Breaker Insulation Resistance Test Techniques by AET

Circuit breakers are essential parts of power systems because they guard against short circuits and overcurrents. Breaker Insulation Resistance Testing is necessary to ensure their dependability. In this crucial testing procedure, Advance Engineering and Testing (AET) uses cutting-edge methods, highlighting how important it is to preserve insulation integrity.

1. Synopsis of Insulation Resistance Testing for Breakers:
Testing the resistance of the insulation materials inside the breaker to ascertain how well they stop current leakage is known as "breaker insulation resistance testing." This test is essential for locating any possible insulation flaws that can impair the functionality of the breaker.

2. Megohmmeter at High Voltage:
When testing the insulation resistance of breakers, AET uses high-voltage megohmmeters. With the use of this cutting-edge apparatus, resistance may be measured by applying a high voltage to the insulation of the breaker. This method yields accurate findings and guarantees a comprehensive assessment of insulation quality.

3. Testing for Polarisation Index (PI):
Polarisation Index Testing is an additional method that AET uses. This is measuring the resistance of the insulation over time to see how well it recovers after high voltage exposure. A high PI denotes sound insulation, whereas a low PI might point to possible problems.

4. Adjusting for Temperature:
Temperature correction is a component of AET testing methods. Because insulation resistance is temperature-sensitive, AET makes sure that measurements are corrected to take temperature fluctuations into account, resulting in findings that are precise and trustworthy.
 
5. Examination of Trends:
 
As part of their Breaker Insulation Resistance Testing, AET analyses trends. AET can detect patterns or discrepancies in the test findings by comparing them with previous data. This enables preventive maintenance and addresses possible insulation issues before they become more serious.

 
6. Extensive Recordkeeping:
 
AET places a strong emphasis on thoroughly recording the outcomes of Breaker Insulation Resistance Tests. Details on the equipment utilised, test settings, and trends identified are all included in this datasheet. With the use of this data, a thorough maintenance and testing history for the breaker may be created.
 
In conclusion, to guarantee the dependability of circuit breakers, AET's Breaker Insulation Resistance Test Techniques incorporate cutting-edge machinery, temperature correction, polarisation index testing, and trend analysis. Through early identification of insulation problems and good record-keeping, AET enhances power systems' resilience and efficiency. To know more, please visit https://aetsg.com.sg/.
