Electrical network analyzer PQM II

power qualityfor integrationmonitoring

The PQM II is an ideal choice when continuous monitoring of a three phase system is required. It provides metering for current, voltage, real and reactive power, energy use, cost of power, power factor and frequency. Programmable setpoints and 4 assignable output relays allow control functions to be added for specific applications. This includes basic alarm on over/under current or voltage, unbalance, demand based load shedding, and capacitor power factor correction control. More complex control is possible using the 4 switch inputs which also can be used for status such as breaker open/closed, flow information etc. New In Version 2.10: • Voltage Disturbance Recorder (VDR) to monitor voltage dips (voltage sags) and voltage spikes (voltage swells) with capacity for 500 sag/swell events. • DNP 3.0 Communications Protocol standard feature. Features and Benefits • Mounting Versatility • Keypad with large illuminated 40-character display • Any assignable output may be used to trigger an alarm • May be connected to DCA or SCADA systems • Flash upgradable • Compatible with MultiNet Serial to Ethernet Converter Applications • Metering of distribution feeders, transformers, generators, capacitor banks and motors • Medium and low voltage systems • Commercial, industrial, utility • Flexible control for demand load shedding, power factor, etc. • Power Quality analysis tool Protection and Control • A V W var VA varh Wh PF Hz unbalance • A W var VA demand • Load shedding • Power factor control • Pulse input totalizing Monitoring and Metering • Ia Ib Ic In • Va Vb Vc Vab Vbc Vca • V I unbalance • True PF crest and K factor • Hz W var VA • Wh varh VAh W cost • Demand: A W var VA
