RP-800T Transformer Protection

The RP-800T is suitable for protection of transformers up to 66kV controlled by circuit breakers, 10kV (6kV) / 0.4kv distribution transformers and 66kV low-capacity step-down transformers. It is especially suitable for power system, power distribution of factories and power distribution protection measurement and control of buildings. It can not only be centralized in a screen, but also can be installed in the switchgear directly. Therefore, it fully supports the power distribution automation system.

Features:

1.The case of the device is made of aluminum alloy. It has closed process, internal double shielding, anti-vibration and anti-interference, so it can adapt to many harsh environments.

2.The latest integrated circuit and high-performance 32-bit embedded digital signal processor constitutes a compact and efficient data acquisition and processing system. The integrated design of software and hardware makes the system extremely stable and reliable.

3.The hardware system is expandable; the module category is few and the function is powerful. The internal structure adopts metal connector module. The CPU adopts the four-layer board technology, which can effectively prevent the impact of intermittent pulse interference and the lightning surge.

4.Recording 64 times of protection events with time, and power fail protection included. The device can store three sets of fixed values, which is convenient to modify and switch.

5.Open - in and open - out are separated by two - light couplers, and it enhances the anti-interference ability of the device.

6.The device is AC/DC available. It will not stop working and protecting due to DC system failure. Devices at intervals including relay protection functions are relatively independent and communicate via Internet RS485.

7.The circuit breaker operating circuit is suitable for all kinds of circuit breaker control, which is convenient for substation reconstruction.
