  • Gas density monitor - GDM-100-CV - WIKA

    The gas density, for high-voltage switchgear, is a critical operating parameter. If the requiredgas density is not present, safe operation of the switchgear cannot be guaranteed. The gas density measuring instruments from WIKA warn reliably against dangerously low gas quantities, even under extreme environmental conditions.

  • Detection instruments - Product overview - WIKA USA

    Leakage in switchgear can cause high maintenance costs and, depending on the size, can quickly become a safety risk. Thus, gas leaks must be pinpointed promptly and reliably and then eliminated. Our detection instruments are used for monitoring the air in enclosed rooms, locating leakage points and for integral leak testing.

  • Leak testing note #01-01 High Voltage switchgear

    Several tracer gas leak test methods, at both the subassembly and final assembly level, can be employed for leak testing of high voltage switchgear. Consideration should be given to the methods’ ability to both locate the leak and certify the global leak tightness of the system. Both SF6 and helium can be considered for tracer gas.

  • Leak detection - Wikipedia

    Pipeline leak detection is used to determine if and in some cases where a leak has occurred in systems which contain liquids and gases. Methods of detection include hydrostatic testing, infrared, and laser technology after pipeline erection and leak detection during service.. Pipeline networks are the most economic and safest mode of transportation for oil, gases and other fluid products.
