High voltage test laboratory

    High voltage test laboratory (electrical checking) is useful for detecting defects on low and medium voltage electrical cables, perform high voltage tests, detect insulation failure and underground electrical routing, periodically check-up of electrical protection on vessels and platform energy systems; Besides the usual checking activities there are two major issues that can be solved using electrical methods of RIG OILFIELD SERVICES LLC:
    - One big concern is represented by nonlinear loads that cause harmonics to flow in the power lines (harmonics - unwanted currents that are multiples of the fundamental line frequency). Harmonic currents can overload wiring and transformers, generating additional costs and creating heat, malfunctions and, in extreme cases, fire. So, it is important to know when and how to address this issue. Our measurements can determine the causal factors and the means to correct them, with results in reducing costs. These measurements are made with harmonics analyzer Chauvin-Arnout CA 8220;
    - Another significant problem that can be identified using our equipment is represented by neutral power factor value < 0.92 which causes increased costs invoiced by power distributors. Our measurements can determine the causal factors and the means to correct them, with results in reducing costs. These measurements are made with cos ᶲ meters.
