How to Use IR4053 Insulation Tester
This video shows the measurement flow of the PV system insulation resistance using the IR4053.
Measurement not affected by generating PV
The IR4053, which was designed for PV, can accurately measure insulation resistance without being affected by the generating PV.
Accurate and safe measurement without creating shorts
Normally, to accurately measure the insulation resistance of a generating PV, one needs to short the measured circuit. With the IR4053's PV measurement mode, short circuiting is not necessary.
Displays measurement in 4 seconds
The IR4053 displays the measured value just 4 seconds after starting measurement. After the first display, the displayed value is updated each second. Comfortably carry out swift measurements.
What are the problems with conventional insulation testers?
Problems with conventional insulation testers and the 2 measurement methods determined by recognized guidelines
Measurement that does not involve a short-circuit
This is not as dangerous, but depending on the circuit status, the measurement may be affected by the generating PV and may produce a result different from the actual insulation resistance.
Measurement that involve a short-circuit
To accurately measure a generating PV, one needs to short the measured circuit, which requires that a short-circuit switch be separately installed. Short-circuiting will also pose the danger of creating an arc. In addition, to minimize hazards, it is recommended that the testing be conducted at night.
Functions useful in the field
Comparator function/ Red light
You can compare measurements to any set values. If the result does not meet the set value, the red light will warn of nonconformance.
Test lead with remote switch
This allows you to apply output voltage with the switch in your hand, work with a light, and see the result of the comparator with an LED.
Drop proof
The sturdy design will not break even if dropped onto concrete from 1 m, so you can use it with peace of mind.
SPECIFICATIONS
Basic specifications: PVΩ measurement
Accuracy guaranteed: 1 year
