Other instruments / adapters / accessories Other instruments / adapters / accessories MI 3144 EURO Z 800 V The MI 3144 Euro Z 800 V is a multifunctional, portable battery (Li-ion) or mains powered test instrument with excellent IP protection: IP65 (case closed), IP54 (case opened). It can be controlled via an Android app aMESM , MI 3152, MI 3152H, MI 3155 or MI 3325. The MI 3144 Euro Z 800 V is intended for measuring the effectiveness of automatic trip out protection in case of faults in transformers and other HV equipment. With its high precision line and loop impedance measurements on AC and DC circuits, high current dR 300A loop and line measurements for testing of partial currents and partial voltage drops, it is ideal for testing in industrial settings. It also supports contact voltage measurements, ELR electrical leakage relay testing with fault current injection, trip-out time measurement and DC source, line, battery and accumulator measurements. • High precision 4-wire 300 A Z Line and Z Loop Impedance Tester; • High range impedance measurements in 800 V / 16 ... 420 Hz AC networks; • DC source & line resistance measurements in 3 ... 260 V DC networks; • High current dR 300 A 4-wire Partial Voltage drops and Current's Path Resistances; • Earth Leakage Relay (ELR) trip-out testing time and current; • ELR supported types AC, A, B; • Ground fault analysis with Contact, Touch and Step voltage; • Floating voltmeter for partial contact results; • One-clamp high current grounding method with clamps (flex & iron); • Selectable test load (16.6 % to 100 %); • Improved thermal performance; • Portable battery (Li-ion) or mains powered test instrument; • IP protection: IP65 (case closed), IP54 (case opened); • CAT IV 600 V (3000 m) safety category; • Bluetooth communication; • Black box design (remote-controlled via an Android device). • Live Power Transformer Hi Precision 4-wire 300 A Z Line / Loop Impedance testing; • Partial Voltage Drops and Partial Clamp Current’s Path resistance measurements; • Airports High Frequency Band 16 ... 420 Hz Installation Impedances testing; • DC Networks’ and Power Sources’ Line and Loop Resistances; • Flex & iron one-clamp high current dR 300 A Grounding method for Lightning systems; • High Current dR 300 A Integrity of Grounding; system with Flex and Iron One-Clamp method • ELR (MRCD) trip-out Current and trip-out time testing; • Earth Potentials by method of measuring Step, Touch and Transfer voltages; • Automatic trip-out protection evaluation in case of faults in transformers, generators, turbines, contactors, distribution boards and switchyards whenever energetic loads and sources of protection exceed 200 A; • Power transformer and motor winding measurement; • High accuracy battery resistance testing; • Ground grid integrity testing by measuring the resistance between two risers; • Contact voltage measurement; • High current injection ground fault simulation; • One clamp earth resistance testing.
