How to Troubleshoot HVAC Faulty Refrigeration Circuit

Smart troubleshooting of HVAC problems and malfunctions is a technique where an HVAC technician thinks very sharply and shoots skilled way. Quick troubleshooting depends on fault-finding techniques rather than the difficulty of the fault. Sometimes very simple problem kills a long span of technician time, reversely tactful technician solves the critical malfunction very quickly. 

Why Need Power Cable Test After Installation

Power Cable Test After Installation

HV/EHV power cable testing in the field after installation is a common requirement for cable users. Meanwhile, MV-normal voltage, HV-high voltage, and EHV-extra high voltage power cables are carefully tested by the manufacturer before consignment with AC-alternating or DC-direct voltage.

Transformer Winding Resistance Test by DC Current

How Do You Do Transformer Winding Resistance Test by DC Current?

Considering the basic principle of operation is to inject a DC current through the transformer winding to be measured, and then read the voltage drop across that winding. 

We may refer to the formula for DC voltage across the transformer as, V = I * R  

where, 

V= DC voltage across transformer winding;

I = DC current through transformer winding; &

R = desired calculated resistance of the transformer winding.

Magnetic Leakage of a Transformer Breaks Ideal Characteristic

How does magnetic flux determine the ideal transformer is not possible in practice?

Generally, it is assumed as our elementary knowledge about the transformer theory that the flux linked with the primary winding is also linked to the secondary winding.

You can also combine series and parallel wiring to achieve the desired impedance, which will be explained further below.

impedance refers to the load a speaker places on the amplifier.
