HRMM-300-11E

HRMM-300-11E Introduction

The HRMM-300-11E is a type of medium voltage relay manufactured by the Wuxi Power Technology Company. It is used to protect the electrical system from adverse conditions and to control and monitor the operation of the system. It can also be used for automatic and manual coordination and synchronization of switched pieces of equipment. This type of relay is used in a variety of applications, including low-voltage distribution systems, motor control systems, and industrial automation systems.

Applications

The HRMM-300-11E is suitable for applications where medium voltage relay protection is needed. It can be used in low-voltage distribution systems, motor control systems, and industrial automation systems. It can also be used for automatic and manual coordination and synchronization of switched pieces of equipment. It can provide protection against overload, short circuit, and other fault conditions. It can also be used for monitoring and controlling the operation of the system, such as current monitoring, voltage monitoring, and thermal protection.

Working Principle

The HRMM-300-11E operates on the principle of differential protection, which is used to measure the difference between two voltage or current signals to detect any faults in the system. When the differences between two signals exceed the specified value, the relay trips and disconnects the circuit for safety. Other protective functions provided by the relay include thermal protection, over-current protection, short-circuit protection, and reverse-power protection.

The HRMM-300-11E can be used for monitoring and controlling the operation of the system. It can measure the actual voltage and current values and compare them against the set values. If there are any discrepancies, the relay will trip and disconnect the circuit for safety. It can also be used for monitoring the temperature of the system, which is important for protecting against overheating.

The HRMM-300-11E can also be used for controlling the operation of the system. For example, it can be used to control the power input and output of the system. It can be used for automatic and manual coordination and synchronization of switched pieces of equipment. It can also be used for load shedding of excess load in the system.
