As leaders in our home, work, and community, our job is to make more leaders.

Our job is to inspire.
Our job is to help others be their best.
Our job is to leave the world a little bit better than how we found it.
Our job is to leave a legacy of influence, even after we’ve departed.

Authentic leadership is not about you.

Leadership is about making everyone around you better and inspiring them to achieve the impossible.

The DC system in the stations is chargers + batteries.

Inside each station is a battery room conversion station, with acid battery sets (alkaline at some stations used to feed prevention and emergency services (220/110 volts) as well as communications circuits (48 volts).

Batteries are periodically tested, including measuring internal resistance, measuring column voltage and battery fluid concentration.

At some stations, all batteries are located in one room, and in some stations each battery set is located in a separate room, and a separate room is allocated for battery charger chargers, and is not placed with the battery room so as not to be affected by gases coming out of the batteries.

Many of the devices inside the stations are controllers or protective devices that operate in the continuous current and not the AC, and when isolating the station from the electrical grid the batteries are the only source of current available and therefore should take care of the maintenance of the batteries and ensure their powers.

Because of the importance of these systems, battery capacity is always taken into account to be sufficient to operate the plant for at least 8 consecutive hours.

When calculating the size of the plant's batteries before starting these calculations, you should know the types of loads that feed on batteries and the duration of each load. In general, the station has three types of loads from the battery point of view:

Connected loads such as lighting loads, communication devices and internal radios as well as Continuous charged coils, which are battery-related loads connected to the battery also connected to the charger.

Loads run intermittently non continuous loads and at unspecified times, some of which are automatically separated and some may continue after running for long periods such as ventilation loads, emergency bulbs, fire systems etc.

Loads that work lightning-fast momentary loads (briefly) but they are loads as high as the start-up car. annunciators load

Here we will present a simplified picture of battery size calculations, note that the standard specifications -1115-IEEE 2000 give a detailed method and take into account many factors such as the obsolescence of battery life, temperatures and others.

We also point out at the beginning that the battery capacity changes according to the value of the current withdrawn, the battery capacity of 100AH does not give as some imagine 20 amps for 5 hours, or 10 amps for 10 hours, this is a common mistake but the available capacity of the battery changes according to the value of the current withdrawn from it and therefore the following factors are frequently used

Capacity rating factor,Kt=(Nominal Capacity (AH))/(Performance (Amp))

We also note that the number of cells is calculated from the knowledge of the lowest effort allowed to descend to it divided by the least effort reached by the cell, for example if the nominal voltage of the station is 220 volts (DC) but allows to descend up to 198 volts, if h is the lowest effort per cell up to 1.0767, the number of cells is calculated from the following equation:
No.of cells=(min allawable system voltage)/(end cell voltage)=198/1.076=184Cell

TRANSFORMER TESTING (COMMISSIONING AND MAINTENANCE )

Electrical power transformers transforms electrical energy from one circuit to another using mutual induction between two windings. It transforms power from one circuit to another without changing its frequency. Transformers are tested to give an indication to which extent they comply with specified requirements set out by the Utility or Customer. It also determines their electrical, thermal and mechanical suitability for the system in which they will be applied. Certain tests are done at the factory (manufacturer) before the transformer is delivered to the customer and some tests are carried out at the consumer site on commissioning and periodically.

1. Ratio Test

The ratio test ensures that the transformer windings have the proper turns to produce the voltages required. The ratio is a measure of the voltage applied to the primary terminals to the voltage measured at the secondary terminals.

2. Winding Resistance Test

Measuring the resistance of the windings assures that the connections are correct and that there are no anomalies such as loose connections, high contact resistance in tap changers.

3. Short Circuit Impedance Test

This test is performed to ensure the stated nameplate impedance and the measured transformer impedance match. A high power voltage source is required to excite the HV winding of the transformer, whilst the LV is short circuited.

4. Load Tap Changer Test

The tap-changer contacts are tested for electrical continuity during tap-changing. By applying a constant current while tapping, the tester looks for open circuit transients during tap-changing. Bouncing or High Resistance Contacts cause arcing and possible tap changer or transformer failure if left undetected.

5. No Load Test

This test verifies the design and core performance by indication of the no load current drawn by the transformer. The magnetisation current is a factor of losses in the electric circuit, losses in the magnetic circuit, and losses in the dielectric circuit. A high power voltage source is required to excite the HV winding of the transformer at the impedance voltage whilst the LV is left open circuited

6. Tan Delta Test

The Tan Delta is a measure of the dielectric loss when the dielectric is subjected to an AC electric field. The AC field is a result of voltage applied between a conductor and the outer capacitive foil in the case of the bushing or C.T. and for transformers between the conductor and the tank or core or other windings. Results recorded on site should be compared to nameplate or factory recordings.

7. Sweep Frequency Response Analysis (SFRA)

SFRA tests are special tests, sometimes performed as part of the commissioning tests, during preventative maintenance and after fault trips. SFRA assesses the mechanical condition of transformers, and is one of several methods used to detect mechanical failures. The tests are to be done on the transformer prior to dispatch from the factory and similar tests done when the transformer is finally installed and commissioned on site. A comparison is then made of the reference thumb prints obtained prior to the transformer leaving the factory and the thumb print obtained during commissioning.

8. Insulation Resistance and Polarization Index Test (PI)

The purpose of this test is to check that the transformer is not put into service with compromised insulation. The insulation of a transformer can be compromised by the following causes:

- Water contaminated paper or oil.
- Heat damaged insulation due to severe overloading or a transformer fault.
-Mechanical damage due to poor transport preparation or a fault.

Most people will never understand how something so simple can mean so much to a person. To most this is a suitcase full of clothes, to me it’s a lifestyle most will never understand. This simple suitcase full of clothes means that I’m gone away from home, working trying to give myself a future and my family a better lifestyle. It’s always another hotel, another job site, and those are just a few things. It also means it’s another day away from missing everything back home whether it’s family, friends, a significant other or even all of the above. It’s long days and even longer nights, you get off work and you want to talk to everyone back home and stay in constant contact but most nights it's too late and all you can manage to do is shower, eat and passout to get ready for that early morning coming up fast, and all I hear is “must be nice”... It pays good, and you can afford nice things, but it’s all at the cost of missing everything else back home.. so before you say “must be nice” ask yourself if you can do what us hardworking men and women do, because to me it must be nice to be home with your loved ones all the time..

Cheers to all the hardworking people👍🏼🍻
