Overhead Short Circuit Fault Indicator

Description
The type HYI overhead short circuit fault indicators are designed to indicate the short circuit fault and identify locations. They are used in cable and overhead power lines up to 35kV. These fault indicators meet the requirements of various environmental conditions. By virtue of the minimum power consumption, they are supposed to be eco-friendly with merits like long life span and accurate indication. Their accurate fault indication enables the operator to identify the fault sections easily, and isolate them in time. As a result, it shortens the range and time of power outage, and increase the reliability of power supply. HYI short circuit fault indicators can be classified into two groups, namely the cable type and overhead type. The cable type is used in pad-mounted transformer, switchgear, power cable connection pillar and etc, and the overhead type the outdoor overhead power lines.

Features and Functions
1. This overhead short circuit fault indicator can provide accurate indication with power anti-jamming.
2. Adaptive trip and logic inrush restraint.
3. It has low power consumption and a long life span of 20 years. It is eco-friendly.
4. With the design of dormant function, this fault indicator will be in its dormancy stage when system is running smoothly.
5. Its outer case is made of toughened solid polymer, which enhances its corrosion resistance and elongates the durability.
6. The LED display of our overhead short circuit fault indicator is clear under both daytime and night conditions.
7. It supports current reset and automatic time reset.
8. It is immune to load changes.
Application
CEE overhead short circuit fault indicators offer three basic types: cable short circuit fault indicator, overhead short circuit fault indicator and earth and short circuit fault indicator. The cable type is used in pad-mounted transformer, switchgear power cable connection pillar and etc, and the overhead type is used in outdoor overhead power lines.
