Insulation Resistance Test

1.      OBJECTIVE

This Method of Statement is meant to describe in generality the Insulation Resistance Test process; which describes its general setup and how the test is carried out.

2.      SAFETY

All personnel should continuously and consciously observe his work area for any potentials danger and take adequate measures.

In general:

a)     All personnel should wear Personal Protective Equipments suitable for the work and work area (e.g helmet, safety boots, goggles, glove, etc)

b)       If working in live station, ensure that isolation is done and Permit To Work is issued. If possible, ensure no REMOTE operation is allowable such as put the section into LOCAL.

c)        Do not touch the injection cable when the testing in progress. If possible, make a distance around the test perimeter.

d)       Ensure fully discharge the apparatus once the test was done.

e)        Ensure that the working area is only at the permitted area

f)         Earth/ground test equipment

3.      GENERAL INSULATION RESISTANCE TEST

a.         General Setup

For this Method of Statement, we use KYORITSU High Voltage Resistance Tester as our test equipment.

Setup the equipment as shown in Figure 1 as we are going to measure the insulation resistance value of the circuit under test.

Ensure firm contact of test equipment cables and objects under test.

b.         Test Process

Having the setup prepared, the test itself is quite simply. Set the range switch to desired insulation resistance range.

1.    Phase to Ground Insulation Resistance Test.

-    Set the red lead to LINE and black lead to EARTH on the test set. Connect the LINE lead to primary terminal and EARTH lead to ground point.

-    Select range to 5kv then press the PRESS TO START button and measure for 1 minute.

-     The measurement value can be collected from the LCD monitor.

-      Record down the result.

2.         Phase to Phase Insulation Resistance Test.

-   Set the red lead to LINE and black lead to EARTH from the test set. Connect the LINE lead to primary terminal and EARTH lead to secondary point.

-      Select range to 5kv then press the PRESS TO START button and measure for 1 minute.

-      The measurement value can be collected from the LCD monitor.

-    Record down the result.

Earth / Ground Test (version 2)

1.      OBJECTIVE

This Method of Statement is meant to describe in generality the Earth Grid Test process; which describes its general setup and how the test is carried out.

2.      SAFETY

All personnel should continuously and consciously observe his work area for any potentials danger and take adequate measures.

In general:

a)      All personnel should wear Personal Protective Equipments suitable for the work and work area (e.g helmet, safety boots, goggles, glove, etc)

b)      If working in live station, ensure that isolation is done and Permit To Work is issued. If possible, ensure no REMOTE operation is allowable such as put the section into LOCAL.

c)      Ensure that the working area is only at the permitted area.

d)     Earth/ground test equipment

3.      GENERAL EARTH RESISTANCE TEST

a.         General Setup

For this Method of Statement, we use KYORITSU Digital Earth Resistance Tester as our test equipment.

Setup the equipment as shown in Figure 1;

-            Stick the auxiliary spikes P and C into the ground deeply. They should be aligned at an interval of 5-10mtr from the earthed equipment under test. Connect the green wire to the earthed equipment under test, the yellow wire to auxiliary earth spike P and the red wire to the auxiliary earth spike C from terminals E, P and C of the instrument in order.

-            Set the range switch to the EARTH VOLTAGE position in the condition of

1.    Earth voltage will be indicated on the display. Make sure that the voltage is 10V or less. When the display reads more than 10V, it may result in excessive errors in the earth resistance measurement. To avoid this, make measurement after reducing the voltage by turning of the power supply of the equipment under test etc.

b.                 Test Process

Set the range switch to 20Ω position and press the push button (PRESS TO START). LED remaining laminated during the testing. Let the device for a few second and the measured value will appear on the LCD Display.

If the auxiliary earth resistance of auxiliary earth spike C is too high to make measurement, the display reads ‘….’ Recheck the connection of the test leads and the earth resistance of auxiliary spikes.

c.                  Test Acceptance Value

-      Resistance value for earth rod - less than 10Ω

-      Resistance value for earth rod with cooper tape  - less than 1Ω

Earth / Ground Test (version 1)

Green,Yellow,and Red.The "Green" one we connected to the COPPER ROD while the red and yellow one,we struck them on ground.

