FAQ

 

1. What is an emergency generator?

   An emergency generator, also known as a backup generator, is a device that provides electrical power during a grid outage or power failure. It ensures continuous electricity supply to critical systems and appliances, keeping operations running smoothly during emergencies.

 

2. How does an emergency generator work?

   Emergency generators operate using an internal combustion engine that generates electricity. When the primary power source fails, the generator automatically starts and transfers power to the connected circuits, providing electricity until the primary power is restored.

 

3. What types of fuel do emergency generators use?

   Emergency generators typically run on various fuels such as diesel, natural gas, propane, or gasoline. The choice of fuel depends on factors like availability, cost, and the generator's intended use.

 

4. What are the key applications of emergency generators?

   Emergency generators are crucial for various applications, including hospitals, data centers, commercial buildings, manufacturing facilities, residential complexes, and critical infrastructure, ensuring uninterrupted power supply during blackouts.

 

5. How are emergency generators sized?

   Generator sizing depends on the total electrical load it needs to support during an outage. A professional assessment of power requirements helps determine the generator's capacity needed to sustain critical systems and appliances.

 

6. Why is regular maintenance important for emergency generators?

   Regular maintenance ensures the reliable performance of emergency generators. It includes periodic checks, servicing, and testing to identify and address any potential issues before an emergency occurs.

 

7. What safety precautions should be taken while using an emergency generator?

   Proper installation, ventilation, and compliance with safety codes are crucial. Generators must be placed in well-ventilated areas to prevent carbon monoxide buildup. Additionally, they should be operated and maintained according to manufacturer guidelines.

 

8. Can an emergency generator be used as the primary power source?

   Emergency generators are specifically designed for backup power and aren't intended for continuous, primary power supply. Using them as a primary power source can lead to premature wear and may not meet long-term energy needs.

 

9. How long can an emergency generator run continuously?

   The runtime of a generator depends on factors such as fuel capacity, load demand, and maintenance. Most generators can run continuously for hours to days if adequately fueled and maintained.

 

10. Do emergency generators require professional installation?

    Yes, professional installation by qualified technicians is recommended to ensure proper setup, compliance with local regulations, and safe operation of emergency generators.

ATS

 

ATS cabinet is mainly applied to the automatic switch between prime and emergency power, composing an automatic emergency power supply system together with diesel generating sets. It will monitor prime power, When it is cut off, it can automatically switch loads such as emergency illumination, security power and fire fighting equipment to generating sets. Auto start, auto transfer, auto protection, auto power supply

 

Standard configuration:

  • Control option switch, transfer option switch, emergency stop, buzzer, voltmeter, ammeter, meter, controller, ATS Switch, breaker.
  • Multiple input/output functions can be customized.
  • Standard Capacity: From 20A-3200A

 

Brand: ABB, Schneider, Socome, Suyang, AISIKAI

 


 

PARALLEL DISTRIBUTION CABINET

 

Parallel distribution cabinet is designed for the parallel running of main power diesel generator sets. The system can operate automatically or be controlled manually.

The system has the functions of automatic frequency detection, synchronizing detection and switch-on.

It is convenient to expand the capacity to satisfy the need of increasing load.

It can be used together with multiple generating sets (32 parallel generating sets max.) to control multiple diesel generating sets for automatic synchronization.

 

It offers stable frequency and voltage and can bear large-capacity load impact, achieving reliable supply, centralized management and more flexible power allocation.

 

 


 

Load Bank

 

The purpose of most land banks is used to test of the emergency generator sets, verifying all genset components are in optimal working condition under different loads. Another purpose is working combined with the generator set, to take the load of the generator set is always above 30%

 

 Advantages of Load Bank

  • Confirming the gensets output capabilities as opposed to just starting it up on occasion.
  • Finding problems, instead of when an emergency arises, savings costs and prevents future breakdowns.
  • Helps to avoid wet-stacking and cleans out any carbon deposits.
  • Confirms that the engine cooling system will work efficiently under load.
  • Makes sure that the Genset will work properly when needed.
