What is Motor Testing? Electrical maintenance programs are designed to enhance equipment reliability and uptime while reducing operational costs. Electric Motor Testing is often one of the first areas to be scaled back when cutting expenses. However, savvy companies recognize that neglecting proper maintenance programs can result in billions of dollars in lost revenue due to increased motor repair...
Fault record of Active Harmonic Filter A Fault Record of an Active Harmonic Filter (AHF) typically documents any issues, malfunctions, or performance anomalies that occur during its operation. This record is essential for troubleshooting, maintenance, and ensuring the reliability of the system. Key elements in a fault record might include: Key Elements of Fault Record Date and Time: When the fault...

They play key roles in power supply systems, signal processing, and energy storage. Their electrical properties directly affect circuit performance, efficiency, and reliability. Engineers and circuit designers must understand these properties to ensu...
In an era where industries face mounting pressure to balance operational efficiency with regulatory compliance, Active Harmonic Filters (AHFs) have emerged as a critical technology at the intersection of business strategy and energy policy. As nonlinear loads like data centers, electric vehicle chargers, and industrial automation proliferate, AHFs are no longer just an engineering soluti...
1. Current Transformer (CT) A Current Transformer is an instrument transformer used to measure alternating current (AC) by stepping down high currents to a lower, measurable value. Key Functions: Current Measurement: Steps down high primary current (e.g., 1000A) to a standardized secondary current (e.g., 5A or 1A) for meters and relays. Isolation: Provides galvanic isolation be...
Active Harmonic Filters (AHFs) are widely used in buildings to mitigate harmonic distortion caused by non-linear loads, ensuring power quality, energy efficiency, and compliance with standards like IEEE 519 and IEC 61000-3-6. Here are key applications of AHFs in buildings: 1. Office Buildings & Commercial Complexes Loads: LED lighting, VFDs (HVAC systems), elevators, UPS systems...
The 4 quadrants of reactive power refer to the different combinations of active (real) power (P) and reactive power (Q) flow in an AC electrical system. These quadrants are defined based on whether power is being generated or consumed and whether the system is supplying or absorbing reactive power. Four Quadrants of Reactive Power: The quadrants are categorized based on th...
