Automatic Transfer Switches are an integral part of the power generation process, allowing smooth and immediate transfer of electrical current between multiple sources and the load. When the generator is operating, the transfer switch prevents dangerous feedback of current to the utility’s system. It also ensures that different power sources are fully synchronized before their power is combined or loads are transferred, which is imperative for safe operation.

By combining ATS with our own generators, we are able to offer a complete power generation package that we support and warrant.

ATS Function & Specs

1-       ATS will control the start of generator as soon as the public Mains supply is not available.

2-      Three types of ATS is proposed and quoted:
•    ATS system in case of Mains – Generator1. – Type I (G/M)
•    ATS system in case of Generator 1 – Generator 2. – Type II (G/G)
•    ATS system in case of Mains – Generator 1 – Generator 2. – Type III (G/G/M)

3-      The ATS is 4 poles and includes bypass switch to facilitate maintenance. The panel is an outdoor type.

4-      As soon as the Mains power is available, the ATS will control the transfer of electric load from the generator installation to mains power supply. The ATS stops the duty of the generator after a certain cooling time without being in load.

5-       The operation of the generators (in case of using 2 generators) will be in 8 hours cycle as follows:
•    One on delay timer for main power
•    One for each generator taken as timed 220V AC signal from the output of its corresponding controller.

6-      In case of generator failure the second generator will start immediately.

7-       The main power is controlled by a Voltage relay (under & over voltage, phase failure).

8-      Timers installed will be:
•    One on delay timer for Main power
•    One for each generator taken as timed 220 V AC signal from the output of its corresponding controller.

9-      Timers installed will be:
•    One on delay timer for Main power
•    One for each generator taken as timed 220 V AC signal from the output of its corresponding   controller.

10-    All contactors installed with mechanical and electrical inter lock.

11-     Circuit breaker & Contactors brands used will ABB, TERASAKI, MITSUBISHI or LG (Subject to availability at time of production and customer demand).