STEPS.

1. Set Range x1Ohm.

2. Press Red Button "Press to Test".

3. If the needle goes to the end of the scale(green meter),mean,the copper rod should be buried deeper.

4. If the needle is below than 2Ohm,meaning,the grounding is just good enough.


Note :

1 Copper Rod is about 6 feet long.Normally,a suitable deep for grounding is about 18 feet.So,3 Copper Rod is just good enough for grounding.


Make sure supply from transformer should be OFF state.

Route To Be Professional Engineer (PEng or Ir.)

Kepada pemegang-pemegang Ijazah Sarjana Muda Kejuruteraan Elektrik (Kuasa), berikut adalah langkah-langkah ke arah menjadi seorang Jurutera Professional (PEng or Ir.) :

1. Daftar sebagai Jurutera Siswazah di Board of Engineer (BEM) secara online, pendaftaran biasanya mengambil masa 1 hingga 3 bulan, pastikan semua salinan disahkan oleh Jurutera Professional (sebaik-baiknya sama bidang dengan anda) atau disahkan oleh Pesuruhjaya Sumpah.

2. Selapas anda berjaya didaftarkan sebagai Jurutera Siswazah, hadiri 3 kursus wajib di Institute of Engineer Malaysia (IEM), iaitu kursus Code of Ethics, Engineering Management dan Safety and Health. Yuran bagi setiap kursus adalah RM350.00, jumlah semua RM1050.00.

3. Kemudian anda perlu menghadiri kursus yang berkaitan dengan Engineering Discipline anda, contohnya Electrical, perlu hadir kursus Power System Protection, Power Transformer dan lain-lain. Jumlah kursus yang perlu hadir adalah 4 kursus (6 jam setiap kursus).

4. Kemudian perlu hadir seminar,talks, meeting dan community service bagi mendapatkan 30 unit CPD.

5. Cari pengalaman 3 tahun, pengalaman untuk hadir Professional Interview di ambil kira dari tarikh graduate, manakala pengalaman untuk daftar sebagai PEng bermula dari tarikh berdaftar sebagai Graduate Engineer. Setelah cukup pengalaman 3 tahun hadir Professional Interview (PI) di IEM, kena bawa report pengalaman sekali. Jurutera Siswazah boleh diketegorikan kepada 3 jenis :

5.1 Jurutera Rekabentuk, biasanya bekerja dengan perunding M&E, buat estimate harga, design single line diagram, lukisan AutoCAD, meeting dengan client, lawat tapak dan lain-lain lagi.


5.2 Jurutera Pengajar, biasanya mengajar di Universiti, kolej dan institute, sebaik-baiknya mengajar di tahun 3 atau 4 program yang di accredited oleh Engineering Accreditation Council (EAC), tapi kalau program tidak di accredited ada option lain iaitu just ambik Master in Elec. Eng. (M.E.E) secara full time. Walau bagaimana pun Jurutera Siswazah perlu ada practical experience selama 1 tahun di Industri.


5.3 Jurutera Penyelenggaraan, yang nie paling best sebab boleh buat Competent Engineer dan Servicing Engineer kat Suruhanjaya Tenaga, tetapi kena buat log book sama macam Chargeman dan Wireman, log book perlu disahkan oleh PEng yang same branch dengan kita (contonhnya Electrical). Baca buku Akta Bekalan Elektrik 1990 serta Peraturan-Peraturan Elektrik 1994 untuk lanjutan.

6. Selepas LULUS interview, perlu menduduki peperiksaan, ada dua paper, pertama Code of Ethics, dan kedua Essei Pengalaman Lepas.

7. Itu sahaja, anda LAYAK untuk berdaftar sebagai JURUTERA PROFESSIONAL (PEng atau Ir.).
