution networks rely on circuit breakers and switchgear to guard against overloads and short circuits. These devices, engineered for swift and reliable operation, minimise damage and secure the network. Circuit breakers are strategically placed at vital locations within the power network, such as substations and switchyards, enabling the isolation of a faulty section without triggering a full-scale outage.

In the event of an overload or short circuit, the circuit breaker disrupts the electrical flow through the affected part of the network, thereby shielding the network from harm and averting potential fires. In addition, for maintenance staff, circuit breakers offer a means to safely isolate system faults and repair any damaged equipment or lines.

Regular testing and maintenance of circuit breakers are essential for safety and reliable operation. This involves verifying the correct operation of the trip mechanism and inspecting the condition of the electrical contacts. By adhering to proper testing and maintenance routines, equipment failure, operational downtime, and safety hazards can be effectively prevented.

Power Generation LEARN MORE
Power Generation

Motors and circuit breakers serve crucial functions within power generation systems. For example, in the context of hydroelectric power plants, turbines transform the kinetic energy of falling water into rotational motion. This motion, maintained at a consistent speed by a motor, drives a generator that produces electrical energy, ensuring efficient energy conversion.

Conversely, circuit breakers act as safeguards for power generation systems, protecting them from overloads or short circuits. When the electrical current surpasses a specific threshold, circuit breakers automatically trip, opening the circuit. This action prevents damage to the generator and other equipment and safeguards the personnel working on the system.

For the safe and reliable functioning of both circuit breakers and motors, routine testing and maintenance are essential. The testing process for circuit breakers involves confirming that the trip mechanism is working correctly and examining the condition of the electrical contacts. Motor testing, on the other hand, includes verifying insulation resistance, performing vibration analysis, and checking for any bearing wear. By diligently following these testing and maintenance procedures, we can effectively avoid potential issues such as equipment failure, interruptions in operation, and safety risks.

Oil & Gas LEARN MORE
Oil & Gas

The oil and gas industry, encompassing both onshore and offshore drilling operations, relies heavily on drilling rig equipment to extract resources from reservoirs. Key components of this equipment are circuit breakers and motors. Circuit breakers safeguard crucial electrical systems and devices, such as pumps, motors, compressors, and heaters, from electrical overloads and short circuits. Meanwhile, electric motors supply steady and reliable power to drilling rig systems and equipment, facilitating the extraction, processing, storage, and transportation of products like crude oil, petroleum, and natural gas.

Circuit breakers and motors are regularly tested and maintained to ensure safety and dependability. For circuit breakers, this involves verifying the proper functioning of the trip mechanism and ensuring the electrical contacts are in sound condition. Motor testing includes inspecting the insulation resistance, performing vibration analysis, and looking for bearing wear. Proper testing and maintenance of these components help avert equipment failure, operational downtime, and safety risks.

Shipyards LEARN MORE
Shipyards

Motors play a vital role in ship navigation and operation, powering propellers, driving generators for electrical systems, manoeuvring during docking and undocking, and operating cranes and winches for cargo handling. Ensuring the efficient and reliable functioning of ship motors necessitates proper maintenance. Dry docking at a shipyard allows a vessel to be removed from the water and positioned in a specialised dry dock for overhauling various systems, including the electrical systems that encompass the motors. Motor testing includes assessing insulation resistance, conducting vibration analysis, and examining bearing wear. Shipyards typically feature their substations with multiple incoming power lines linked to a distinct generator or power source. The substation also contains transformers that reduce high-voltage power to lower voltages suitable for the shipyard's facilities and equipment. Circuit breakers are crucial in substations, as they protect the electrical grid and equipment from damage from overloads, short circuits, and other faults. However, regular testing and maintenance are required to ensure circuit breakers' safe and reliable operation. This testing process involves verifying the correct function of the trip mechanism and inspecting the condition of the electrical contacts. Adhering to proper testing and maintenance procedures for these components helps prevent equipment failure, operational downtime, and safety incidents.
