What is the testing standard of insulation resistance in electrical code,

The formula is as follows: r = u / (1000 + P / 100)
R -- insulation resistance (m Ω);
U -- rated voltage of motor (V);
P -- motor power (kw)
However, the actual work is generally carried out as follows:
1. Low voltage equipment below 380V measured by 500V megger (megger) is qualified if it is greater than 0.5 megohm
2. For equipment above 1kV, use 1kv or 2500V megger to measure the insulation resistance. For example, 6kV equipment requires 6m Ω, which is similar to that calculated by the above formula

How to fill in insulation resistance test record
It's about the distribution box. How to fill in it

There are two kinds of insulation resistance test records in common building construction
1. Insulation resistance test record of line equipment
Loop number (example m1-n1),
Specification and laying method
(example bv-4x10 + bvr-1x10 / sc32 / FC)
(example bv-2x4 + bvr-1x4 / sc25 / WC)
Resistance value: three phase five wire full fill,
The lattice corresponding to single phase filling
(for phase B, the socket circuit is filled with B-N: 30, B-PE: 31, N-PE: 31)
The values should be close to each other
2. Cable laying and insulation resistance test record
Cable number (example p2-m1),
Specification: yjv-4x25 + 1x16
Starting point: P2 box
Destination: M1 box
Laying mode: pipe laying or bridge laying
Intermediate joint: none or 0
Relative phase: 80, relative Zero: 80, relative ground: 79

Insulation resistance test record
I want to know how to fill in this form. The project has been completed, but I don't want to test it. I just want to know how to fill in the form according to the standard. I want to give some actual values, such as the name of equipment line A-B? B-C? And so on. Thank you!

I can't see the form of your form, I do quality, our quality of insulation resistance test records will generally write the following several important information: 1. Test equipment: XX model insulation resistance table 2. Test conditions: XX VDC voltage (General Factory engineering use 500VDC test) 3. Test location: write or mark your two tests

On the measurement of insulation resistance
Use a megohmmeter to measure the insulation resistance of the circuit and the motor. How many results are qualified?

It is generally believed that 2 megabytes is insulation. You can also see the insulation grade marked on the electric appliance, and then look up the table
