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, 16th April

The 3 ventilation fan motors that haven’t install is being installed today. This time a bigger size crane is rented and the job is finished by afternoon. This time, Zulklifi and Saw, both trainees also went to the roof to observe our work.

After the lunch, a knowledge sharing session is held at the training room. Mr. Yunos, control and instrumental supervisor share his knowledge about pneumatic actuator. It is a good additional knowledge to all of us.

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.
