Video on the usage of the PV insulation resistance meter IR4053-10

Introduce the PV Ω measurement function that can stably measure the insulation resistance of PV in power generation, and display a video of the specific steps for using it.

Product Introduction Video

Insulation resistance measurement unaffected by solar panels in power generation

The IR4053-10, specially designed for measuring insulation resistance of solar panels, is not affected by power generation and can accurately measure insulation resistance values.

Problems in insulation measurement of solar panels in the past

According to the two measurement methods specified in the JEM-TR228 guidelines of the Japan Electric Machinery Industry Association, as well as the issues with previous insulation resistance meters
Measurement method without short circuit
The risk is relatively low, and depending on the state of the circuit, it may be affected by PV during power generation, which may result in measurement results that are different from the actual insulation resistance state.
Measurement method for short circuit
In order to accurately measure PV in power generation, it is necessary to perform short-circuit measurements on the measurement circuit.
Additional short-circuit switches need to be installed, which may pose risks and hazards.
Moreover, to prevent potential hazards, it is generally recommended to conduct measurement work at night.

The insulation resistance meter IR4053-10 with PV Ω range can accurately and safely measure without short circuit

The measurement method without short circuit usually involves measuring the insulation resistance when it becomes unstable after insulation measurement, and then measuring it when it becomes PV Ω.
Can accurately measure without being affected by solar panels.

Quick measurement value display accelerates work progress

After the measurement starts, the measurement values will be displayed on four sides.
After the first display, update the display value every 1 second.
Quick measurement, convenient and comfortable usage.

Use the comparative judgment function to determine whether the measurement results are qualified or not

After setting the standard value, a value above the standard value is considered PASS, and a value below the standard value is considered FAIL.
When determining FAIL, a continuous beep sound and a red light on the display screen will be used to notify.
Therefore, the results of qualification are clear at a glance.

Convenient measurement switch, excellent operability

It can be operated with just the thumb.
Press the switch to measure words, and turn on the switch for continuous measurement.

Starting and stopping remote measurement using a testing line

By using a test line with a switch, measurement can be started and stopped at the test line.
There is also a small light at hand for easy operation in the dark.

Durable design for safe on-site use

The anti drop design that can withstand a drop of 1 meter from concrete is reassuring even for on-site use.
