Embodiment Construction

[0046] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below to explain the present disclosure by referring to the figures.

[0047] refer to Figure 1a , which shows series arcing 106 in circuit 10a according to the background art. exist Figure 1a 1, a direct current (DC) power source 102 provides power between power lines 104a and 104b. Power line 104b is shown at ground potential. The load 100 connects the power line 104b to the power line 104a. Series arcing may occur in any part of the circuit 10a, such as in the power lines 104a, 104b or inside the load 100 or power source 102. Shown is an instance 106 of a disconnection or poor connection between points C and A in power line 104a, which results in series arcing. Typically, if a series arc 106 can be detected, a circuit breaker (not shown) at the ...

Abstract

The invention provides methods for arc detection in a system including one or more photovoltaic generators, one or more photovoltaic power devices and a system power device and / or a load connectible to the photovoltaic generators and / or the photovoltaic power devices. The methods may measure voltage, current, and / or power delivered to the load or system power device, and the methods may measure voltage noise or current noise within the photovoltaic system. The methods may periodically, and / or in response to detecting noise, reduce an electrical parameter such as current or voltage in order toextinguish an arc. The methods may compare one or more measurements to one or more thresholds to detect arcing, and upon a comparison indicating that arcing is or was present, an alarm condition may be set.
