Electrical Engineering Fundamentals

Technical Knowledge

• AC vs. DC Current: AC (alternating current) reverses its direction periodically, while DC (direct current) flows in one direction. Key differences impact applications.

• Electrical Circuit Components: A circuit includes a power source, conductors (wires), components (resistors, capacitors, inductors), and a load (the device using the power).

• Transformer Working Principle: Transformers use electromagnetic induction to change voltage levels. Changing the number of turns in coils alters the voltage ratio.

• IEC 60502-1 Standard: This standard sets safety requirements for electrical cables, ensuring quality and reliability for diverse tasks.

• Power Factor: Power factor measures the ratio of real power to apparent power in an AC circuit. A high power factor is desirable because it improves equipment efficiency. Low power factor results in higher current demands.

• Electrical Conductors: Conductors facilitate current flow. Examples include copper, aluminum, and silver. Different choices depend on factors like cost, conductivity, and application needs.

Sales Knowledge

• Successful Sales Strategy: A successful sales strategy involves identifying target customers, tailoring offerings, building relationships and using effective sales techniques. Specifics depend on the products and sector.

• Handling Objections: Recognizing objections and addressing concerns directly and professionally helps gain customer trust and potentially close the sale.

• Customer Relationship Management (CRM): CRM systems help businesses manage interactions with customers, improving sales and relationship building.

• Industry Trend Awareness: Staying updated with changes in the electrical industry, through industry journals, online resources, and conferences helps cater to evolving needs.

Problem Solving

• Convincing Unsure Customer: Understanding the customer's concerns and focusing on their specific needs (e.g. cost savings, warranty) builds trust and overcomes reluctance. Demonstrating how the product solves problems can be helpful.

• Addressing Product Issues: Listening to the client, understanding the issue, and offering prompt, professional solutions, potentially involving replacement, repair and customer support are vital. Taking responsibility and delivering solutions are essential for maintaining client relationships.

Communication Skills

• Email to Potential Client: Email introductions introduce the company's capabilities and specify products or services, including contact information.

• Persuading Client to Choose Your Product: Recognize their needs and concerns. Highlight your product's unique features and advantages and differentiate it from competitors, while remaining professional. Demonstrating expertise can be beneficial.

Practical Test

• Product Demonstration: Demonstrate product features, benefits, warranty, and customer service options. Provide clear answers to potential technical questions and close efficiently.

• Technical Troubleshooting: Accurately analyze the issue and diagnose potential problems (e.g., faulty circuit, poor connections) through logical steps and tests. Clearly propose a solution with necessary steps and material.
