Gongyuan’s solutions start from your system, not from a product list. Tell us where the risk is, such as a charging pile, a battery cabinet, a PV string or a rail DC bus, and we recommend where to monitor, how to connect the alarm and which insulation monitoring device fits.
1. Risk scenario: Insulation degradation from moisture, connector wear or cable damage in the charging pile and vehicle path.
2. Monitoring approach: Monitor the DC output during charging, with relay alarm to stop or limit the session.
1. Risk scenario: Condensation, coolant leaks or damaged insulation inside battery cabinets on high-voltage platforms.
2. Monitoring approach: Continuous insulation resistance monitoring on the DC bus with early-warning threshold before a hard fault.
1. Risk scenario: Ageing cables, UV, rain and dust reducing insulation on strings and DC bus.
2. Monitoring approach: Monitor the DC side of the inverter or combiner to catch a first fault before it becomes a short circuit.
1. Risk scenario: Vibration, dust and humidity in auxiliary and traction-related floating systems.
2. Monitoring approach: Continuous monitoring with relay alarm to the SCADA or control cabinet.
Before ordering, prepare: system voltage and AC/DC type, single or multi-circuit, alarm threshold needed, communication protocol (relay, RS485/Modbus, CAN), installation environment, certification required (TUV/CE).
Insulation monitoring helps teams detect degradation before it becomes a safety risk, especially in floating DC and new energy systems.
DC insulation detection supports uptime, preventive maintenance, and safer operation in PV, storage, and DC grid projects.
