Once installed, it monitors power quality, electrical parameters, environmental conditions and other critical facility parameters without the monitoring gaps associated with temporary field surveys.<\/p>\n<p class=\"isSelectedEnd\">The system is suitable for medical equipment, industrial facilities, data centers, renewable-energy installations, telecommunications infrastructure, IT facilities and building management systems.<\/p>\n<h2>Dual Isolated Power Quality Channels<\/h2>\n<p class=\"isSelectedEnd\">Inspector INS4-1 provides two isolated power-quality channels. Each channel includes five voltage inputs and five current inputs, allowing simultaneous monitoring of two independent electrical sources or feeders.<\/p>\n<p class=\"isSelectedEnd\">The analyzer supports:<\/p>\n<ul data-spread=\"false\">\n<li>Single-phase, two-wire systems<\/li>\n<li>Three-phase, three-wire delta systems<\/li>\n<li>Three-phase, four-wire star systems<\/li>\n<li>Simultaneous monitoring of utility and UPS output<\/li>\n<li>Monitoring of two independent feeders<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Voltage measurements cover 0 to 1000 VRMS with 0.1 VRMS resolution and \u00b10.5% accuracy. Current measurements cover 0 to 1000 A with 0.1 A resolution and \u00b12% accuracy.<\/p>\n<p class=\"isSelectedEnd\">A 24-bit ADC and a sampling rate of 32 KSPS for each input provide detailed acquisition of electrical waveforms and power-quality events.<\/p>\n<h2>Comprehensive Electrical Measurements<\/h2>\n<p class=\"isSelectedEnd\">This stationary power quality analyzer measures and records:<\/p>\n<ul data-spread=\"false\">\n<li>RMS line-to-line and line-to-neutral voltage<\/li>\n<li>RMS current and crest factor<\/li>\n<li>Active, reactive and apparent power<\/li>\n<li>True, displacement and demand power factor<\/li>\n<li>Active, reactive and apparent energy<\/li>\n<li>Voltage and current total harmonic distortion<\/li>\n<li>Harmonics and interharmonics<\/li>\n<li>Voltage and current unbalance<\/li>\n<li>Voltage and current waveform peaks<\/li>\n<li>Frequency and voltage flicker<\/li>\n<li>K-Factor and phase-sequence detection<\/li>\n<li>Power demand values<\/li>\n<\/ul>\n<h2>Electrical Event Detection<\/h2>\n<p class=\"isSelectedEnd\">Inspector INS4-1 detects electrical disturbances according to <a href=\"https:\/\/webstore.iec.ch\/en\/publication\/71611\">IEC 61000-4-30 power-quality measurement classifications<\/a>.<\/p>\n<p class=\"isSelectedEnd\">Detected events include:<\/p>\n<ul data-spread=\"false\">\n<li>Voltage dips and swells<\/li>\n<li>Voltage interruptions<\/li>\n<li>Voltage transients<\/li>\n<li>Rapid voltage changes<\/li>\n<li>Frequency variations<\/li>\n<li>Inrush current<\/li>\n<li>Total harmonic distortion<\/li>\n<li>Phase-sequence events<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The system captures the beginning and end of each event, including five cycles before and five cycles after the disturbance. This helps maintenance teams investigate incidents and identify whether problems originate upstream or downstream.<\/p>\n<h2>Environmental and Grounding Monitoring<\/h2>\n<p class=\"isSelectedEnd\">Inspector INS4-1 combines electrical analysis with environmental monitoring. The standard system supports three external temperature sensors covering 0\u00b0C to 85\u00b0C with \u00b10.5\u00b0C accuracy.<\/p>\n<p class=\"isSelectedEnd\">Additional monitoring capabilities include:<\/p>\n<ul data-spread=\"false\">\n<li>Earth current measurement from 0 to 10 A<\/li>\n<li>Earth resistance measurement up to 200 \u03a9<\/li>\n<li>Tripping and non-tripping grounding measurement<\/li>\n<li>Two 4-20 mA analog sensor inputs<\/li>\n<li>Optional humidity and temperature sensors<\/li>\n<li>Pressure, flow and process sensor integration<\/li>\n<\/ul>\n<h2>Expandable Monitoring Modules<\/h2>\n<p class=\"isSelectedEnd\">Inspector INS4-1 can be expanded with specialized modules:<\/p>\n<ul data-spread=\"false\">\n<li>THPAQ R1: Monitors temperature, humidity, barometric pressure, CO\u2082, TVOC, NOx, particulate matter, air quality and vibration.