QPI-6LZ

QPI-6LZ is an advanced top-level protection relay, which is designed to protect medium/low voltage networks. The relay has exceptional accuracy, instantaneous protection, extended temperature range, high fault sender, reliable grounding discriminator and other features.

QPI-6LZ is widely used in power transformers, distribution systems, DC systems, wind power systems, solar power systems, street lighting systems, home lighting systems, industrial production systems, and other occasions. It is an ideal choice for power transmission and distribution applications.

The QPI-6LZ relay features a digital design that accurately detects faults, quickly reacts to overloads, and can detect a wide range of voltages and frequencies. It provides comprehensive protection, from over-voltage protection and under-voltage protection to short circuit protection, ground fault protection, over-current protection, over-temperature protection, and vibration protection.

The user can set the parameters of the QPI-6LZ and select the relays that meet the needs of the application field, such as voltage level, current limit, time delay, and other parameters. The user can also monitor the status of the power system through multiple parameters through the Local Operator Panel (LOP).

In addition to detecting and monitoring the system status, the QPI-6LZ can also provide self-diagnostics to simplify the fault analyzing and troubleshooting. For example, the relay can detect the source of the fault, detect the scheme status, monitor the power system, and provide the trajectory data for short circuit fault.

The QPI-6LZ is a reliable and easy-to-use protective device that can help to reduce the maintenance cost and improve the system reliability. Its compact size and modern design make it a perfect choice for applications in various sites.
