Apex 100
Apex 100 is a long-range high-end precision meter, specifically designed for precise measurement at generation plants, transmission substations and bulk power transfer points. Multiple communications options make it fully compatible with existing substation systems, while providing future-proof capability and optimised engineering. Apex 100 supports widely accepted Modbus and ICS DLMS open data exchange protocols for ease of reading and integration with other systems.
Application
On-line monitoring of energy exchange at various interface points
Full four-quadrant import/export metering with active, reactive and apparent measurement, together with multiple communications channels makes it easy to integrate with e-Watch ss ABT and other monitoring systems.
Metering for availability-based tariffs (ABT) and open-access systems
Supports ABT tariffs and parameters required for measurement at grid interface points.
Key Feature
- Wide measuring current range (1-10 amp)
- Class 0.2S accuracy for active and reactive measurement
- Intuitive graphical display of electrical parameters and data
- Dynamic error compensation support for external CT/VT
- Simultaneous Modbus and DLMS communications over Ethernet port
- Multiple communications provision for local, remote and networking, e.g. optical, RS-232, RS-485, Ethernet and USB
- Standard industrial rack mounting

“APCPDCL has a road map to achieve a smart grid in the near future. That needs smart meters with communications channels, and input and output options. This makes the new Apex 100 meters suitable for APCPDCL, and does away with the need to reinvest in new metering when the smart grid is in place.”

“With the high range of secondary currents of 1A and 10A availability in the meter, we can use the same meter for 1A secondary current applications and also for 5A secondary current applications. With this facility in the meter we can limit the stock, as it is useful for 1A as well as 5A secondary currents.”
