Multifunction Power Meter Manufacturers In protection and control engineering, a multifunction power meter is never just a panel instrument for displaying voltage and current. In real secondary systems, it serves as a data acquisition node for the primary system, an information source for control and supervision, and often a key interface for SCADA, energy management, fault annunciation, harmonic analysis, and remote communications. That is why selecting a multifunction meter

Why AC Dual-Source Transfer Is Harder Than It Looks In many substations, industrial plants, and rail facilities, the “information brain” of the site still runs on AC: station control servers and engineering workstations industrial switches and firewalls DCS/PLC controllers remote terminal and gateway equipment A brief disturbance on the incoming AC feeder, or one maintenance pull of a plug-in breaker, can be enough to black out an entire panel. Screens go dark, communication

Intermediate relays rarely take center stage in substation design, yet they directly determine wiring quality, maintainability, EMC robustness, and long-term reliability in both primary and secondary circuits. For a complete overview of ODES relay and control products, visit www.odes-electric.com .

One integrated control module that replaces fragile “contactor + timer” circuits with deterministic protection and programmable logic A controller designed to eliminate cross-wiring, unify protection logic, and standardize GIS motor circuitry In many GIS isolator mechanisms, wiring complexity has become a technical debt: scattered relays, parallel signal bundles, multi-row terminal blocks, and heavy door wiring add effort, delay commissioning, and introduce long-term maintena

Modern utilities, especially in fast-pace operational environments, are moving toward standardized, modular, and quickly replaceable control architectures. Visit www.odes-electric.com to explore how ODES is supporting this transition with integrated HV motor-control solutions. In many high-voltage switchgear projects, energy-storage motor circuits are still stitched together with timers, thermal relays, and contactors . They function, but they don’t scale. Any modificat

In most primary high-voltage switchgear, energy storage motor circuits are still pieced together with timers, contactors, and thermal relays . These discrete setups “work,” but they are hard to modify, lack full protection visibility, and depend heavily on individual experience. The ODES PSME309 Energy Storage Controller changes that — transforming “handcrafted wiring logic” into data-driven, parameter-based control . It integrates protection, configuration, and m

In most substations, temperature data for transformers still hides behind the control room screens. Oil, core, and winding temperatures — the “three thermometers” that reveal a transformer’s true condition — are often invisible at the equipment itself. Operators walk back and forth between panels and SCADA terminals just to confirm if things are running hot or cold. In regions like Inner Mongolia, Gansu, and Xinjiang , where on-site staffing is essential, maintenance teams

In many primary-equipment projects, energy-storage motor control circuits are still built from discrete devices — a relay here, a contactor there, maybe a timer or a thermal overload. They work… until the logic changes, the power system evolves, or the environment pushes the limits of reliability. At that point, every adjustment feels like dismantling a house. The ODES integrated energy-storage control platform replaces this fragmented approach with a unified, param

Motor control in medium-voltage ring main units (RMUs) is often underestimated. In reality, it’s not just about “making the motor turn.” For engineers, what matters is stable positioning, safe interlocking, quick diagnostics , and the ability to perform reliably under high EMI, long-cable, or harsh environmental conditions. This is the engineering philosophy behind the ODES PCM965 Series , a unified three-branch platform developed to cover C-cabinet (load switch), F

Modern gas-insulated switchgear (GIS) relies on more than just motor actuation — it demands stability, precision, and diagnostic intelligence under harsh field conditions. Engineers face daily challenges such as unreliable positioning, misoperation, wiring complexity, and poor fault visibility. The PCM Three-Position Programmable Motor Controller from ODES is purpose-built to solve these issues through an integrated, standardized, and EMC-hardened design . Learn mor

In today’s global power infrastructure market, fault alarm systems must not only react quickly but also present information with absolute clarity. Yet requirements for alarm color indication vary widely between countries: 🇹🇭 Thailand: two-color indication standard 🇯🇴 Jordan: three-color requirement 🇸🇦 Saudi Arabia: six-color display for multiple alarm levels Many suppliers struggle to balance these regional differences within one design.

Complex wiring doesn’t have to be the price of functionality. Discover how ODES is making GIS alarm systems lighter and smarter at www.odes-electric.com The Problem: Cable Clutter in Modern GIS Panels In many GIS high-voltage switchgear projects, door-control wiring —the bundles of signal cables running from the cabinet body to the front door—remains a persistent challenge. It’s common to see 30 or more wires , each several meters long, running through the door frame li

In secondary systems such as protection and control , station communication , and industrial automation , DC switch-mode power supplies are standard. Yet engineers often encounter an odd problem: the load power is below the supply’s rating , but the unit still trips into overcurrent or overload protection at startup. The issue isn’t always poor quality—it’s usually poor matching . Subtle transient conditions can create “invisible overloads.” This article explains th

The Challenge of DC Signal Diversity Direct-current measurement and control are essential to every power and industrial automation system, yet DC signals rarely come in a single form. In substations, 110/220 VDC control power must be monitored accurately to ensure dependable tripping and closing operations. In industrial environments, PLCs and DCSs typically accept only standardized analog inputs such as 4–20 mA or 0–5 V , while field devices often output unscal

Beyond Safe Operation — What Defines a Good Test Switch In protection and control systems built to ANSI standards, performance is not just about “safe switching.” Engineers must also evaluate configuration flexibility, installation practicality, and environmental endurance . The TSBA Series ANSI-Type Test Switch from ODES was developed with these parameters in mind. It provides modular configuration options, robust electrical ratings, and accessories tailored for modern

Re-engineering Safety in Relay Testing In ANSI-based protection systems, commissioning teams must achieve two goals simultaneously: guarantee zero CT open-circuit risk and complete isolation, measurement, and verification within limited panel space . A well-designed ANSI-type test switch and plug assembly transforms these complex tasks into a single, repeatable operation. The ODES TSBA Series Test Switch from ODES is purpose-built for this environment. It inco
