The RIS2 protection relay is a safety detector for distribution transformers. It is an essential accessory for protecting your oil transformer. It continuously monitors pressure, temperature, oil level and gassing conditions. Description The transformer is an essential link in the electricity distribution network. In the event of a transformer failure (major overload, internal damage, etc.), the network upstream and downstream of the transformer must be protected by monitoring devices (alarm/shutdown) built into the protection relays. These may be of the DGPT2 (Gas, Pressure and Temperature Detection Relay), DMCR (Detection, Measurement and Control Relay) or RIS2 (Integrated Safety Relay) type. The RIS2 safety detector is the essential accessory for protecting your oil transformer, to ensure that it operates correctly. It consists of a robust plastic body, waterproof and resistant to extreme climates, with a series of instruments that constantly monitor operating conditions. Like the DGPT2 or DMCR, the RIS2 monitors tank pressure from 100 to 500 mbar. This function measures the transformer’s internal pressure. When it exceeds a predefined level, the alarm circuit is triggered. Thanks to its built-in thermometer, this relay indicates the internal oil temperature and the maximum temperature reached in the event of an internal fault or overheating. It contains two thermostatic switches, “T2” (ALARM) and “T1” (OFF), which trip at a preset temperature. The visual sensor indicates any change in the gas or significant variation in the oil level. This is indicated by the position of the float between “MIN” and “MAX”. If there is a significant change in oil or gas level,
