Measurement of power factor in AC system on L.T. Circuits having higher current load without interrupting circuit. SINGLE PHASE CIRCUITS :Connect potential between Neutral and line and clamp over 'Line' cable The instrument will read the power factor directly. THREE PHASE CIRCUITS: (4 Wires System) Balanced Loads :Measure as in '1' above in any of the phase. The instrument will read the power factor directly. Unbalanced Loads Measure as in '1' above in each of the three phases. Power factor is the algebraic mean of the individual readings of the three phases. THREE PHASE CIRCUITS: (3 Wires Systems) Derive a Neutral with the help of a Neutral Box and measure as in '2' above.

Type CIE-5000 PI is a universal, Multi-purpose instrument for checking insulation and conductance during simulated operating conditions in high tension electrical and electronic fields. It is ideally useful for the electrical maintenance of Rotating plant machinery, Distribution networks, Communication cable, Insulators and servicing of Control and switching equipments, transformers and industrial installations. Di-electric Absorption test requires the voltage to be applied for several minutes. Operating an instrument under motor power allows this to be done easily. The high sensitivity of the instrument enables sensible reading to be obtained from such polarization index tests. (Polarisation Index = Resistance after 10 min./Resistance after 1 min.) It is a versatile mains operated insulation tester which is recommended for every electrical engineer. The CIE -5000PI is a smart microprocessor based 5KV Insulation Tester and analyser besides the conventional measurement of Insulation resistance upto 100.0G Ohm. It’s advance features allow one to automatically measure both the polarization Index and Dielectric absorption ratio, thus significantly simplifying the testing of transformers and motors. The Insulation Tester is a mains (230V AC , 50-60Hz) operated Insulation Tester and analyser. The test voltage may be chosen in between 1KV,2.5KV and 5KV. Due to its measurement principal (actual voltage and current readings) the accuracy of resistance measurement is not affected by any test voltage error. The built in chronometer automatically counts the elapsed time since the start of the measurement and shown over display by which user can easily understand the actual condition of the insulation testing (e.g. in DAR Mode or in PI mode or in IR mode)The measured values all are automatically hold over display until the instrument restart or off. The Test Voltage shown over-display at the time of measurement. SALIENT FEATURES High Voltage Out Put Indicator 16X2 Jambo LCD Display. Start/Stop Button KV Selection Switch (1KV, 2.5KV, 5KV) Mode Selection Switch (IR, DAR, PI) Terminals (LINE, EARTH, GUARD) Power Switch (BACK PANEL)
