  • Selectable Insulation Monitor produced by DEIF company is used for supervision of the insulation resistance between an insulated voltage distribution network (IT network) and earth cable/safety cable. The instrument is applicable in conjunction with single phase networks and 3-phase networks with/without neutral for phase to phase voltages up to 690V AC. This type of insulation measurement is only carried out on AC networks where the neutral/star point of the generator or supply transformer is not earthed. An AC or DC auxiliary voltage is required for the in- strument. This may be selected independently of the monitored network, or the SIM-Q can be supplied by the monitored network; max. voltage for the supply is 480V. If the SIM-Q is supplied from a separate voltage source, the network can also be monitored in stand-by condition. Because of the measuring method used, the SIM-Q is able to measure the insulation correctly on an AC power network containing all kinds of loads, such as frequency converters (see the technical specifications for working frequency range), valves with rectifiers, thyristor controlled thrusters, switch mode power supplies, transformers, generators etc. In AC power network installations with frequency converters operating down to 5 Hz, the SIM-Q LF is the right choice. The main indicator is the instrument. Besides the instrument the SIM-Q is equipped with 3 LED indicators, 1 green and 2 red LEDs. Only the green indicator marked SUPERVISION is lit when the unit is connected to auxiliary supply and no insulation error is detected. The 2 red LED indicators marked +FAULT and -FAULT are illuminated, if an insulation error below the setpoint is detected. If a DC voltage occurs on the system together with an insulation error, the +FAULT or the -FAULT LED is illuminated, indicating the polarity of the DC voltage. This function will indicate the reason for the insulation error. The range from the lowest permissible insulation resistance to zero is marked with red. a standard 1000...0 kΩ scale with a standard red section from 11 to 0 kΩ. Also, a standard 10...0 MΩ scale with a standard red section from 0.44 to 0 MΩ. Bornika is the exclusive agent of DEIF company in the fields of consultation, sales and distribution of power industry products including Selectable Insulation Monitor.

Specifications
    • Operative voltage
    • Auxiliary voltage: Select between: 24V DC ±25% <4 W or 100, 110, 127V AC or 220, 230, 240V AC or 400, 450, 480V AC ±20% 40...70 Hz, <4 VA

    • Relay Output
    • By means of a built-in switch located under the rear cover the relay can be configured to either: NE : Recommended for alarm purposes. In case of an auxiliary supply drop-out the contact is immediately activated. It is recommended to supply the SIM-Q from a separate source, if this type is used. ND: Recommended for control purposes. Also recommended if the auxiliary supply for the SIM-Q is taken from the same power system under supervision.
