Product descriptions from the supplier
The GRI8-06 series is a multifunctional current monitoring relay that uses isolated current transformer technology and supports through installation and external transformer expansion. Its compact design (with a width of only 18mm) is compatible with standard 35mm card rails, providing dual mode monitoring of overcurrent/undercurrent. The working power supply covers a wide voltage range of AC/DC 24~240V, suitable for mixed AC/DC scenarios.
GRI8-06 series current relay product features:
1. Create a core structure
The direct wiring installation design completely eliminates the need for traditional current relays to disconnect the main circuit, improves installation efficiency, and reduces the risk of system shutdown.
2. Intelligent mode switching function
Quickly set the overcurrent/undercurrent monitoring mode through the panel knob, without the need for professional tools to complete parameter configuration, simplifying the operation and maintenance process.
3. AC/DC global detection capability
Provide AC/DC compatible specification options to achieve seamless adaptation to different power systems and enhance equipment versatility.
4. Scalable monitoring range
The built-in isolation current transformer also supports external transformers, and the monitoring current range can be extended to several thousand amperes, meeting the needs of high current scenarios.
5. Wide range power supply adaptability
AC/DC 24~240V wide voltage input design effectively addresses voltage fluctuations in industrial sites.
6. Dual channel relay output
Equipped with two independent relay contacts (1CO+1NO), it can synchronously trigger alarms and control commands, improving system linkage efficiency.
7. Visual status indication
The high brightness LED indicator light displays the real-time working status and fault type of the relay, achieving fast fault location.
8. Compact design
The 18mm ultra narrow body, combined with 35mm standard card rail installation, provides an efficient space solution for high-density electrical cabinets.

On-Line Testing for Surge Arresters Below 110kV: Safe and EfficientAn On-Line Testing Method for Surge Arresters at 110kV and BelowIn power systems, surge arresters are critical components that protect equipment from lightning overvoltage. For installations at 110kV and below—such as 35kV or 10kV substations—an on-line testing method effectively avoids the economic losses associated with power outages. The core of this method lies in using online monitoring technology to evaluate arrester performance without interrupting system operation.The test principle is bOliver Watts10/23/2025 -
Why Upgrade to Maintenance-Free Transformer Breathers?Maintenance-Free Moisture Absorption Technology for Oil-Immersed TransformersIn traditional oil-filled transformers, the temperature control system causes thermal expansion and contraction of insulating oil, requiring the sealing gel chamber to absorb significant moisture from the air above the oil surface. The frequency of manual silica gel replacement during patrols directly impacts equipment safety—delayed replacement can easily lead to oil degradation.

Why Does MVDC Grounding Cause System Faults?Analysis and Handling of DC System Grounding Faults in SubstationsWhen a DC system grounding fault occurs, it can be classified as single-point grounding, multi-point grounding, loop grounding, or reduced insulation. Single-point grounding is further divided into positive-pole and negative-pole grounding. Positive-pole grounding may cause misoperation of protection and automatic devices, while negative-pole grounding may lead to failure to operate (e.g., relay protection or tripping devices).

Why Can't VT Be Shorted & CT Be Opened? ExplainedWe all know that a voltage transformer (VT) must never operate short-circuited, while a current transformer (CT) must never operate open-circuited. Short-circuiting a VT or opening the circuit of a CT will damage the transformer or create hazardous conditions.From a theoretical standpoint, both VTs and CTs are transformers; the difference lies in the parameters they are designed to measure. So why, despite being fundamentally the same type of device, is one prohibited from short-circuit operatioEcho10/22/2025
