Introduction: Measuring the line loop contact resistance by bridges is not the ideal method as the test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model HL- 100 is a direct reading tester, and uses a test current of 100A DC, resulting in true v alue and accur ate measurements. Model HL- 100 adopts digital circuit technique and is used for measuring contact resistance of switch control equipments at test current of 100A DC. The measurements are accurate as the test is highly stable.HL- 100 is a new, fully automatic micro controlled tester that measures contact resistance at 100A DC with built in printer. The advantages of HL-100

The lightning wave impulse current generator is an impulse current generator that generates a simulated lightning current waveform . Its working process is as follows: first, the transformer charges the capacitor bank through the silicon pile, when the charging voltage reaches a predetermined value, the spark gap is triggered, and the capacitor is discharged through the total inductance and total resistance of the circuit. When the resistance is greater than or equal to the critical damping value, a unidirectional impulse current wave is generated in the circuit. When the resistance is less than the critical damping value, an oscillating impulse current wave is generated. The magnitude of the impact current amplitude is related to the circuit parameters. When the capacitance value and charging voltage are the same, the smaller the inductance value, the greater the current amplitude. In order to obtain as much current as possible, a pulse capacitor with a small inductance value is usually selected, and the total length of the connecting line should be as short as possible when arranging the main capacitor, so that the total loop inductance value can be reduced as much as possible.
