Product Introduction

Digital lightning arrester leakage current meterIt is a new generation lightning arrester monitor developed based on the digital meter specifications of State Grid Smart Substation. Using a 3-digit electromagnetic counter display, the full current is designed with a wide temperature spontaneous OLED display screen, which is clearly visible in sunlight. The current detection adopts a new high-precision zero flux current sensor, which has higher accuracy than traditional pointer meters. The communication part adopts RS485 with optoelectronic isolation and Modbus communication protocol for digital meters. The power supply part also adopts electromagnetic isolation power supply, which can withstand ± 15KV voltage surge to ensure electrical safety. The stainless steel shell and full shell chassis design have a protection level of not less than IP65 and comply with the relevant requirements of JB/T 10492-2011.

Product features

1. Automatic monitoring function: It can periodically automatically monitor the full current, number of actions, and action time of the lightning arrester.

Wireless communication function. This function is mainly for the LoRa wireless communication function of the lightning arrester monitoring device. Upload the characteristic data of the lightning arrester to the station aggregation node device through LoRa communication, and complete the data upload every 5 minutes.

The LoRa communication of the device complies with the "Q/GDW 12020-2019 Transmission and Transformation Equipment IoT Micro Power Wireless Network Communication Protocol" and can be directly connected to the perception layer of the transmission and transformation IoT without the need for other configurations.

2. Local display function: The lightning arrester action count is displayed using a 3-digit electromagnetic counter. The full current is displayed on a scale (the scale range can be configured). The scale has a normal area (green), a caution area (yellow), and an alarm area (red).