<\/li>\n<li>THPAQ R2: Monitors temperature, relative humidity and barometric pressure.<\/li>\n<li>MMU: Provides non-invasive current monitoring for motors, pumps and compressors using split-core current transformers.<\/li>\n<li>SIB: Connects up to eight 4-20 mA industrial sensors per module, with support for cascading multiple units.<\/li>\n<li>SMU: Measures ambient hydrogen sulfide and sulfur dioxide in industrial environments.<\/li>\n<\/ul>\n<h2>Communication and System Integration<\/h2>\n<p class=\"isSelectedEnd\">Inspector INS4-1 can integrate with monitoring, automation, SCADA and building management systems through:<\/p>\n<ul data-spread=\"false\">\n<li>HTTP and HTTPS<\/li>\n<li>Modbus<\/li>\n<li>BACnet<\/li>\n<li>IEC 61850<\/li>\n<li>DNP3<\/li>\n<li>MQTT<\/li>\n<li>SNMP<\/li>\n<li>IEC 62056<\/li>\n<li>Email notifications<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The unit includes two Gigabit Ethernet ports, six RS-485 ports, two USB 2.0 ports and one HDMI 2.0 port.<\/p>\n<h2>Key Features<\/h2>\n<ul data-spread=\"false\">\n<li>Continuous 24\/7 power-quality monitoring<\/li>\n<li>Two isolated power-quality channels<\/li>\n<li>Five voltage and five current inputs per channel<\/li>\n<li>24-bit measurement resolution<\/li>\n<li>32 KSPS sampling rate for each input<\/li>\n<li>Voltage measurement up to 1000 VRMS<\/li>\n<li>Current measurement up to 1000 A<\/li>\n<li>Six-hour lithium-ion battery backup<\/li>\n<li>16 GB internal flash memory<\/li>\n<li>External 32 GB SD card expandable to 256 GB<\/li>\n<li>Industrial communication protocol support<\/li>\n<li>Environmental and grounding measurements<\/li>\n<li>Optional motor, air-quality and industrial sensor modules<\/li>\n<li>Operating temperature from 0\u00b0C to 50\u00b0C<\/li>\n<li>Indoor IPX1 enclosure<\/li>\n<\/ul>\n<h2>Standard Package Contents<\/h2>\n<p class=\"isSelectedEnd\">The standard Inspector INS4-1 package includes:<\/p>\n<ul data-spread=\"false\">\n<li>Inspector main unit<\/li>\n<li>Three external temperature sensors<\/li>\n<li>Motor Monitoring Unit<\/li>\n<li>Three 100 A split-core current coils<\/li>\n<li>THPAQ environmental and air-quality unit<\/li>\n<li>Voltage measurement cables<\/li>\n<li>Network and installation cables<\/li>\n<li>Delta and star connection cable<\/li>\n<li>10 A earth-current clamp<\/li>\n<li>Four 600 A current coils for three-phase and neutral measurement<\/li>\n<\/ul>\n<h2>\u0627\u0644\u062a\u0637\u0628\u064a\u0642\u0627\u062a<\/h2>\n<p class=\"isSelectedEnd\">Inspector INS4-1 is suitable for:<\/p>\n<ul data-spread=\"false\">\n<li>Hospitals and medical equipment<\/li>\n<li>Industrial production facilities<\/li>\n<li>Data centers and server rooms<\/li>\n<li>Renewable-energy installations<\/li>\n<li>Telecom infrastructure<\/li>\n<li>Building management systems<\/li>\n<li>UPS input and output comparison<\/li>\n<li>Pumps, motors, compressors and chillers<\/li>\n<li>Critical electrical distribution systems<\/li>\n<li>Preventive and predictive maintenance programs<\/li>\n<\/ul>\n<h2>Explore PowerWadi Power Quality Solutions<\/h2>\n<p class=\"isSelectedEnd\">\u00a0<a href=\"https:\/\/powerwadi.com\/ar\/download-center\/\">\u0645\u0631\u0643\u0632 \u062a\u062d\u0645\u064a\u0644 PowerWadi<\/a> for technical datasheets and product documentation.<\/p>\n<h2>Request a Quote<\/h2>\n<p>Need help selecting the correct current clamps, sensors or expansion modules? <a href=\"https:\/\/powerwadi.com\/ar\/contact-us\/\">\u062a\u0648\u0627\u0635\u0644 \u0645\u0639 PowerWadi<\/a> to discuss your monitoring requirements and request a quotation for Inspector INS4-1.<\/p>","protected":false},"excerpt":{"rendered":"<p class=\"text-base sm:text-lg text-gray-700 leading-relaxed\">Inspector INS4-1 is a stationary power quality analyzer built for continuous 24\/7 monitoring in mission-critical facilities.
