Surge and Lightning Counters
Electrical surges are high frequency current events that present potential danger to sophisticated electronic devices. Electrical surges can occur at almost any time, and the most common causes are lightning strikes, the switching of inductive loads, power grid disturbances, general fault or arcing conditions. In the case of a direct lightning strike the damage caused by surge current is clearly felt and often visible, however many other electrical surge events can go unnoticed. The consequences of such ‘quiet’ disturbances can be just as detrimental to the operation.
Surge currents can cause loss of data transmission, switch tripping, disturbance of machine control systems and a slow degradation of circuit elements. In addition, a surge can be an indicator of a short circuit which causes currents of power to travel along unintended paths with little or no electrical impedance, for example after a blackout or wiring insulation damage.
Raycap’s ProGRID surge and lightning counter solutions have different capabilities that can sense, record and transmit the occurrence of otherwise undetectable surge currents, enabling users to take preventive measures and plan appropriate maintenance.

Surge Protection Device and PV String Monitors
ProSMS 8 ProSLS ProSCT ProALARM
Most Surge Protective Devices (SPDs) are designed to be self-sacrificial, often failing in order to protect more expensive equipment downstream. In essence, their life is based on the magnitude and frequency of surges they have diverted and absorbed. This means that at some point in time they will reach their end-of-life. This will be due to many small surges, or one large surge which exceeds the specified rating of the SPDs maximum discharge or impulse current. Upon reaching end-of-life, a correctly designed SPD will safely disconnect itself from the power supply. Such disconnection usually goes unnoticed since the indicator light is located directly on the SPD, which may not be frequently inspected due to remote location.
With Raycap's SPD life status indication devices it is easy for users to receive information about a failed SPD device immediately, or more importantly, to get a warning when a SPD is nearing its end-of-life. With these devices installed, power supply network operators know when to replace their SPD protection, which is just as important as having surge protection installed in the first place.
In large photovoltaic (PV) installations many PV panels are connected into strings which are in turn connected in parallel before being fed to the inverter. Such an arrangement means that strings which are not operating at maximum efficiency often go unnoticed. Raycap’s SMART string monitoring device, ProSMS 8, is designed to monitor eight strings individually and provide comparative analysis via advanced real-time onboard functions such as energy calculations and minimum/maximum values. Due to the exposed nature of such PV systems, the ProSMS also incorporates onboard surge protection and a lightning counter.
Averaging electrical current and voltage for any desired readout period helps PV operators more effectively manage their plant's operation and drastically reduce costs. Such systems also help provide an overall visibility to the complete PV plant operation, and help manage preventative maintenance and avoid loss of efficiency and costly downtime.

ProALARM
ProALARM is a failure indication device that informs a user of the need to replace a failed SPD. It can be quickly and easily installed next to the SPD on the same rail, and by making connection between the RC contacts of the SPD and the unit.
If failure of the SPD occurs, the user is informed by a loud audible beeping sound and the illumination of a red LED.
The user is able to acknowledge this event by the press of a button; this will silence the audible sound, but leave the LED illuminated until the SPD has been replaced.
