DPT-100EC2(C3) type microprocessor based transformer protection and monitoring device is applies to the protection and monitoring of station or grounding transformers in systems with the neutral point and those grounded via an arc suppression coil or resistor with voltage ratings of 66kV and below.
Protection Function 1、Instantaneous protection(with compound voltage locking ) 2、Definite-time over-current protection (with compound voltage locking)，Inverse time over-current protection 3、Overload protection 4、Definite-time negative sequence over-current protection，Inverse time negative sequence over-current protection 5、Zero sequence over-current protection of high-voltage side 6、Definite-time zero sequence over-current protection and inverse time zero sequence over-current protection of low-voltage side 7、Low voltage protection ( under-voltage protection) 8、FC fused protection and blocking 9、Non-electric quantity protection、Process Interlock Protection 10、PT Break Judgment 11、CT Break Judgment Ordering instructions Provide the following upon ordering: 1. Name, model and quantity of the device. Please specify any special requirement differs from our standard product. 2. Voltage class. The operating power supply for any device is intended for both AC and DC purposes, with 110V and 220V inputs; the 220V version will be provided unless otherwise specified. 3. Communication port: The device standard communication configure is a single 485. If needs dual RS485 network which shall be specified. 4. Ratings of key parameters For a protector, provide the nominal rated current (1Aor5A) For a device with the zero sequence current protection function in a low-current ground system, provide the rated zero sequence current (0.2Aor0.02A) 5. Term and place of delivery, means of transport 6. Other terms shall be negotiated. |
