4.1.3 SAFETY FEATURES
(a). When the grid fails, it leads to “Islanding” of the local grid and the load from the main grid. As a safety measure, the PCU shall be disconnected immediately and power not exported to the grid i.e., protection against Islanding shall be provided. (b). The PCU shall have unique features like sleep mode, standby mode, invoke mode and export mode so that any disturbances on the grid such as overload short-circuit, over-voltage etc., disables the firing circuit of the PCU and causes it to quietly withdraw from the grid. 4.1.4 PROTECTION FEATURES
Over-voltage/surge protection shall be provided by using surge protection devices (SPDs) at the input and output of the inverter. The make of the SPDs shall be Phoenix/Obo Bettermann/equivalent. Vendor shall furnish the details of cooling mechanism provided for PCU for the heat extraction that is generated during the operation temperature rise details with in the cabinet when the PCU is operating at 80% of full load shall be mentioned in the offer at an ambient of 50°C.
4.1.5 Instruments for Meteorological Measurements:
Vendor shall provide following measuring instruments with all necessary software and hardware required to make it compatible with Data logger.Conditioned signal output for following sensors shall be provided for using them in Datalogger. Clamps and cable for installation of following sensors are part of supply.
Vendor shall provide Instrument manual in hard and soft form.
(a). Module Temperature sensor:
