PT Jalamas Berkatama has been providing Corona inspection services since 2002.
Using solar blind filter UV from Ofil Camera make us possible to inspect the corona at full sunlight.
Corona is a concern because it causes:
• Degradation of polymer insulators   • Crack the cement of pins and metal caps of porcelain insulators  • Wooden pole fire   • Physical damage to component   • Audio noise • Radio and TV interference ( RI ) |
Thermographic system is commonly used for electrical inspections. As electrical connections become loose, there is a resistance to current that can cause an increase in temperature. This temperature increase can then cause component to fail, potentially resulting in unplanned shutdown and injuries. In addition, the efficiency of an electrical grid becomes low prior to failure, thus energy is spent generating heat, causing unnecessary losses. If left unchecked,heat can rise to the point that can melt connection and break the circuit; as a result, fire may occur. Beside loose connections, electrical system suffers from load imbalance, corrosion, and increase in impedance to current. Thermography can quickly locates hot spots, determines the severity of the problem, and helps establish the time frame in which the equipment should be repaired. INFRARED FOR ELECTRICAL INSPECTIONS THERMOGRAPHY Inspections Thermography Locate Hot spot at phase T; Temperature °150.7 C TRANSFORMER BUSHING CONNECTIONS Hot spot at phase T because contact resistance too high (Need Retightened) After Being Retightened. All three phase connection almost have the same temperature INFRARED THERMOGRAPHY FOR MECHANICAL INSPECTIONS   A big temperature difference of identical motor under identical load ( PROBLEM) PT Jalamas Berkatama uses High resolution FLIR infrared cameras utilizing the ThermaCAM Professional reporter software to efficiently produce a high quality report detailing all problem found, and can determine the level of severity and recommended repairs.
By using a ITC level I and II thermographer you can be assured that the infrared inspection is performed in a safe manner by a qualified thermographer who has the experience and training to identify the problem and in some cases solves the problem before leaving the job site.
Infrared thermography can be applied in any situation where a problem or condition can reveal itself by means of a thermal difference. When inspecting the condition of electrical distribution equipment thermographer can “see” heat with an infrared camera. For example, sliding and bolted connections can become resistive through loosening, corrosion, etc.
Infrared thermography scanning can:
• Significantly reduce unscheduled power outages
• Detect problem quickly without interrupting service
• Asses priorities for corrective action
• Comply with insurance company requirement
WE PROVIDE THERMOGRAPHY INSPECTION FOR:
• Building electrical and installation.
• Electrical and Mechanical in Oil and Gas Industry.
• Industrial and factory facility.
• Gas leaks detection for Petrochem company and refineries industry.

PT Jalamas Berkatama offers gas leak detection services in your facilities. Using FLIR ThermaCAM GasFindIR can quickly, accurately, & affordably identifies leaking valves, flanges, pump seals, and compressors seals. The camera can visualize gas leaks in real time.
The use of infrared camera has already become a standard practice in refineries and many oil and gas companies. It’s a proactive way to identify source of volatile organic compound emissions (VOC) and repair leaking components before it’s too late. By using this service, you will improve safety and productivity and minimize emissions.  
ThermaCAM GasFindIR is laboratory tested to detect:
• METHANE  
• PROPANE
• ETHYLENE
• OCTANE
• PROPYLENE
• METHANOL
• M.E.K
• PENTANE
• TOLUENE
• BUTANE
• HEPTANE
• HEXANE
• ISOPRENE
• ETHANOL
• BENZENE
• ETHYLBENZENE
• M.I.B.K
• 1-PENTANE
• XYLENE
• ETHANE Notes:
You can download the samples video of gas leaks from www.jalamas.com/data/movie/gasfindir |
This could be happened to your apparatus:    Insulation Breakdown The HV apparatus failure can be minimized by performing the periodic testing to your High Voltage apparatus. PT Jalamas Berkatama offers services for your electrical high voltage apparatus. |
  PT Jalamas Berkatama has experience and capabilities to perform tangen delta testing on transformer , Bushing transformer, Current transformer, Voltage transformer, CVT, Lighting arrester, circuit breaker, AC motor and many other types of electrical equipment.
Using the Doble M4000 with the DTA database we are able to give immediate analysis of the device under test as compared with other similar devices and to itself if it had already been tested.
The advantages of power factor testing are it is very repetitive and it can break down a piece of equipment into sections to determine the exact location of electrical breakdown.

 Sweep Frequency Response Analysis is a tool for detecting mechanical failure or movement of windings due to short circuits, mechanical stresses or transportation. Use it to ensure transformer performance, reduce maintenance cost, and increase the service life of transformer.
PT Jalamas Berkatama has a field experience engineer and a modern tool (Doble M5300) for SFRA measurement.
|
Circuit breaker testing is conducted in order to:
• Measure the time of Open / Close of circuit breaker
• Measure the dynamic and static contact resistance of circuit breaker
• Measure First Trip current of circuit breaker
• Measure the Trip or Close coil current of Circuit breaker
• Measure the travel time or motion of mechanical part of the circuit breaker
Whether it is low voltage insulated case circuit breaker or a live tank 500 kV SF6 circuit breaker, PT Jalamas Berkatama has the specialize equipment ( Doble TDR900 ) and trained personnel to perform the testing for you. |
 PT Jalamas Berkatama has experienced field engineers and state of the art equipment to set/program ( Doble F6150 Power System Simulator), test and calibrate all made and styles of protective relays.
 PT Jalamas Berkatama tests most types of 3-Phase generation, line distance, differential and power relays from major manufacturers including:
GE, SEL, ABB, Schneider Electric, Siemens, Toshiba, Basler, etc |
 PT Jalamas Berkatama has the qualify engineer and tools for testing Current transformer and Voltage transformer.
We can perform several test for CT and VT test as below :
