Equipment Testing And Diagnostics

Avoid Unplanned Outages with Reliable Electrical Equipment

Sky Engineering has been an electric motor, transformer expert since decade. Experience, combined with high levels of engineering education, is the foundation of our industryleading electrical motor testing and analysis procedures designed to reveal even the most complex electrical equipment problems. Diagnosing the cause of the problem is at the heart of our electrical equipment testing and services. Whether testing the equipment for electrical glitches or mechanical hitches, we provide with the solution to the problem.

Comprehensive Equipment Testing

Our extensive testing includes a wide-range of diagnostic exercises for general motor, transformer, switchgear evaluation and to identify underlying issues, including:

Electrical Testing

Sky Engineering has placed a priority on investing in our test equipment technology to provide accurate data reports for quick and reliable diagnostics. Our testing is comprehensive for insulation testing, circuit analysis, thermography, winding analysis, and partial discharge testing that will reveal a real conditional assessment.

Insulation Testing

Electrical equipment insulation testing and our technicians have all the newest tools to make sure your insulation is holding up to abnormal conditions. We provide Dielectric Absorption, Power Factor, Insulation Resistance, Polarization Index, Surge, and HiPotential Testing.

Proving the winding insulation systems are within specification or best is the purpose of the extensive insulation testing processes. Dielectric absorption, power factor, polarization index (PI), surge, or high potential (hi-pot) testing eliminates guessing and proves out your motor’s insulation strength.

Circuit Analysis

A problem with an equipment will vary, but our dynamic equipment circuit analysis will diagnose performance of the equipment while in-operation with or without load. Conditional testing is an accurate dynamic test for any electrical equipment condition. Measuring electrical characteristics like impedance, inductance, and capacitance provide condition information.

Thermography

Our thermal imaging and thermal video is a fast and safe method of equipment testing to identify electrical and mechanical problems. Heat is the enemy of any electrical or mechanical system. The Infrared “IR” technology provides accurate temperature images within 1 Degree Fahrenheit difference in real-time, using infrared to detect the hot spots on your equipment. Sky Engineering has a proven track record of identifying and recalibrating your equipment to be efficient and reliable, which will extend the life of the equipment. We will pinpoint any system problem and provide service and repair options to keep the system operational.

Winding Analysis

Sky Engineering is the leader in the motor and transformer winding analysis and performs non-destructive and in-place trending of electrical machines. Our study provides necessary tests to know the equipment’s winding insulation statues and helps to reduce any future losses.

Partial Discharge Testing

Transformer and Motor partial discharge testing of insulation systems that reveal defects not visible to the naked eye. We take the time to test your electric motor, so we save you time and money

Root Cause Failure Analysis/Conditional Assessment

Root Cause Failure Analysis is the process of identifying the source causing a particular failure and using that data to create an approach for corrective/preventative action. We design a plan of action to make repairs that directly correct failures discovered in the RCA.

Vibration Analysis

Sky Engineering is well experienced to measure vibrations in rotating equipment. Our tests will find wear and tear before you experience a catastrophic failure.

Balancing & Laser Alignment

The alignment of your rotational equipment can cause high wear and tear to your motor, if it is not valid, our service centers have high-tech equipment that utilizes lasers to find perfect equilibrium, and detect out of balance defeats. Our accurate instruments and comprehensive diagnostic reports can evaluate your electrical and mechanical equipment precisely.

RELAY TESTING

Application check, installation, testing, calibration and commissioning of protective relays of make like Areva, ABB, Toshiba,Hitachi, Omron, Fuji, GE Multilin, AVK SEGC, Siemens, etc. makes are tested.

OVER CURRENT/EARTH FAULT RELAY(50/51/50N/51N/67/67N)

  1. Pickup , Drop off & Threshold Test
  2. I-t characteristics curve test
