ABB SPAE010 is a high impedance protective relay with the following features and functions:

High impedance brake relay: SPAE010 avoids misoperation due to current transformer (CT) saturation.

Fast response: The operation time is approximately 15ms (excluding the auxiliary trip outlet relay), ensuring a rapid response in the event of a failure.

High sensitivity: A current transformer with a primary side action current is generally about 2%, showing its high sensitivity.

Stability: In the case of failure outside the area, even if the current transformer is saturated, it can be reliable without misoperation.

Working principle: SPAE010 is mainly used in power systems to identify fault types such as overload, short circuit and so on by measuring the phase difference between power supply voltage and current. When a fault is detected, the relay quickly cuts power to protect the power equipment.

Application scenario: SPAE010 is widely used in the protection of various power equipment to ensure the safe and stable operation of the power system.

In addition, SPAE010 and SPAE011 are differential current ground fault protection relays with the same function, the only difference between them is that the auxiliary supply voltage range is different. The auxiliary supply voltage range for the SPAE010 is 80-265 V ac, while the SPAE011 is 18-80 V dc. SPAE relays are used for ground fault protection of transformers, motors and generators, with built-in stabilizing resistors required, short overall operating time and high stability, and strong immunity to all types of mechanical and electrical interference.
