Universal measuring instrument LINETRAXX® PEM353

voltageACfrequency

• Numerous measured quantities (see features/functions) • Power Quality Monitoring • Limit value monitoring (setpoints) with alarm forwarding • Energy and power measurement with storage and Time of Use • Configurable start page with 4 measured quantities • N conductor measurement and monitoring (PEM353-N only) The digital universal measuring device PEM353 is used to record and display measured quantities of an electricity supply network, and make them available via the communication interface. The range of measurements extends from voltages and currents to power and energy meters to measured quantities of the voltage quality, such as THD and the individual harmonics up to the 31st order. The PEM353 is suitable for use in 2-, 3- and 4-wire systems and in their respective versions as TN, TT and IT systems. This allows monitoring single and polyphase systems. With its standardised dimensions of 96 x 96 mm, the device is intended for front panel mounting. 1. Measurement of electrical quantities such as – Phase voltages (individually + Σ) UL1, UL2, UL3 in V – Line-to-line voltages (individually + Σ) UL1L2, UL2L3, UL3L1 in V – Phase currents (individually + Σ) I1, I2, I3 in A – Neutral current In (calculated) in A, I4 (measured, PEM353-N only) in A – Residual current Ir (calculated, PEM353-N only) in A – Frequency f in Hz – Power per phase conductor (individually + Σ) P in kW, Q in kvar, S in kVA – Displacement factor (individually + Σ) cos (φ) – Power factor (individually + Σ) λ – Active and reactive energy import (individually + Σ) in kWh, kvarh – Active and reactive energy export (individually + Σ) in kWh, kvarh – Voltage phase angle (LN or LL, individually) in °
