Routine Tests. In accordance with the requirements of IEC 60233.
Routine Tests. All other motors shall be submitted to test (a), (b), (c), (d) and (k) of the above.
Routine Tests. All handling devices and lifting tackle supplied for maintenance purposes under this contract shall unless they are built into and form part of the equipment, be tested, marked and certificates of test provided. Lifting tackle built into and forming part of the equipment shall be operated with the maximum working load to the satisfaction of the Engineer.
Routine Tests. The following tests shall be conducted on each unit by the bidder at his works as per relevant standard - IS:2486 (Part-1)/1993 (latest amended) :
a) Visual Examination ( Clause-8 )
Routine Tests. In accordance with the requirements of IEC60137. The power frequency withstand test shall be at least 10 per cent higher than that applied to the transformer winding to which it is connected. Note: This requirement is met by using bushings rated one step higher in insulation class than that of the transformer winding, the former tested to their standard power frequency test voltage.
Routine Tests. 1.28.1 All routine tests shall be carried out on all equipment as per latest SANS and IEC standards in the presence of The Employer's representative.
1.28.2 The routine tests to be carried out by The Contractor shall include but not be limited to the following: • Measurement of winding resistance for all windings at all taps, corrected to 120°C. • Measurement of voltage ratio at all taps. • Check the voltage vector relationship. • Measurement of impedance voltage at all taps. This test shall be carried out on all taps before and after the impulse test on principal tap on the transformer which is subjected to impulse test. • Short circuit impedance and load loss at all taps. • Measurement of no-load loss and current at 90% 100% and 110% rated voltage and at rated frequency. • Dielectric tests shall be done with enclosure (Separate source voltage withstand test (High Voltage test) and Induced overvoltage withstand test. • Measurement of insulation resistance and polarization index. • 2 kV power frequency withstand test (for one minute) on control wiring. • Insulation power loss factor and capacitance for each winding and between windings.
Routine Tests. Routine tests shall be carried out on each insulator & to check requirements which are likely to vary during production as per relevant IS:731/1971 (with latest amendments).
Routine Tests. (a) Duty Cycle - All switching apparatus, when completely assembled, shall be operated ten times in the normal manner through the complete cycle with the transformer un-excited. This shall be followed by one operation in the normal manner through the complete when the transformer is energized at normal volts on open circuit.
(b) Dielectric Tests - Auxiliary circuits shall withstand the dielectric tests specified in IEC 60214.
(c) Operational Tests - The correct functioning of all control devices including limit switches and mechanical and stops shall be demonstrated. Tests shall also be made to demonstrate all aspects of the tap changer parallel control system and also compliance with the requirements for remote control of the voltage reduction facility.
Routine Tests. The routine tests shall be made on each complete prefabricated substation.
a) Voltage tests on auxiliary circuit.
b) Functional test.
c) Verification of complete wiring.
Routine Tests. Each fused isolator shall be subject to routine tests to prove compliance with IEC 62271-102 ; these must include the following:- Power frequency voltage Measurements of resistance Mechanical operation
