Resistance Meters Explained: Choosing the Right Micro Ohm & Contact Resistance Meter Resistance measurement is a critical part of electrical testing, maintenance, and quality control. From low-resistance winding checks to high-current circuit breaker testing, selecting the right Resistance Meter ensures accurate diagnostics, safety, and long equipment life. This guide explains different types of resistance meters, their applications, and how to choose the right instrument based on current rating, accuracy, and testing environment. What Is a Resistance Meter? 200A contact resistance meter used for circuit breaker maintenance A Resistance Meter is an electrical test instrument used to measure resistance values ranging from milliohms (mΩ) to micro-ohms (µΩ). These meters are essential for detecting: Loose or deteriorated electrical connections Overheating risks in joints and terminals Winding resistance imbalance Contact wear in switches and circuit breakers Types ...

Why 3-Phase Transformer Turns Ratio Testing Is Critical Before Commissioning 3 Phase Transformer Turns Ratio Testing Transformer commissioning is incomplete without Turns Ratio Testing (TTR) . For medium and large power transformers, 3-phase transformer turns ratio testing plays a vital role in ensuring winding correctness, vector group integrity, and operational safety. What Is Transformer Turns Ratio Testing? Transformer Turns Ratio Testing verifies the ratio between high-voltage (HV) and low-voltage (LV) windings. Any deviation from the designed ratio can indicate: Incorrect tap changer connections Shorted or open windings Manufacturing defects Improper repairs or rewinding errors This test is mandatory as per IEC and IS standards during manufacturing, installation, repair, and final commissioning. Why 3-Phase Turns Ratio Testing Is Essential Traditional single-phase ratio testing requires multiple reconnections, increasing testing time and chances of ...

What Is an I/P Converter? How 4–20 mA Controls Pneumatic Valves Industrial Current to Pressure Converter – Fairchild TD6000 Series In modern industrial automation, electronic controllers like PLCs and DCS systems often need to operate pneumatic control valves. This is where an I/P Converter — also called a Current to Pressure Converter — plays a critical role. What Is an I/P Converter? An I/P Converter (Current-to-Pressure Converter) is an electro-pneumatic device that converts an electrical control signal, typically 4–20 mA , into a proportional pneumatic output such as 3–15 PSI . This conversion allows electronic control systems to accurately regulate pneumatically actuated control valves , dampers, and positioning devices. Why 4–20 mA and 3–15 PSI Are Industry Standards The 4–20 mA current loop is widely used in industrial environments because it is resistant to electrical noise and allows fault detection. Similarly, 3–15 PSI is the most common pneumatic control ...
