Following are the procedure for thermography testing of electrical panels.
Electrical panel board testing procedure.
Subject panel shall be externally examined before opening or removing any protective covers to determine the possible presence of unsafe conditions.
Ideally this is normal operating load.
Panel to be tested shall be energized and under adequate load.
Between transformers and mdb s.
The procedure for the inspection testing of circuit breakers and switches is beyond the scope of this guide as each type and voltage class has its own procedure.
Refer appendix a form 06.
Refer appendix b test circuit of insulation test.
Testing procedure of db s cu s.
Check the electrical operation of the switchgear using the schemes.
Inspection test and measurement procedures for lv and mv up to 36kv switchgears on photo eaton cutler hammer magnum ds switchgear inspection and transformer testing for mv switchgear similar considerations apply although more extensive checks on protective devices circuit breaker oil vacuum bottle contact distances are required as.
Where applicable testing of circuit breakers generally include.
As a main protection element the testing of the relay performance and settings is always included in any panel test.
Earth fault loop impedance test earth leakage test for lv distribution board shall be done recorded in prescribed format.
The different relay types relay generation and specific.
Carry out 500v megger test for phase to earth neutral to earth phase to neutral and phase to phase to measure the insulation resistance with all breakers in on positions.
Mounted in the panel using the scheme.
The following tests are to carried out in a distribution board.
Check the operation of the indicating devices voltmeters protective devices etc.
There are 3 cases to be considered.
All reading will be recorded in qc 06 quality assurance test report megger.
The purpose of this procedure is to define the step by step method to implement the correct practices for the precommissioning commissioning of submain distribution boards smdb s through the guidelines contained herein so as to ensure that the job execution complies with the project requirements and serves the intended function to satisfactory level.
Some electrical panel test procedures for ensuring the effectiveness of the different elements in the panel and their joint operation are the following.
