4) Modes of Operation: Measurement Mode and Normal Operation modes will be provided as follows.
Measurement Mode:
- In Measurement mode, for Output Voltage and Output Current terminals will be provided to measure the same by using an Oscilloscope.
- For this mode, Switch, under test will be kept in ON position.
- In this mode, Load would be Switched on at 900 ± 5 phase-angle. To achieve this necessary controls will be provided.
- Digital Oscilloscope will be provided to measure and display Ipeak
- Provisions to adjust/select suitable time.
- I2t will be calculated (by necessary means/software) and displayed.
Normal Operation Mode:
I. Measurement Terminals: For the measurement of Output Voltage and Output Current Suitable Oscilloscope terminals will be provided.
II. SBL Load Adjustments: For the adjustment of Output Current and Time to get the
desired valves of Ipeak and I2t, adjustments for R2 and C will be provided.
Consists
1. 3 Nos. of Voltmeter, Wattmeter, Current meter for 3 samples.
2. Variable transformer to adjust the voltage as desired.
3. The resistance & capacitance Bank as per the standard to test 3 samples of type each of 4 Rating.
The entire Load Bank is housed in aluminium extruded section and powder coated DA Grey colour.
The system is also built-in to ensure peak current as per table 22 column No. 1.
It can be verified on oscilloscope (Not part of Load Bank).
