Acrel AM5SE-IS Anti-islanding Protection Relay for Renewable Energy EMS
General
AM5SE-IS anti-islanding protection device is mainly suitable for new energy grid-connected power supply systems such as 35kV, 10kV and low-voltage 380V photovoltaic power generation and gas power generation. When the island phenomenon occurs, the grid connection point can be quickly cut off, so that the station can be quickly separated from the grid side, ensuring the safety of the entire power station and related maintenance personnel.

FAQ of AM5 Middle Voltage Protection Relay
The protection device can set the CT and PT ratio through the fixed value menu. For example, the current transformer is 75/5 and the voltage transformer is 10/0.1, then the CT ratio is set to 15 and the PT ratio is set to 100.
AM5-F is suitable for line protection and transformer protection.No need to distinguish between models when placing orders
The voltage wiring mode and current wiring mode of the protection device can be set independently, and can be connected freely.
If the circuit breaker is equipped with anti-trip, the device does not must be equipped with anti-trip; if the circuit
breaker does not have anti-trip, you need to configure the AM5-FT anti-trip module. (If DC48V is selected as the
operating power supply, the anti-trip box is not optional, and the circuit breaker must be equipped with anti-trip
function; if you choose AC anti-trip, please note that AC and DC general anti-tripping)
Before ordering, it is recommended to consult related engineers, select the appropriate protection model,
and then fill in the corresponding selection table, and place the order after confirmation by the engineers.
