Week 3, 23rd April

Today, i have also been exposed to a new task, which is unloading. Unloading in power plant means to fill up the distillate that have been used for power generation purpose and the minimum level of the distillate storage in the tank must be 70 % from the maximum. The tanker will come to the power station and the distillate will have to be checked before it's being filled.

For my first time, i have the chance to have a close look about the tanker and finally i know the tanker is not what i think all the time. The big tank is actually divide it into a few compartment and then i climb up top to take a look for every compartment. The sample of every compartment will be taken in which will used to determine the purity and density of it.

As the unloading process was going, i was being explained by the person in charge to know further about the machine that we will use for the whole process.

Week 3, 22nd April

The whole day spent on connecting the ventilation fan motor for gas turbine hall. It was a suffering work as u need to do it under the hot sun as it is at the roof and the heat that come from the gas turbine. We able to finish connect 4 out of 5 of the motors as the heat that generate from gas turbine make us feel uncomfortable and slow down the process.

Week 3, 21st April

The 2 CMs (corrective maintenance) that do today is drum screen wash pump motor and lighting system in gas turbine. For drum screen wash pump motor, it is stated that current is hunting, means unstable. A free run test is done and the motor is functioned. Hence, further checking is required. For lighting system, we were required to do the functionality test or troubleshoot to check what is defect.

In the evening, we had done the BOP (balance of plant) motors PM inspection. We were required to take the reading of the motor’s temperature and bearing vibration. The motors that we inspect are service water make up pump motor, demineralized water transfer pump and sea water booster pump.

Week 3, 20th April

Due to the request from the admin staff, we were required to install a new fax cable line at the admin office. The wire goes through from the ceiling of the admin office and reaches the connection point. The connection of the wire must do carefully as the wire is life.

In the evening, I and abang Fadzli checked the transducer in the power transformer as the reading of the measurement is out of range. After a round of checking, we found out that the problem is the transducer problem. A new transducer will be replaced when the ordered transducer reached. Other that involve is Mr. Tai, control and instrumental technician.

Week 3, 19th April

In the morning, we had been instructed by En. Sharif to install a new streetlight near the guard house as the old light had defect. A skylift track is used to bring us up. The process of installing did not go as smoothly as expected. After taking out the old light, the wires that connect the circuits went into the hole of the post. We need to use a long wire to pull it out and it wasted a lot of time. After the wire successfully taken out, the installation process went smoothly and testing is done. The light is function and job done.

In the afternoon, I and abang Razak were required to do the cathodic protection system preventative maintenance. We need to take the reading of control reference setting which is 1 connect resistance side and 1 at ground side and measure the voltage. For anode performance, it also requires to take the voltage reading which can directly take from the screen.

During the free time, I also taken the opportunity to check the steam turbine generator transformer protection relays at steam turbine generator control panel. This is the assignment given by Sri Daran. I had been ordered to check the relay whether it is in the list and at the side and the quantity must be correct too. Besides that, I also able to check the 6.6kV/415kV switchgear panels at switchgear room for steam turbine. Same process for gas turbine protection relays.

Week 2, 15th April

Holiday for Malacca state...wakaka

Week2, 14th April

En. Sharif explained to me how the power plant is operated and the function of a tap changer in the transformer. it is a good additional knowledge to me.

The PM that needs to do today will be carbon brush PM inspection. The instruction is check carbon brush and air filters. The carbon brush needs to be replaced when the measurement is less than 60mm. A normal carbon brush is 100mm long.

Due to the installation of ventilation fan yesterday, the PM for water treatment plant motor PM is done today. It is required to check the on load current, insulation resistance, bearing vibration and body temperature.

Besides the PMs, the condenser fan motor for air condition 1B at center control room also not function. Hence, we need to go to do the checking. Further checking had been done and found out that the condenser 1 motor winding is short circuit and wire for condenser 2 that connect to neutral is disconnected. After the adjustment and install the new motor, both the condenser is functioning.

Week2, 13th April

I have been involved in installing the ventilation motor for the gas turbine hall. It is required to climb up the roof and hence, it was a little bit scary. After take time to settle, I am fine with the condition. The motor is taken up by the crane that rent by the plant. It is required to install 6 ventilation units, but due to the size of the crane that can’t reach the part of the hole, we have just finished installed 3 units. The other technicians that involved is abang razak, abang Fadzli, Mr. Tan and abang Adib.

Week2, 12th April

Today the job will be dealing with one checking and preventative maintenance. It is reported that the center control room air condition 1B tripped off after started and hence we need to check the control circuit and compress motor. I followed abang Razak to do the checking and the motor is in good condition.

Next is the steam turbine motors PM inspection. There are 2 inspections, general electrical and general physical inspection. For the electrical inspection, we checked for the on load current while for the physical inspection, we checked the bearing vibration and body temperature for the motor. There are 4 types of vibration need to be checked, that are non-driving end (NDE) X and Y axis and driving end (DE) X and Y axis. Each of them must be measured and the reading is recorded.

Week 1, 9th April

There are 2 PMs to do today, emergency diesel generator panel and fire diesel engine battery. For EDG, I and Mr. Tan do the visual inspection general cleaning and local panel battery inspection.

For diesel engine battery, we also do the same procedure. Besides that, we are required to take the reading for SG and voltage of the battery. The total voltage for a battery bank is around 24-27V.

In the evening, Mr. Sharif, supervisor of ECNI department, asked us to the control room to show how to switch on the water pump. Circuit breaker SF6 is used for 6.6kV and 415V circuit. When an accident occurred, circuit breaker is used to break the circuit.

The function of a differentiator of current is to check then three phases current is balanced or not. If it is not balance, it will sense by the current differentiator and circuit tripping will occurred.

The pump 1A is tested at the evening. Free running testing is used and after no error occurred, the connection with the shaft is connected and another testing is done. The vibration for the water pump after the repair had reduced.
