TG30S Phase Failure Phase Sequence Protect Relay TL-2238

First, the protection characteristics Characteristics of protection-1. Dynamic phase loss, static phase loss protection: refers to the protected device in the running state or non-operating state, any phase phase failure occurred. The indicator light is: red light is on and priority;2. Phase protection: to prevent L1, L2, L3 three-phase AC power supply phase sequence of a protection measure. Instant action. The light is in the form of:3. Voltage unbalance protection: refers to the three-phase voltage imbalance will affect the safe operation of a voltage imbalance protection. When the voltage imbalance is higher than 8%. The indicator light is in the form of: the missing red light is on and priority;4. Delay protection: fault occurs when the monitor delay 1 2 seconds after the action, the relay release;Second, the performance characteristics of performance-1. The protection function of the monitor is not affected by the current or current of the line or load, the impact current, the unbalanced current and the load nature. Able to full performance, the whole climate long-term work. Power consumption is not greater than 2W;2. There is no requirement for motor wiring when used for motor protection;3. This product complies with GB / T 14048.1-2000, GB14048.5-2001 eqv IEC60947-1: 1999; -4. EMC of this product conforms to the radio interference characteristic measurement method and allowable value of GB4343-1995;Third, the characteristics of working characteristics of working-1.L1, L2, L3 three-phase wiring is correct, the monitor green light, relay pull; if the phase sequence error, monitor yellow light, as long as the exchange of L1, L2, L3 three phase of any two phases, the monitor Can identify the phase sequence and work properly. When the protected device is working properly after the yellow light, the relay does not pull, should be regarded as outside the l
