Migraine or insulation tester It is a device used to measure the amount of insulation resistance of cable, dielectric or..
This device is usually used to measure very large resistances. For this reason, to measure such large resistances requires very high injection voltage, which in some cases to 10 to 12 kV is required.
In samples with a voltage of 12 kV and above, it is abbreviated as hypat.
The operating voltage of this Is between 125 volts and 12 kV. The Migraine Insulator tester has a voltage source of 12 volts, which is converted to 220 volts by an inverter inside the device, and then converted to higher voltages by means of internal transformers, and again by a rectifier. Are converted to DC voltage to be used.
Important point in using Migraine or insulation tester It is very important that the power supply is cut off before connecting the device to the circuit so that no damage is done to the circuit, and also the values shown in the Migraine Insulator tester are correct.
Before using the device Migraine (insulation tester) It is better to test the correctness of the device by turning on the device, connecting the probes of the device, separating the probes of the device, and setting the voltage selection key to the minimum voltage mode, and setting the voltage excitation chassis for Hold for 10 seconds. In this case, the device must show infinite resistance, then set the voltage to the maximum value and connect the device probes and hold the voltage excitation chassis for 10 seconds, and in this case the device resistance must be on The number should be zero. If these values are displayed in the migraine (insulation tester), the device is safe.
To test the cable, first clean and dry the cable and select the appropriate voltage for the cable or dielectric according to the standard. Connect the Migr tester to the dielectric and press the voltage injection chassis. The result obtained in operation Compare the test on the display with the table, if it is in accordance with the acceptable circuit in the table, the electrical resistance of the cable or dielectric is approved.
Including applications Migraine (insulation tester) It can be used in the manufacture of various industrial parts, inverters, input-output chokes, filters, capacitors, electric motors, bodies, wire and cable factories, power distribution networks, component factories, etc.Cianco Technical and Engineering Company By presenting a complete list of types of insulation testers or MiGs, it has been able to play a major role in the development and progress of the country’s industry and cause the increasing growth of industries.
