|1.Pinpoint of RMU
Ring main unit is one of the key electric equipment in power distribution network, excess heat on its inner cable connections is prone to cause oxidation, resulting in a substantial decline in lifespan of the cable, and even may also lead to catastrophic failures such as explosions, insulation breakdown, and power outage, which ultimately affecting the operation safety of the entire power network hence it is of great practical significance to monitoring the RMU temperature of cable joints.
Herch Opto creatively embedded the temperature probe into the insulation plug, once fit it into the T-connector, the probe will contact with the cable and get direct temperature reading of the cable joint.
