Features:
The digital power meter GOBLIN PLUS is a micro-controller-based unit which not only measures a host of electrical parameters to display them on a 480 x 272 (RGB) smart TFT display (Touch), but also acts as a comprehensive load managing device due to its four numbers of output relay contacts. These outputs are individually field programmable for both the parameter on which to generate alarm as well as the values on which to activate alarm and deactivate it. In addition to this flexibility in terms of load management, the meter also has RS485 port. RS485 supports MODBUS RTU protocol for connections to EMS/SCADA.
The meter has four LEDs in the front, two to calibrate energies, one to indicate the status of RS485 communication and one to indicate DG Status.
GOBLIN PLUS is a versatile meter, with all the features needed to implement a robust electrical load management system. It can be configured to suit most control and communication needs.
Installation & Connection:
The CT Primary and Secondary, PT Ratio and installation types are site selectable, thus making it possible to use the meter in all types of installations like 3P4W, 3P3W and 1p2W.
Comprehensive Measurement:
In addition to basic metering of the previous models, GOBLIN PLUS adds support measurement of three energies for EB & DG, demands, logging of minimum-maximum values, all three types of power factors like True, Displacement and Distortion, Phase angle measurement, unbalance percentage and measured neutral current.
Power Quality Analysis as per IEC 610004-4-30 & IEC 61557-12:
For Power Quality Analysis - GOBLIN PLUS measures individual harmonics for all voltage and current waveforms, both even and odd, up to the 30th order, with THD as per IEC 61557-12. It also records in its non-volatile memory with date and time stamp, 180 Interruption events and 180 SAG/SWELL events, as per IEC 61000-4-30 standard.
Relay Output Options:
GOBLIN PLUS has four output relays, which can be used to manage loads. All relays are programmable for alarm parameter, value on which to close and open with the product’s ability to measure demand accurately, this can be used as an excellent Maximum Demand Controller.
Communication:
RS485 - The GOBLIN PLUS supports an isolated RS485 port for connection to EMS/SCADA application. RS485 communication status is indicated by RX/TX LED on the front of the unit.
USB Port - The GOBLIN PLUS can download the logged data directly into a USB Pen-Drive or through a cable to a utility software on a laptop.
Other Features:
480 x 272 (RGB) smart colour TFT display (Touch) makes it possible to display Harmonic data in histogram form and waveform of all voltages and currents, in addition to providing an intuitive and easy-to-operate GUI.
