Open Circuit Fault in Central and Southern Maine

Open Circuit Fault

An open circuit fault is a break in the line, which can cause a loss of power and/or short circuit protection. It is less disruptive than a short circuit fault, but still needs to be addressed by a professional. Casco Bay Electric’s technicians have the expertise to locate these faults quickly and accurately. Our fault location services include high voltage tests, voltage drop tests, loop impedance measurements, current injection testing, cable tracing, and visual inspection.

Short Circuit Fault

There are two main types of short circuit faults: symmetrical faults and unsymmetrical faults. When a symmetrical fault occurs, three phases are short-circuited. You may hear a symmetrical fault referred to as a three-phase fault. An unsymmetrical fault occurs when the magnitude of an electrical current is not equal and is displaced by at least 120 degrees.

Causes of Cable Faults

Cable faults can have a variety of causes. However, many occur due to moisture entering the cable’s insulation. Moisture can corrode the insulation, leading to a short circuit or open circuit fault. Other potential causes of cable faults can include physical damage, aging and deterioration, improper installation, loose connections, and faulty components. Lead sheaths in older cables can also become damaged when lead crystallizes as a result of vibration.

Different Methods of Fault Location

There are two main methods of fault location: the online method and the offline method. The online method takes a sample of the current and voltages in order to identify the fault points. This method is often used with underground cables. The offline method uses a special instrument to measure the line length and resistance. This method is typically used for overhead power lines, as it does not require any current flow through the conductor.
