AWG UL rated stranded copper wire for connection to the meter. Differential elements 87B and 87C have values close to zero, but the A element has a value of 73 volts, indicating incorrect CT polarity, ratio, or wiring. and CT MAX - is the ideal solution when the safety level of the installation needs to be maximised. 10 for meter pole specifications. I then went outside and discovered the bypass around the meter. This paper dwells on the electronic meter (i. Wright-Hennepin's service manuals and wiring diagrams are useful tools when working on projects involving our electric products and meters. Watch a video to learn more about DENT power meters and loggers. terminals, their location and the internal meter wiring • In CT and VT connections, polarity must be observed for metering to be correct • CT's must be shorted when not in use; VT's should not be shorted • Meter multipliers are critical in transformer rated applications. The following versions of the meter are available: CoP5, Code of Practice 5 compliant, as well as CoP 2 and CoP 3. Premier 300 is and has enhanced event detection facilities and supports interoperable DLMS communications protocol. VISIONTEK 37CM Three Phase Electronic Energy Meter is a CT operated trivector meter designed to meetthe energy metering requirements of high power consumers. Compare Models. They are primarily used by medium consumers. Single Phase, 6 terminal meter socket prewired to a 6 pole test switch, (2) 200:5, Bar-type Current Transformers (CT’s) with a rating factor (RF) of 3. The meters can be connected in three-phase four- or three-wire networks, as well as in a single-phase two-wire network. 25 ohms < 0. All 32 failure modes of a meter circuit can be checked with the push of one button. differential protection). Step 9 Tong test the secondary CT wiring to confirm the CTs have been shorted and no current is present. See what patients have to say about Dr. This paper dwells on the electronic meter (i. The agency conducting the inspection generally is responsible for granting wiring permits.
